Editor?s note: The author, Donald E. De Laney, a consultant in polymer process rheology, worked with GE for 17 years and has worked with Dynisco over the past eight years. The plastics compounding and ...

This laboratory introduces students to the plastics manufacturing processes of twin screw extrusion, film extrusion, tube extrusion, and injection molding process monitoring. Experiments are designed ...

One of my first lessons in processor rankings was the formula for estimating extrusion sales based on material pricing and capacity. But commodity-based thinking no longer rules the day. Recent annual ...

With its diverse portfolio of polymer testing and sensing equipment, Dynisco is bringing rheology to the masses. Rheology is the investigation of the ­flow and deformation behavior of materials when ...

There are essentially three widely used technologies for manufacturing plastic products: Injection molding, extrusion, and blow molding. Injection molding is the most commonly used process for the ...
