Sort by Number - a project on plastics recycling

The laboratories of the Polymer Engineering Center have a wide range of polymer-processing machines, including an Arburg 55-ton co-injection molding machine with MuCell capability, a Welding Engineers counter-rotating twin screw extruder, a Brabender batch mixer, an Engel 55-ton tiebarless injection molding machine, a lab-scale 8-ton injection molding machine with a Liquid Silicone Rubber unit, blow molding and thermoforming equipment, a film blowing line and a Selective Laser Sintering Machine. Recently, faculty at PEC received a Major Research Instrumentation (MRI) grant from NSF to acquire a modular, instrumented single-screw extruder with sensors and a multi-function co-injection molding machine as experimental instruments for both research and education at the PEC. In addition, our center has a variety of measuring equipment such as a special patented Sliding-plate rheometer, an AR1000 R&D grade rheometer, a Dynamic Mechanical Analysis (DMA), and an on-loan Differential Scanning Calorimeter (DSC) for material characterization.

Computing Resources

The PEC computer laboratory is equipped with several workstations used for modeling and simulation. In-house research codes and many polymer-related commercial CAE software packages, including COMSOL, PAM-RTM, C-MOLD, CADMOULD, CADPRESS, and Moldflow, are available for educational and research purposes. The commercial compression molding software, CADPRESS, was originally developed at the center.


Printing prototypes in the Selective Laser Sintering machine is available for students and faculty at the University of Wisconsin-Madison. For more information, follow the link below.
