The bimetallic barrel for single screw is a kind of barrel moulding 2-3mm thick alloy coat on the barrel inner wall which has excellent corrosion resistance, abrasion resistance and high working temperature. And its useful service life is greatly improved contrast to the common nitrided cylinder. Bimetal has more obvious advantages when processing special plastics to enhance the abrasion life, such as engineering plastic, fluorine plastics, PPO and etc.

The company product's single/twin screw, uses special alloy powders being sprayed and welded on the screw's ridge, and uses different alloys and welding methods for the screw of different functions.

Our main office and factory are located in Zhoushan, ZheJiang Province in China. Zhoushan is a very beautiful tourist place

which is famous for it's Buddism culture. Not like the other place with severe air pollution in China, we got the fresh air and blue

sky which are very inhabitable for living. We have over 10 year's experience manufacturing all kinds of screws and barrels. We

have dedicated technicians who are very experience in making those screws and barrels.

And our factory is very close to Ningbo Seaport and Shanghai Seaport which are the two major seaports in China. Such kind of

geographical advantage provided us a huge convinience to export our products.

Our products are mainly applied in injection moulding machines, plastic extrusion machines and rubber extrusion machine.

We are both the factory and foreign trade company so that we can provide the customers a very competitive price. We sincerely

welcome all kinds of customers all over the world to negotiate with us.

As a company, it's true that we are making money, but we are are also more focusing on how to make our customer's

granted. Cause we know the one who made the customers happiest, earning the most money.
