Jinsheng Bimetallic Plastic Machinery Factory was established in 2004. It was developed as a large-scale and comprehensive company specializing in manufacturing the kinds of Screws and Barrels in Zhoushan.such as bimetallic barrel & screw ,conical twin screws & barrels ,parallel twin screws & barrels,single screw &barrel , rubber screw & barrel ,planetary screw & barrel and  components apply for injection molding machine and extruder machine .

For the material of screw and barrel we usually used: #45 steel,40Cr,38CRMOALA, 42CrMo,SKD11,SKD61 and high temperture ALLOY etc.

Jinsheng team aim at providing the best services to customers which include providing short lead time, best price and best after sales services. These allow us to create good relationship with customer. Moreover, our engineering department can design special screw and barrel design for some special plastic material such as HDPE, LDPE. This special design can provide high output with low energy consumption. With our great effort on product quality and services, we win a lot of support from different customers which from machinery and plastics field. we will make improvement continuously so as to win customer support from different countries.

Due to our high quality products and outstanding customer service, we have gained a global sales network reaching America, Germany, Brazil, Russia, Ukraine, India, Pakistan,Egpyt,Argentina and some other countries and regions.
