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
