Designed for extrusion of PVC pipes, C-profiles (doors & windows), wood-plastic composites, foaming, and pelletizing.

The screw is made of high-quality alloy steel, precisely machined, quenched, and nitrided to achieve optimal hardness and corrosion resistance. Specially designed screws are equipped with forced-feed bushings, featuring a well-engineered structure, stable performance, excellent plasticizing, high...

Equipped with specialized screws, suitable for PVC, PE, PBT, PA6, low-smoke halogen-free (LSZH), fluoroplastics, XLPE cross-linked production lines, and coaxial physical foaming insulation.

Specifications: Φ150 – Φ250 mm
Designed to filter impurities from natural rubber, butyl rubber (IIR), EPDM, silicone rubber (SIR), and recycled rubber.
Equipped with a twin-feed system, allowing pelletized or chunked rubber to be fed smoothly, without the need for pre-extruded rubber strips.
