Tuesday General Sessions

8:00am-8:30am Data Collection and Analysis in Extrusion

Presented By: Chris Rauwendaal, Rauwendaal Extrusion Engineering Current data acquisition systems tend to be expensive, difficult to use, and often present the user with an overwhelming amount of data. If a DAS is not user friendly it will not be fully utilized or not used at all. In this paper, we present a new data collection & analysis (DCA) system that is not only user-friendly but also provides the user with an analysis and interpretation of the data. This DCA system focuses on the vital signs of the extrusion process rather than all process variables. The vital signs are melt pressure, melt temperature, and motor load. In addition, the system will monitor screw speed and line speed. The customer will be able to see trend plots of the vital signs on their extrusion line and elsewhere using internet connected devices. The system will be cloud-based. The unique part of the system is that it performs in-depth analysis of the data and provides the results on this analysis to the customer. This will allow determination of the level and nature of the process variation. The DCA system can detect problems and determine when maintenance is required for certain parts of the extruder. The system will also be able to provide remote troubleshooting using the process information we collect. The system provides status reports to the customer on a regular basis. The DCA system will measure and collect data 100 times per second. At this data collection rate short-term variation can be accurately assessed. Systems that collect data once per second or slower cannot accurately determine short-term process variation over a time period less than one second. This is problematic in extrusion because every extrusion process is subject to short-term variation. Add to MyShow Planner

10:30am-11:00am One-Step Size Reduction: The Latest Developments in Shredding

Presented By: Dana Darley, Vecoplan LLA A review of the latest vertical and horizontal shredding systems for processing all types and shapes of extruded scrap down to usable particle size. Traditionally, shredders have been limited to particle sizes of 1" to 1-1/2”, requiring further size reduction through a granulator to reach the required 3/8" or smaller particle size for re-processing. The challenge has been to move cutting technology from a pierce and tear approach to more of a cutting action, simulating the cutting action of granulator blades. The second challenge is cutting power and capacity…shredders are typically setup for high cutting power, with limited cutting capacity. One-step size reduction requires both high power and high cutting capacity, all while managing processing temperatures. Higher rotor speeds, cutting torque and number of cutting tools, also puts increased demands on the shredder design, which must be much more robust. The Vecoplan VIZ vertical and VKH horizontal represent the latest in size reduction technology, making one-step size reduction for a growing number of applications a reality. Add to MyShow Planner

11:00am-11:30am Blending and Control Options for The Extrusion Processor

11:30am-12:00pm Where to Remove Fines and Streamers

Presented By: Joe Lutz, Pelletron In today’s market place, clean resin without streamers and with a remaining dust content below 50 parts per million (ppm) is the requirement. Many resin producers find it difficult to meet this standard with their existing pneumatic conveying and dust removal systems. Therefore, these contaminants need to be removed before your extrusion process so that the material that you melt is free of streamers and dust. Melting clean material yields better quality end products and less maintenance headaches. Fortunately, there are various established methods for minimizing the generation of dust and streamers and efficiently removing these contaminants. Unfortunately, there is no “one size fits all” solution. One simple approach is to modify an existing high-speed dilute phase pneumatic transfer system into a custom designed Strandphase® transfer system that uses lower velocity conveying gas. Along with replacing standard pipe bends with special elbows like the Pellbow, you can drastically reduce attrition created by conveying your material. Test results show the convey gas velocity and the type of elbow used is directly proportional to dust and streamer generation. A video demonstrates how the proprietary Pellbow works. Even the most efficient conveying system will still create some dust and maybe even some streamers. The best way to remove dust and streamers is using a dedusting system designed specifically for granular plastic products. The Pelletron DeDuster is designed to remove even electrostatically charged dust and very long streamers in one system. Every application is different but it is recommended that a DeDuster® be mounted directly to the inlet of an extruder, injection molding machine or packaging silo outlet to ensure the best quality material is being used downstream. A video demonstrates the working principle of the DeDuster. Add to MyShow Planner

12:00pm-1:00pm Lunch Presentation: Is Old Technology Thwarting Your Ability to Attract Employees

Presented By: Dustin Barlow, Integrated Control Technologies Imagine that a Millennial took a job at a call center and all they had to work with were rotory phones. Although the company had good benefits and there was a history of life-long employees, the new employee became quickly frustrated and resigned. It might be the conclusion of the management that the next generation was not as loyal or had the level of commitment of previous generations. Although there may be some truth to that statement, it has nothing to do with their resignation. Therefore, it is possible that machinery utilizing obsolete technology for control can result in poor employee retention as well as keeping the best and the brightest employees away. This presentation discusses this and how making the proper investments in your machinery today will help guarantee a more profitable future and attract better employees. Add to MyShow Planner

