Instructions for our Screw&Barrel:

1.We are a professional company specialized in manufacturing many types of screw, the barrel can be applied on all types of injection moulding machine,rubber hot-feeding extruder, rubber cold-feeding extruder, pin barrel cold feed extruder, plastic extruder with different specifications.
2.The models of screw include:

Variable pitch and variable depth, variable pitch and equal depth, variable depth and equal pitch, and equal depth and pitch.

Groove multi-die type, composite type, mixing type and separating type.

3. The material of screw: manufactured with high-quality nitro alloy steel, applying the method of hardening and tempering and nitriding, thus it enjoys the characteristics of long working life, wear resistance, and anti corrosion. Besides, the technique of hard alloy spraying or chrome plating can be used on the working surface of screw, which will make it have better using effectiveness.
