ZHOUSHAN JINJIA plastics machinery Co.Ltd is one of the largest bimetallic screw and barrel manufacturers in China.With the intergration of new technology research, manufacturing and sale, we unceasingly introduce the high-technology and devote to research and development the current leading international super-hard bimetallic screw and barrel, which by the cobalt tungsten carbide take substrate with the characteristic of high hard-wearing, high corrosion resistance and high hardness.Especially the nickel-based Co-Cr bimetal twin barrel has got the nation patent(Patent number:ZL2005201***31.9).We have the unique perspectives for a serious of engineering plastics, specially in halogen flame retardant plastic high glass-plastic, magnetic plastic, high calcium powder plastic, powder metallurgy, etc.

In the developed countries of Europe, there are more than 90% plastic machinery companies using the bimetal barrel and screw.It is not only improving the grade of the entire injection molding machine, but also providing customers with high quality products.Using bimetal barrel and screw will be the famous machinery companies ' best choice in future.

With the advanced high-temperature and high-speed centrifugal bimetal casting furnace, screw cladding processing equipment and technology, and the word's top twin-metal alloy composite barrel manufacturing equipment,intelligent Lane's hardness and alloy layer device detection equipment, and dedicated bimetal processing lathe, using a number of fabricating machinery and manufacturing technique such as extra hard cutlery and special-purpose bimetal deep hole grinding from Germany, we turn out producing bimetal barrel and screws which represent the world highest level.