Tuesday Film & Sheet

1:00pm-1:30pm Trends in Melt Filtration for Sheet

Presented By: Monika Gneuss, Gneuss Inc. Screen changers or other melt filtration devices play a key role in extrusion applications in removing contamination, such as paper, wood, aluminum foil, rubber, gels or other unwanted plastics. Filtration is a requirement for most extrusion lines today and can have a significant impact on the production line efficiency and end product quality. At the same time, melt streams are becoming more and more contaminated, as processors are using more reclaimed materials. Reclaim source, whether industrial or post consumer, and desired filtration fineness play an important role when choosing the right filtration technology. Rotary Melt Filtration systems can offer solutions for challenging applications. Several case studies will be presented. Add to MyShow Planner

1:30pm-2:00pm Screw Design Differences Between Smooth Bore Designs, and Grooved Feed Extrusion Applications

Presented By: Walter Smith, Xaloy Extrusion screw designs are designed differently, depending; if the machine is a smooth bore machine, or a grooved feed machine. The screw designer also, must take into account the machine configuration, whether the machine is a (2) piece configuration, or a one-piece; thru barrel configuration. The (2) piece configuration is a seperate feed section, bolted upstream of the extrusion barrel, with an air gap between the two peices, thermally isolating the barrel, from the feedblock. The one-piece configuration, is a one piece, thru barrel, with the feed port machine into the barrel itself, which is not theramally isolated. Add to MyShow Planner

4:30pm-5:00pm Non-Nuclear Online Sensors for the Direct Thickness Measurement of Polymer Film and Sheet

Presented By: Eric Reber, Mahlo The extrusion industry has lived with the use of nuclear gauges (Beta, Gamma) for the online measurement of film and sheet "thickness", even though these types of gauges really measure basis weight from which thickness must be inferred. If there are density changes in the extrudate caused by the addition of colorants, opacifiers, or any other chemical additives, then the thickness calibration of the basis weight gauge will shift which can result in significant errors. Advances in UV, visible and infrared optical interferometry have resulted in a family of online direct caliper sensors for the measurement of films down to sub-micron thicknesses. Also, Improvements in high resolution optical distance sensors are now replacing nuclear basis weight gauges for the direct thickness of extruded sheet. The physical principles of these sensors are presented along with their real-world performance in industrial manufacturing environments. Add to MyShow Planner

Presented By: John Perdikoulias, Compuplast A newly-developed simulation software is used to analyze the performance of closely intermeshing self-wiping corotating twin-screw extruders. This software implements simulations based on a macroscopic composite model for non-isothermal plasticating extrusion of polymeric materials enabling the computation of simulation results within a few seconds. It can be used for design and optimization purposes for conventional as well as reactive extrusion applications. Required inputs include screw and barrel configuration, material properties and processing conditions while outputs include axial profiles of key variables such as pressure, temperature, degree-of-fill, stress and deformation rate as well as overall residence time distribution and specific energy consumption. The functionality of this simulation software will be demonstrated through numerical simulations in selected polymer compounding and pharmaceutical applications. The software is developed using a server-client model, so that the client component of the software requires minimal resources. The client graphical user interface (GUI) has been developed as a web application for cross-platform compatibility and may be used on any computer or mobile portable device with an HTML5 compliant web browser.

Tuesday PPT

1:00pm-1:30pm Rubber and Silicone Extrusion Basics

Presented By: Bill Kramer, US Extruders Processors wanting to expand into rubber or silicone extrusion need be aware of the basic differences as compared to plastic extrusion. Silicone typically needs to be mixed on a mill prior to extrusion, and both types of elastomers are normally fed in strip form to the extruder via a roller feeder. Extruders designed for elastomers are shorter than plastic machines and operate much cooler. The extrudate is heated for vulcanization after the die exit instead of cooled as in plastics. Extruder design requirements for rubber and silicone are discussed as well as processing basics. Add to MyShow Planner

2:00pm-2:30pm Progress in Inline Pipe Measurements: Radar Technology Comes to Extrusion

Presented By: Jan Petermann, Inoex For several decades now plastic pipes have been measured inline. However, currently used technologies also challenge the user in many ways, either by elaborate conversion work on the system for dimensional changes or by frequent calibration procedures or in some cases the use of water as coupling medium.

