Features Specifications: Screw
Instructions for Screw:
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 nitroalloysteel, applying the method of hardening and tempering andnitriding,thus it enjoys the characteristics of long working life, wearresistance,and anti corrosion. Besides, the technique of hard alloyspraying orchrome plating can be used on the working surface of screw,which willmake it have better using effectiveness
