Bimetallic barrel

Since its establishment in 1990, Zhoushan microwave screw machinery Co., LTD has been committed to the production and research of plastic machinery, and has introduced advanced foreign screw machinery technology and processes. As a diversified large-scale professional production base in China, we integrate precision screw barrels and mechanical processing, focusing on the high-end market. Our products are mainly exported to the United States, Germany, Dubai, Vietnam, Thailand and other countries or regions, and have established cooperative relations with many plastic production and construction machinery factory customers, becoming their important supplier of mechanical parts in China.

In the field of plastic machinery, Bimetallic barrel is one of our core products, which is widely used in automobile manufacturing, home appliance production, packaging materials, medical equipment, electronic communications and other industries. Through precise CNC machining, we ensure that the matching accuracy between the screw and the barrel reaches the micron level, reduce friction resistance during operation, improve plasticization quality, and reduce energy consumption. This high-precision processing technology improves production efficiency, meets the requirements of modern industrial environmental protection and energy saving, and helps enterprises achieve sustainable development.

Bimetallic barrel adopts a dual alloy composite structure, with high-strength and high-wear-resistant alloy materials used for the outer layer and alloys with excellent thermal conductivity for the inner layer. This structure can resist wear during plastic processing, extend the service life of the barrel, reduce replacement frequency, and reduce maintenance costs. , combined with the optimized hot runner design, it can achieve rapid and uniform heating and plasticization of the plastic melt, shorten the production cycle, and improve production efficiency. The bimetallic barrel has good adaptability to a variety of plastic materials and meets the diversified needs of injection molding products in different industries.

The Bimetallic barrel provided by Zhoushan microwave screw machinery Co., LTD is plated with a 2-3mm wear-resistant and corrosion-resistant coating on the inner wall of the barrel, and a high-temperature resistant alloy is also used, which greatly improves the service life compared with ordinary nitriding barrels. It is especially suitable for processing special plastics such as engineering plastics, fluoroplastics, polysulfones, PPO, etc., and the advantages of bimetallic are particularly obvious. We can choose the right screw according to different uses, using different alloys and welding methods, such as ordinary nitriding screws (SACM645), top spray welding bimetallic alloys, full-coverage tungsten steel screws, full-hard series NPT1, NPT2, NOT3, and surface-generated ceramic films, diamond films, etc.

In terms of barrels, we offer a variety of options such as ordinary nitriding, inner bore centrifugal casting alloy and full hard inner sleeve series. After strict heat treatment and surface treatment processes, Bimetallic barrel has extremely high dimensional stability and corrosion resistance, ensuring long-term stable operation of the equipment and reducing production interruptions caused by equipment failure.

Zhoushan microwave screw machinery Co., LTD also produces WB-WE series planetary screws, planetary barrels and planetary extruders; SJS series Conical Twin Screw, double barrels and twin screw plastic extruders; SJ series single screw, single barrel and single screw plastic extruder; Pearl cotton screw barrels and various tubes, sheets and profile production lines. These products complement the Bimetallic barrel and provide customers with one-stop services from pre-sales consultation, solution design, installation and commissioning to after-sales maintenance, ensuring that every customer can enjoy a professional and considerate service experience.
