Bimetallic Screw Barrel Suppliers and Manufacturers

Ningbo Superior Machinery and over 30-year-old factory with ISO 9001:2008 certificated, manufacturing screws, barrels for injection and extrusion processing. Specifications of our Ni-based bimetallic barrel: Basic Material for body: superior pre-hardening material 4140 Alloy powder: Nickle-based self-melting alloy powder from American Wall Colmonoy Corporation Processing: vacuum sintering cladding ( we're the first and unique Chinese factory applying this technology to barrel production since 2009!) Hardness: 56-60 HRC Service life: 3~6 times than bimetallic barrels processed by high temperature centrifugal casting Application: halogen-free plastic, the high abrasion, corrosion materials adding high fibre, carbon fiber, mineral fiber, ceramic, magnetic powder, metal powder etc. Advantage: more stable molecular structure, higher density of the alloy power than common bimetallic barrels.

APPLICATION A Commonly used for adding acid plastic with GF less than 30% B For transparent material and color mixing material TECHNICAL PARAMETER A Using 38CrMoAlA high quality alloy structural steel, the top spray-welded nickel based alloy powder. Alloy thickness1.5mm. Hardness HRC 53-56 B 42CrMo alloy structural steel sprayed with nickel-base alloy powder.Alloy thickness1.5mm,Chrome plating thickness 0.03-0.05mm.

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.
