Design of Highly Streamlined Extruder Screw to Minimize Formation of Gels and Black Specks
Speakers: Chris Rauwendaal | Rauwendaal Extrusion Engineering Inc.
Co-Author: Ned Uzelac | Performance Feed Screw Inc.

Defects such as gels and black specks are common challenges in sheet and film extrusion. The problem is more pronounced in film extrusion because small defects are highly visible in thin film. This presentation will describe the development of a highly streamlined extruder screw for single screw extruders and explain the principles behind it. This screw is called the Zero-Gels screw. A patent application for the Zero-Gels screw is pending. Detailed results of testing the Zero-Gels screw in blown film extrusion will be presented. Also, results of 3D CFD simulations of the Zero-Gels screw will be presented and compared to actual extrusion test results.

Machine Direction Orientation of Polymeric Films
Speakers: Steve Post | Windmoeller & Hoelscher
The orientation of polymeric films dates back to the 1930s when German scientist I.G. Farben oriented polystyrene film to make a stable, low-loss dielectric capacitor film. Subsequent decades saw developments in oriented polyamide fibers for stockings and parachutes during WWII. In the 1950s it was found that machine-
direction oriented films could be used for heat shrinkable sleeves. The big breakout for oriented polymers came in 1955 when E.I. Dupont commercialized their Mylar or biaxially oriented PET film. Ten years later, Showa Polymers in Japan introduced the first biaxially oriented polypropylene. Mono-oriented films were still used, but more for niche applications. Their big breakthrough came in the early twenty teens when the flexible packaging market began to look for BOPET replacements to make recyclable laminates or so-called mono-material packages. Since that time, more than two hundred MDOs have been installed globally. The presentation focuses on the physics behind the orientation of polymers, machinery design for different materials and how to optimize properties and control the process. Data is presented showing improvements to physical properties as well as the gaps that remain for creating a pure mono-material package.

Optimization of Sheet and Film Dies Using Flow Simulation Software
Speakers: Mahesh Gupta | Plastics Flow LLC
Designing dies for sheet and film extrusion presents the primary challenge of achieving a uniform velocity distribution at the die exit, which is crucial for minimizing thickness variation in the extruded product. For multilayer coextruded sheets and films, there is an additional challenge of maintaining a consistent layer thickness
across the extruded polymer. In sheet and cast film extrusion, a flat die with a coat-hanger-shaped manifold is commonly employed. The manifold ensures uniform velocity at the exit by effectively distributing the polymer across the die. Blown films, on the other hand, are extruded using a spiral mandrel annular die. The spiral groove in the mandrel overlaps multiple melt streams, eliminating weld lines and promoting circumferential flow uniformity. Flow simulation software, capable of accurately predicting velocity, pressure, temperature distributions, and layer structures in extruded sheets and films, serves as a powerful tool for designers of both coat-hanger and spiral mandrel dies. Unlike profile extrusion dies, which are highly customized, the geometries of coat-hanger and spiral-mandrel dies are well-established in the literature and can be easily parameterized using 3D CAD software like SolidWorks or Autodesk Inventor. As a result, die optimization software, which can automatically determine optimal values of the geometric parameters, can significantly accelerate die development for sheet and film extrusion. This presentation will discuss key design parameters for coat-hanger manifold and spiral mandrel dies. The polyXtrue software is utilized to accurately predict the velocity, pressure, temperature, and layer structure in the dies. Furthermore, die geometries for both coat-hanger manifold sheet dies and spiral mandrel blown film dies are optimized using the optiXtrue software. Results from these flow simulations and die optimizations will be presented and analyzed

The Molecular Homogenizer: Deterministic Elongational Mixing in a Single-Screw Metering Section
Speakers: Keith Luker | Randcastle Extrusion Systems
Deterministic elongational flow has evaded conventional single-screw extruder designs, which are dominated by shear-controlled transport and compression-driven mechanisms. This paper describes a single-screw metering architecture that produces primarily elongational deformation through
geometry rather than compression. The architecture employs three channels (C1, C2, C3) and two shear anchors (SA1, SA2) that supply and remove material in a controlled manner. The resulting flow is deterministic, primarily elongational, and overall trilongational, combining axial and rotational components. When multiple metering elements are used in sequence, recombination and reorientation between elements introduce multiplicity, enabling cumulative elongational deformation. The flow architecture, mechanisms, and appropriate applications for this type of mixing are described. With this elongational architecture, the single screw advances from high pressure pump to a high pressure compounder.

Troubleshooting Gels in Single Screw Extrusion and Film processes
Speakers: James Odom | Graham Engineering Company
An all too common issue that extrusion and film manufacturing face at some time period is issues with “gel” defects. These can be described as any small defect that distorts a film product visually and affects the performance and runnability of a
process. Eliminating these defects can be challenging, expensive and time consuming since significant scrap can be produced in a short period of time. Sources vary and include, but are not limited to contaminants, carbon, unmelted resin, high molecular weight material that isn’t crosslinked, and highly oxidized materials. Sources for these defects can originate from the resin manufacturer and from the process. Normally a system set up proper filtration produces a very clean product that can be maintained with proper maintenance. The focus of this presentation will cover first level countermeasures for this problem and more extensive solutions.

AI Automation for Short Run Color Sheet Extrusion Processing
Speakers: Douglas Brownfield | Ampacet Corporation
Sheet extrusion manufacturers are facing the challenges of JIT orders which require shorter runs. Producing quality color runs, economically, with minimal downtime is difficult to achieve. Stocking hundreds of custom colors to meet customer demands is expensive, causes raw material waste and takes up considerable valuable warehouse space. Using powder pigments to formulate colors is labor intensive and causes inconsistencies in color due to improper manual weighing. Making
adjustments during production using powder pigment batches causes downtime and lost production. Using pelletized mono pigments vs. powder pigments can offer lower manufacturing cost while enhancing quality due to greater uptime. AI equipment automation now exists that allows automated, accurate color weighing & blending without labor using a small palette of pelletized mono pigments or single pigment dispersions. Make color adjustments and corrections in-line and in real-time.
Takeaways:
1. Discuss the challenges of maintaining a profitable sheet extrusion manufacturing operation with customers growing demands of smaller lots.
2. New AI manufacturing technologies that eliminate labor and lowers production cost associated with running small lot color sheet runs.

Application of Automation Practices in Film Extrusion
Speakers: Kelly Chalmers | Applied Manufacturing
Traditional automation practices are rooted in rule-based systems, predefined instructions, and deeply embedded, rigid programming designed for high-volume, repetitive tasks. These practices focus on consistency and speed, often integrating directly into backend systems rather than mimicking user interfaces. Conventional automation integration can bring many valuable aspects to plastics manufacturing environments. But there are other times
when challenges specific to this industry require different strategies in how and when automation is best applied to manufacturing processes. This session will cover key considerations in plastics automation, including product variability, system flexibility, and the need to maintain safe and effective manual interaction.
