Polishing cold heading dies is the key to improving the quality of the cold heading process. The advanced polishing technology we use is a combination of innovative chemical and mechanical methods. For instance, our proprietary chemical polishing formula contains specific additives that accelerate the dissolution of rough surface layers in a controlled manner. This, combined with precision mechanical buffing using specialized tools, ensures a uniform and ultra - smooth finish.
The reduction in surface roughness not only gives the die a mirror - like appearance but also has a profound impact on its performance. By achieving a surface roughness value as low as Ra 0.05μm, the die's wear resistance is enhanced by up to 40%. In a fastener manufacturing line, this means that the die can produce 40% more parts before showing signs of wear.
During cold heading, the improved die surface allows for a 30% reduction in the required forming force. This not only saves energy but also enables the production of more complex part geometries. In the auto parts industry, for components like transmission gears, the dimensional accuracy improvement leads to a significant reduction in noise during operation.
Our professional technical team consists of engineers with an average of 15 years of experience in die polishing. They continuously research and develop new techniques to adapt to different die materials and production requirements. With strict quality control that includes in - line monitoring during the polishing process and comprehensive final inspections, and our 24/7 after - sales service, we are dedicated to maximizing customer satisfaction and industry competitiveness.
