Here’s a fast, informative look at parallel twin screw and barrel sets for extrusion lines. In this video, we demonstrate how nitriding and chrome plating deliver HV950–1100 hardness, show the twin-screw geometry and cooling options, and explain how the 0–600 rpm speed range affects mixing and wear. You’ll see real use insights on installation, maintenance, and performance so you can evaluate fit for your B2B extrusion process.
