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: Variablepitch and variable depth, variable pitch and equal depth, variabledepth and equal pitch, and equal depth and pitch.Groove multi-dietype,composite type,mixing type and separating type. |
3.Thematerial of screw: manufactured with high-quality nitroalloysteel,applying the method of hardening& tempering andnitriding,thus it enjoys the characteristics of long working life,wearresistance,and anti-corrosion.Besides, the technique of hard alloyspraying or chrome plating can be usedon the working surface ofscrew,which will make it have better using effectiveness |
