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.

or good plasticizing effect,we have different designs of screw and barrel for extruder or 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.
