Introduction

Varies polymer has different requirement for screw barrel design to suit with your varies polymer processing, we have engineer with more than decade of experience in screw designing & customized services.


Life-time matters : A good functioning screw barrel can not only guarantee proper running of plastic injection, but also with long working period, can massively save your changing time and stop-machine cost.


It’s a plastic expansion time, every day with new polymer coming into market, and additives too, some very abrasive & corrosive, we offer tailor screws barrels with different steel & treatment to meet your request, highest can process up to 50% glass fiber filling plastic.


For good plasticizing effect,we have different designs of screw and barrel for injection 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.
