| 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, variabledepth andequal pitch, and equal depth and pitch.Groove multi-dietype,compositetype,mixing type and separating type. |
3.The material of screw: manufactured with high-quality nitroalloysteel,applying the method of hardening& tempering and nitriding,thus it enjoys the characteristics of long working life,wear resistance,andanti-corrosion.Besides, the technique of hard alloyspraying or chromeplating can be usedon the working surface of screw,which will make it has better using effectiveness |
