Renovation process of screw injection molding machine in Huzhou :
1. The twisted screw should be considered according to the actual inner diameter of the barrel, and the outer diameter deviation of the new screw should be manufactured according to the normal clearance with the barrel.
2. After the thread surface of the reduced screw diameter is treated, the wear-resistant tungsten carbide alloy is thermally sprayed, and then ground to size.
3. Overlay welding of wear-resistant tungsten carbide alloy on the threaded part of the worn screw. According to the degree of screw wear, surfacing is 1 ~ 2mm thick, and then the screw is ground to size. This wear-resistant tungsten carbide alloy is composed of C, Cr, Vi, Co, W, and B materials, which increases the screw's ability to resist wear and corrosion.
4. Repair the bottom diameter of the screw as a method of electroplating hard chrome. Chromium is also a wear-resistant and corrosion-resistant metal, but the hard chrome layer is relatively easy to fall off.
Huzhou production injection molding machine screw
Our company is a professional manufacturer of alloy barrel screws . Complete product specifications, mainly used for supporting the injection molding machine, extruder, rubber machine, chemical fiber machine and other machines.
With the continuous development of the plastics industry, a variety of new plastic materials continue to come out. Higher requirements are imposed on the working conditions of the barrel and screw of the main components of the extruder and injection molding machine. Corrosion and wear are the only reasons for the failure of screw barrels. After a long period of continuous innovation, our company has absorbed the advanced technology of screw manufacturing at home and abroad, and has successfully developed the manufacturing technology of full hard series screw and double alloy barrels . The alloy barrel screw produced has better performance and can better meet customer requirements.
At the same time, our company has a complete set of management systems and sophisticated manufacturing equipment to ensure that the quality of products is constantly improving. And strictly in accordance with the national plastic machinery industry standards, the product has the advantages of high accuracy, no deformation, good wear resistance, strong corrosion resistance and other advantages. Over the years, the company's products have been exported to Southeast Asia, Europe and many other countries in batches. We provide complete machine supporting services for dozens of domestic customers. After long-term use by users, they believe that the prices are reasonable and the quality is comparable to imported products.
Zhoushan Zhousheng Bimetal Machinery Co., Ltd. is willing to provide customers with low-cost and high-quality products. Welcome customers at home and abroad to create business together