4:00pm-4:30pm How Inline Grinding Can Help Support Extrusion Workflow

Presented By: Andre Adams, ACS & Max Cummings, Teel Plastics No matter what type of process is the mainstay of your plastics manufacturing operation – injection molding, thermoforming, extrusion – every floor manager knows that the waste materials generated can be significant. Ideally, those materials are reclaimed back into the process. By grinding the plastic materials down to a size that’s similar to the virgin material, you drastically decrease waste and mitigate the amount of virgin material in the process.
Regardless of the size of your operation or type of manufacturing process, regrinding of plastic components has the potential to create substantial savings. There are multiple types of size reduction equipment including shredders and granulators that can be used to transform the material into a more useable state. The type of machines utilized in a process depend on the material characteristics, size and density. Considering the annual savings over many manufacturing cycles, it’s vital that the right type of granulator is chosen based on your unique plastic processing operation, type of materials, labor, floor and storage space, and many other factors.
To help get the most from regrinding, plastics manufacturers typically use one of two types of manufacturing floor configurations and the equipment designed for that workflow – a central granulator or a beside-the-press/extruder (inline) granulator. (It should be noted that Under-the-Press (UTP) granulators are sometimes categorized with inline granulators, although they are generally located beneath a plastics thermoforming line) Each approach to regrinding has pros and cons that are unique to each operation, so the onus is on floor managers and manufacturing engineers – with the help of a knowledgeable equipment partner – to determine what works best to meet the company’s unique needs, limitations, and goals.
Although a central granulator configuration offers many benefits for those operations that are well-suited for that equipment, this white paper will focus on inline granulators. We’ll explore the top reasons you might want to choose this type of granulator equipment for your plastics extrusion process, as well as other considerations. Add to MyShow Planner

Wednesday General Sessions

7:30am-8:00am Investing in Aging Equipment

Presented By: Dan Barlow, Integrated Control Technologies Investment is the act of putting money or effort into something to make a profit or achieve a result for a future benefit. There is a big difference between money spent on repairing a machine to get a line running as opposed to upgrading the machine in such a way that it not only solves the problem today but also addresses the challenges of tomorrow. Repair of a machine requires little planning and it usually does not solve the problem, especially if it can happen again. In such cases, we are "kicking the can down the road" leaving the problem for someone else to solve. Investment requires planning and commitment and is pro-active as opposed to re-active in behavior. Proper risk assessment and planning are required when considering an upgrade. All upgrades should include five important factors to guarantee a future benefit. Add to MyShow Planner

8:00am-8:30am Removing the Myth Between Melting Point and Processing Temperature

Presented By: Braulio Polanco, Scientific Extrusion One of the biggest challenges for plastic processors is inconsistency in polymer quality. In some cases, the polymer lot to lot variation can be so significant that will require changes to the process. However, very few companies invest in equipment to test the polymer to understand its thermal characteristics and flow behavior. In many extrusion and molding operations, changing the process temperature is almost forbidden. This is in part due to the lack of information about polymers and how they behave. In this session, we will define melting point and scientifically show how processing temperature is derived. In addition, we will demonstrate relevant polymer testing data that will clear the misperception that melting point correlates to processing temperature. Add to MyShow Planner

Presented By: Alan Landers, Conair The IoT push in our industry over the past 5 years has driven rapid technology advancement that allows for smarter processing and smarter factories. The newest control systems not only govern machine operation, they also monitor and record a host of setpoint and actual process parameters that can be viewed on a dashboard that displays individual pieces of equipment, entire lines, entire plants, or entire companies. That data can usually be downloaded manually or automatically to various database systems and compiled into reports and analyses that can support process-optimization and productivity-enhancement programs. Powerful equipment monitoring and visualization functions, plus advanced cloud-based data storage and analytics that were barely a dream 5 years ago, are now available. By NPE2021, there will be even more developments. If you order a piece of equipment, or an entire processing line at NPE2021, the equipment you receive will be the most advanced ever produced in our industry. These newest developments will help molders not only collect and analyze information, but utilize it to achieve new levels of process, performance and quality optimization.

