Machine Components

Die Head

Variable frequency controlled with adjustable rotation speed. Speed can be adjusted according to actual production requirements and raw material properties.

Screw

30:1 / 32:1 bimetallic screw options. Longer L/D ratio provides stronger plasticizing capacity. Bimetallic material features low thermal expansion coefficient and excellent wear resistance for stable production.

Gravimetric Doser

Standardly equipped with DEFINITI gravimetric doser for higher metering accuracy and longer service life.

Material Loader

Standard patented dual air outlet air ring with specially independent nozzle design. Stable and large air volume improves film cooling performance and effectively raises output capacity.

Air Ring

Solid state relays, PLC, enlarged display screen and switches are all internationally renowned brands, supporting continuous non stop operation.

Automatic Winder

Equipped with Chaoxin patented five roll traction system, consisting of traction roll, embossing roll, rubber roll, cooling water roll and polyurethane roll. Compared with competitors, two extra rolls are included. Curved roll and cooling water roll come as standard, delivering flatter film quality.
