Description

Product Introduction

Casting stick

Driven by an independent motor, the rotation speed is adjustable, the surface of the roller is hard chrome plated, and the roller frame can be moved up and down by a lift.
Each roller features independent servo motor drive technology, enabling precise speed control and adjustable speed ratios between adjacent rollers for superior calendering accuracy.

Main motor

High-performance servo motor (1500r/min rated speed)

with a heavy-duty reduction box ensures reliable axial

thrust resistance for precision screw-driven extrusion.

Boost material plasticizing performance with an

optional screen changer or melt pump system

for enhanced extrusion efficiency and consistency.

Smart Operation

All parameter settings, system control, data recording, etc. are operated/displayed through the operation screen installed on the door panel.
Small size, small footprint, suitable for use in laboratories.

Winding components

The air shaft is driven by a torque motor with an adjustable

rotation speed. The air shaft can drive the paper roll to rewind.

Hard chrome-plated mirror roller with 304

stainless steel roller core, high surface finish and no rust.

Trimming and Rolling

The film is then passed through a sequence of cold, polishing, and nip rolls to help form the desired thickness. It is then trimmed and wound into a drum for storage by a winder.In the cast film extrusion process, the molten materials are extruded through a slot die onto an internally cooled chill roll. Then, it goes through a set of rollers that determine the qualities of the cast film such as thickness. After this step, the cast film is trimmed and rolled.
