Product Description



Qunying is one of the best machinery supplier in China. We cooperate with many machine factories. Waiting for your cooperate with us,you best choice!


 


For good plasticizing effect,we have different designs of screw and barrel for injection machine to meet customer's demand.Our factory manufactures with high-quality material, 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.


 


Extruder screw diameter: 15 - 300 MM


LD for extruder screw: 1:5 - 1:65


Extruder barrel OD: 20-500 MM
