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 ...

Determining the service or useful life of screw actuators – lead (acme), ball, and roller screws is a fundamental problem that faces many motion-system designers. In a broad sense, a screw’s service ...

Ball screws and roller screws are widely used for high-force linear motion and are replacing fluid power devices. In general, these screw mechanisms generate linear motion by rotating either the screw ...

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 ...
