Recycling Gold Rush – How to use your “picks and shovels”, Paul Martin, Krauss Maffei

In the context of the polymer recycling industry, the term "picks and shovels" refers to the foundational tools, technologies, or services that support the industry's operations rather than the end products or direct recycling processes. This approach is inspired by the Gold Rush analogy, where those selling the tools often profited more consistently than the miners themselves

Controlled Viscosity Molding, Rick Fitzpatrick, X2F

Most polymer and process engineers view plastics through the lens of conventional extrusion and injection molding. This perspective limits their understanding of polymer behavior, as traditional injection molding relies on high pressure and velocity to shear polymers, reducing viscosity for mold filling. This fixed-input approach overlooks the non-Newtonian nature of polymer melts, where pressure increases viscosity, necessitating large machines and molds and restricting the range of processable thermoplastics.

Controlled Viscosity Molding (CVM) disrupts this paradigm by leveraging the non-Newtonian properties of polymer melts to achieve flow and mold filling through extrusion, using far less pressure and offering superior precision. This counterintuitive, low-velocity method redefines product design, material options, and processing capabilities. By integrating data and algorithms conventional molding processes cannot, CVM delivers a fixed-output process adaptable to any thermoplastic, challenging conventional assumptions and unlocking new potential.

Pack Pressure’s Influence on Gate Freeze Time, Zach Morton, American Injection Molding Institute

An important step in developing a consistent injection molding process is determining the time required for a cavity’s gate to fully solidify. Gate solidification marks the instant at which plastic flow into or out of the mold’s cavities is no longer possible. This moment is commonly referred to as gate seal or gate freeze time. Research will be presented to show the relationship between pack pressure and gate freeze time using the AIM Institute’s process development methodology on a variety of processes, including three materials and four different molds. The investigation will include a brief review of each material’s compressibility and pvT profile. Finally, this presentation will explore how these findings may warrant changes to standard process development methodology.

Pressure Drop Studies…Are Air Shot Pressures Accurate?, David Hoffman, American Injection Molding Institute

Most processors these days are taught to do a Pressure Loss Study as part of their Scientific Molding practices. The main purposes for the study include: 1. determine which sections of the material flow path are consuming the greatest amount of pressure, 2. determine how much pressure is required to fill the mold by subtracting the air shot pressure from the machine’s pressure at transfer, and 3. determine the accuracy of mold filling simulation pressure predictions. Previous research will be summarized that shows errors with the practice of doing pressure loss studies at various steps through the mold. This will build into recent research that now questions the accuracy of the air shot pressure, in particular for materials whose viscosity is pressure sensitive. Studies will be shown that compare the pressure loss both during an air shot and during the molding cycle by incorporating a pressure sensor in the machine nozzle tip. The results will also be compared to Autodesk Moldflow simulation predictions, and how differences in the pressures could be misinterpreted. The research could ultimately call into question the entire practice of performing Pressure Loss Studies for some materials.

Lightweighting of Plastic Injection Mold Inserts, Scott Kraemer, Xact Metal

For too long, we have tried to adopt 3d metal printing into mold making. However, it has not been thought through. It has been a combination of old-world brick making and then adding conformal cooling and calling it additive. While that is true, it is not taking full advantage of what the technology can offer. In some cases, the adoption of just adding conformal cooling is the best option. But to truly think differently, you need to rethink how you “could” do it. Why not infill with lattice structure? Or why not make them hollow? You could still add conformal cooling or just flood the lattice work with water. Why not learn what we can and take this technology to the next level? Listen as we explore the world of lightweighting mold inserts and experience what the future of mold making can be.

Innovative Hybrid Molding Concepts for Cost-efficient Manufacturing of Multi-Material/Functional Components, Saeed Farahani, Clemson University

Advanced multi-material structures are known for their superior characteristics due to the synergy of different materials. However, the multi-stage and high cost of their manufacturing processes are the main drawbacks in expanding their application in cost-effective industries such as automotive. To counter these challenges, hybrid manufacturing approaches can be utilized to overcome limitations associated with earlier technologies, while adapting themselves to incorporate new materials and unique features. Moreover, hybrid manufacturing increases the complexity and technical requirements of the system, thereby making product imitation difficult. Motivated by the aforementioned aspects, several innovative hybrid molding concepts have recently been developed by our research group on the intersection of plastic injection molding process with forming, foaming, and additive manufacturing processes, which will be introduced in this presentation. While these concepts were initially proposed to overcome the manufacturing difficulties of multi-material components, the unique design flexibility provided by these integrations hypothesizes such hybrid technologies as a promising pathway towards cost-efficiently manufacturing of composites and multi-material parts while increasing their performance and functionality.
