Conical and cylindrical double-screw extruders

Extruders with counter-rotating conical screws, designed primarily for processing PVC in dry powder form (dry blend). Extruders equipped with a plasticizing system with precise thermostats, a raw material dispenser, and an extruded material degassing system.

Cylindrical extruders are made with concurrent and counter-rotating screws. They are designed for extrusion of granulates and regranulates, profiles, and pipes, as well as for extrusion of gas-foamed plastics.