11:30am-12:00pm Understanding the Advantages of Using Pressure Control to Minimize the Effect of Process Variations

Presented By: Kevin Slusarz, US Extruders Pressure control is a process enhancement that allows for a control system to make changes to an extruder. Using the principal that a constant pressure drop through a fixed resistance is equivalent to a consistent mass flow rate. This control system will maintain a consistent output, minimizing or eliminating a product to exceed specifications. Based on this and using a PID control loop, small changes in screw speed are used to maintain a constant pressure. The data presented in this paper will be a series of case studies showing common process changes that can affect the output of an extruder and compare the reaction time of pressure control versus no control. The paper will compare pressure control to no control and then evaluate common variations seen in production such as temperature changes in the raw material and bulk density changes.

3:30pm-4:00pm Modern Extrusion Die Technology for Sheet Applications

Presented By: Sam Iuliano, Nordson Sheet extrusion die technology has undergone rapid development over the past decade. While features such as a basic chocker bar for distribution control, exchangeable lips, and standard external deckles are still being used today; newer and more efficient extrusion die features are a better fit for most processors. Now available is motorized variation of the die lip exit gap while simultaneously controlling a critical variable - the internal lip land length. New restrictor bar mechanisms now can tune the flow distribution from a single adjusting point, making control faster and more repeatable. The latest sheet width adjustment systems combine internal with external deckles to reduce the size of the edge beads - allowing for sheet thickness tolerances to be achieved with minimal operator intervention and reduced edge trim requirements.

1:30pm-2:00pm A Scale-up of Journey: Pharmaceutical Class Compounds Developed via Twin Screw Extrusion

Presented By: Brian Haight, Leistritz Extrusion Thermally sensitive active ingredients and water-soluble polymers are processed via twin screw extrusion to manufacture many of prescription drugs we ingest every day. In early stage development, very limited (and expensive) amounts of materials are available. Hence, atypical twin screw extruder geometries are used to process small batches of less than 50 gm to test the feasibility of a formulation. If deemed viable, scale-up to more conventional twin screw configurations is the next step. Studies were performed to optimize the processing a thermally labile drug with a water soluble, pharmaceutical grade polymer. Initial studies were performed on a nano-16 co-rotating twin screw extruder with 1.2 OD/ID ratio, then a ZSE-18 co-rotating twin screw extruder with 1.5 OD/ID ratio, and then a ZSE-27 counter-rotating twin screw extruder with 1.5 OD/ID ratio. Once the mixing mechanism and boundary conditions were understood, successful scale-up was the result. The lessons learned may be applied to any extrusion scale-up exercise. Add to MyShow Planner

2:30pm-3:00pm Oxo-Biodegradables and the Future Of Plastics

Presented By: Robert Dalleska, Color for Plastics Every week news outlets throughout this country report on some form of plastics waste issue. From Plastics news in June of 2019 there were 8 such articles. In Jan of 2020 there were nearly double at 15. Crain Communications believes so strongly in the effects sustainability and recycling will have on the plastics industry they rebranded the European version of Plastics News to be titled Sustainable Plastics. OXO-Biodegradables are another excellent opportunity for the plastics industry to get ahead of the public outcry to divest themselves from plastics completely. Aside from working toward sustainability we can take action immediately for single use and disposable plastic products in the form of OXO-Biodegradables. OXO Biodegradable additives enhance oxo-biodegradation of plastic products into more environmentally safe byproducts. They are engineered to promote oxidation, leading to the molecular breakdown of plastic. Microorganisms then complete the biodegradation process, metabolizing the remaining polymer structure as food, generating water, carbon dioxide and biomass (humus) as by-products. OXO-Biodegradables assist in shortening the lifecycle of polypropylene (PP) and polyethylene (PE) plastics products. Suitable applications include bag, film, garden, agricultural, food packaging and container/utensils, cap and closures, strapping, toothbrushes, golf tees – the list is long and growing. Our technical experts can assist you to determine the suitability of your specific product application for OBPA treatment. OXO-Biodegradables are cost-effective – they typically only add 1-4% to material costs depending on the product and lifecycle expectancy. These additives are handled just like color additives, requiring no special handling techniques or new equipment. OXO-Biodegradables are proven to be recyclable in both industrial and post-consumer recycling streams with no detrimetal effects on the resulting recyclable. They are shown to be non-toxic to sensitive plant, animal and aquatic life. Without the transition of plastic into digestible material, normal plastic products will persist in the environment without any need. Add to MyShow Planner

3:30pm-4:00pm Historical Perspective of the ZSK Twin Screw Extruder with a View to the Compounding Line of 2030

