In the plastics industry, twin screws are at the very heart of the extrusion process that transforms raw materials into rigid PVC pipe or profile. These highly engineered components are integral to ...

I teach a one-day Intro to Extrusion seminar, and many of my participants are new to extrusion. Therefore, I explain the basic principles of screws for thermoplastics. That’s good for the newbies, but ...

The extrusion division of the Society of Plastics Engineers and the chapter representing the Eastern New England section are offering a new screw design conference called Topcon. The two-day gathering ...

Extrusion is a process used for creating a product (an extrudate) by forcing a material through a die or an orifice to form a shape, or alternatively an extruder is used to produce semi-finished or ...

As new analytical technologies advance, insight into the twin-screw granulation process is growing. The range of applications for twin-screw extruders as pharmaceutical manufacturing equipment—either ...

Atlanta — The plastics materials sector is responding to today's stronger-than-ever "green" momentum by developing bioplastics and beefing up recycled content, both mechanical and chemical. And ...
