Description

screw and barrel for film blowing machine 
professional manufactory 
long work life 
anti corrosion 
alloy bimetallic steel 
 

Technological Process:

Blanking→Rough Machining→Quenching & Tempering →Semi Finishing Machining→Finished Product→Detecting→Nitring/Alloy Processed →Finish Machining

For good plasticizing effect, we have different design of screw barrel to meet customer's demand:

gradual type, mutant type, wave type, barrier type, double screen type, shunt type, separation type, exhaust type, pin type, double-head type, multi head type etc.

Single extruder screw barrel for film blowing extruder machine

have following features :

The screw adopt barrier type mixing zone.

The barrel feeding zone is groove feed bush and made of hard alloy.

It results in higher output rates, homogeneous plasticizing and less material slippage.

Bi-metallic screw&barrel can be provided for two-three times more lifespan than nitrided screw&barrel.

Features:

Easy operation

Optimum performance

Durable

Low power consumption

Corrosion resistance

Material:

Alloy-steel of high-quality
