Features Specifications: Screw
1.We are a professional company specialized in manufacturing many types of screw,the barrel can be applied on all types of extruder machine,rubber hot-feeding extruder,rubber cold-feeding extruder,pin barrel cold feed extruder,plastic extruder and injection molding machine 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 alloysteel,applying the method of hardening& 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 usedon the working surface of screw,which will make it have better using effectiveness |