Presented By: Sabine Schoenfeld, Coperion Application requirements for polymers continue to push the performance envelope with respect to better qualities, improved characteristics and lower costs to name a few. For the manufacturer to meet these requirements and still make a profit, the compounding line needs to operate efficiently with maximal output, a high onstream factor and minimal off spec product. The co-rotating fully intermeshing twin-screw extruder continues to be the primary technology for compounding applications. The most significant reason is that is has not become a mature technology but has continued to evolve during the intervening years since it was commercialized in 1957. For example, in the past 20 years several significant developments have been introduced. These include a) the implementation of high torque (power) designs, b) the use of increased screw rpm in conjunction with high torque for improved operating flexibility and productivity, c) a breakthrough technology for feeding difficult to handle low bulk density materials and d) new geometry elements for improved melting and mixing. In addition to mechanical related advances, drive and control systems have also improved over the years. DC motors and drives have been replaced by more efficient AC systems. RPM and temperature controls have migrated from analog to digital. Hand written data sheets have been replaced by data acquisition systems capable of real time system performance analysis. Some offline QC, such as Melt Index, can be integrated into the compounding line. The above is a partial list of advancements in the 60 plus years since the twin-screw was introduced, but what about the future. What compounding technology advancements will occur over the next ten years? This presentation will bring up ideas about the design and capabilities of and around the compounding line in 2030. On the one hand, by selecting suitable calculation programs, it is possible to transfer a new process to production machines without long-term test series. We will present some examples of how finite element method simulations can be implemented in the design of a new line. On the other hand, the integration of Industry 4.0 certainly offers the possibility to run a more efficient production. Add to MyShow Planner

1:00pm-1:30pm Your Old Puller Could be Used as a Pitching Machine or a Boat Anchor, Not as Part of Your Extrusion Line

Presented By: David Czarnik, Conair Twenty years ago, extrusion pullers weren’t much different than the pitching machines available in the batting cages at your local high school baseball camp. Plug it in, set a speed, and start running. One pitch come at you at 54 mph, and the next one could be 63 mph. One hour your puller is running at 100 feet-per minute the next it’s at 111 feet-per minute. Close enough, right? That’s not the case today. Today’s pullers are extremely precise. This precision is necessary if your process counts on stability, consistency, and quality. Since pullers regulate extrusion speed, sizing, surface finish, wall thickness, cooling, and mechanical properties, the precision of the puller is of the utmost importance to your process. The most precise variable speed pullers of 10 years ago, were considered “perfect” at ±1 to 2%. Typical pullers today feature a choice of vector or servo drives. Both are considered brushless AC drives, and both deliver a far, far greater degree of speed regulation and precision than the drives of even a few years back. Today, speed regulation accuracy for brushless AC motor drives is 10 to 100 times better, ranging from ±0.1% for high-quality vector drives to ±0.01% for quality servo drives. This presentation will explain the differences between yesterday’s pullers, todays, and even tomorrows pullers. Increased precision, improved controls, improved programming, repeatable consistency, and a wide range of speeds with constant torque are advancements that affect the bottom line. Today’s precision pullers – there’s no reason not to take advantage of the return on investment. Add to MyShow Planner

1:30pm-2:00pm A New Software Tool for Efficient Profile Die Engineering and Optimization Using Both 2D and 3D FEM Flow Analysis

Presented By: John Perdikoulias, Compuplast A new simulation package has been developed that allows users to use both a 2D or fully 3D FEM flow analysis for Profile Die engineering and optimization. In addition to the traditional, 2D cross section analysis, the software can easily import a 3D FEM mesh and automatically, apply the required boundary conditions. After the 3D FEM simulation has completed, the user can easily post process the results, using “Path lines” or “Cuts”, for correct flow field characteristics and distribution. The software also incorporates the previously presented “Profile Digitizer” which allows users to easily and precisely quantify the extruded product shape for comparison with the simulation results, using their mobile phone camera. This information can then be applied towards “calibrating” the simulation for small errors in material properties and then making precise adjustments to the die geometry for improved flow distribution and final product shape. Using this methodology often reduces typical die development to 2 or 3 trials. Users that already have experience with a particular material can often use the software to achieve an acceptable product with the initial trial thereby saving considerable amount of material and time.

