The twin screw extruder barrels are segmented into sections. The standard material is nitrided steel, but a wide variety of other materials are available such as bimetallic liners for highly corrosive and highly abrasive materials. Segmented barrels available are designed for conveying/mixing (no holes), top feed, glass fiber feed, side feed, liquid/gas injection, pressure monitoring, venting, or other custom ports. Each barrel segment is standard with cast aluminum or bronze heaters with air or liquid cooling.
Barrel length and mounting position can be configured in various ways, due to its modular barrel design. Feed barrel, closed barrel, vent barrel, open barrel, combi barrel, extended degassing vent barrel, barrel with drillings for measuring/injection, combi barrel with backward venting and adapter plate can be changed according to the raw material and/or functionality requirements.