2:30pm-3:00pm A Unique Method of Curing Low Durometer Urethanes in an Inline Process

Presented By: Bob Bessemer, Novatec Extruding low durometer urethane medical tubing is a challenge for several reasons. The tubing is so tacky that if the tubes touch each other, they can't be separated when cutting; also, if the tube is flattened, it does not rebound. To overcome these challenges the tubes are typically cut to a longer length than required and manually hung on racks for 24 hours and allowed to dry, then they are cut-to-length manually, which requires high labor usage and costs. I will discuss a new low durometer tube processing method that can help to solve these challenges. I will show how to extrude, cool, cut, and cure extremely tacky urethane tubing in an inline process. This technology includes, a three-temperature zone multi-pass vacuum tank to enhance the surface characteristics of the urethane tube, minimize stretch and allow precision cutting to desired length in line. The cut tube will then be ejected to a perpendicular conveyor oven outfitted with a stepping system to enable the cut tubes to travel through a heated chamber (165-170° F) for approximately one hour with the tube exiting the oven in a cured state. We will discuss in detail, the effect of the tube traveling through the tank going from hot, to cold, to warm water zones, as well as why the tube is maintained in a water bath for longer than typical with the use of a three-pass tank with two servo-driven wheels. We will also discuss how the tubing can normalize in the process to minimize shrinkage. This solution represents a cost and time-saving solution to a problem medical tube processors have been working to overcome for years. Add to MyShow Planner

3:30pm-4:00pm Simulation of Extrudate Cooling, Shrinkage and Distortion in a Multi-calibrator Post-die System of a Complex Extrusion Die

Presented By: Mahesh Gupta, Plastics Flow During extrusion of complex profiles with multiple pockets, such as those used for manufacturing of PVC windows, some (or all) of the external walls of the extruded profile are in contact with the calibrator walls. Vacuum in the calibrators pulls these external walls to the calibrator surface. However, internal walls of the profile and the external walls which are not in contact with the calibrator surface, continue to distort as the extrudate goes through the calibrators in the post-die system. Post-die analysis of multi-pocketed extrudate profiles is particularly complex because thicknesses of external and internal walls are typically quite different. Furthermore, the cooling rate, shrinkage and distortion of external walls are also very different from those of the internal walls. The presentation will discuss the simulation results for flow in a complex bilayer coextrusion profile die combined with the analysis of extrudate cooling and distortion as it goes through multiple calibrators in the post-die system. Different cooling rates are enforced on the extrudate walls which are in contact with a calibrator, on external extrudate walls which are not in contact with a calibrator and on internal walls of the extrudate. The extrudate is analyzed as a fluid near the die exit and then analyzed as a solid by a thermo-mechanical analysis away from the exit. Effect of non-uniform velocity at the die exit as well as that of cooling shrinkage on extrudate distortion is included in the simulation. Add to MyShow Planner

9:30am-10:00am Rheology as Opposed to Melt Index as a QC Test

Presented By: Steve Post, Thermo Fisher The primary instrument used by the industry to qualify the rheological properties of a raw material is the melt index test. But melt index is really a crude test and does not define the rheological or physical properties – catalyst technology, long chain branching and molecular weight distribution have so much more impact on the behavior of the material in the process as well as the end physical properties. Rheometers are far from being new devices, but have always been too sensitive, expensive or labor intensive to be used in a normal QC environment. We will examine three different LLDs; all with the same melt index, but with different rheological curves. Add to MyShow Planner

Presented By: Azadeh Farahanchi, Dynisco The growing tendency towards productivity, efficiency, and sustainability among manufactures and recyclers in the plastics industry arises the necessity of timely control of the process and quality while eliminating the waste amount. Online rheometers have increasingly been used in variety of extrusion lines in order to have continuous data stream of rheological properties and real-time information on the process without any delay for the laboratory testing. A newly designed online rheometer has been developed to duplicate the test conditions of laboratory rheometers, continuously provide information on the melt flow rate (MFR), shear viscosity, intrinsic viscosity, and extensional viscosity of in-process extrudate materials. The present work aims to describe how this online rheometer has been designed on an extruder to constantly control the amount of volumetric flow rate and driving pressure while considering the effect of reservoir pressure, entrance pressure drop, and capillary diameter. As a result, this online system continually measures various rheological parameters which closely matches those from a melt indexer or a capillary rheometer. Moreover, through calculation of activation energy for a specific material and introducing a temperature correlation, it has been investigated how this online rheometer considers the temperature dependency of material`s rheological properties and accurately measures these parameters at various operating temperatures.
