Mold spring surface treatment technology method:
The current mold is the main process equipment for industrial production. The development of modern industrial products and the improvement of the technical level depend largely on the development level of the mold industry. Since the Second World War, the increase in automation has led to the rapid development of foreign molds. Although my country is a big country in mold production, it is not a strong country in mold manufacturing. For springs that match the mold, this detail is also the key to achieving quality. It affects the performance of the entire mold.
The surface of the spring is identified by various paint layers, such as yellow paint for light and small loads; blue paint for light loads; red paint for medium loads; coffee paint for extremely heavy loads;
Performance analysis: A good paint layer to match the surface treatment of the spring can be described as two birds with one stone. The color is used to identify various technical parameters, which is convenient for industrial production and operation, and the anti-corrosion performance of the spring surface can be better guaranteed.
At present, the main manufacturers that successfully use the above methods are many foreign manufacturers, such as Japan’s Dongfa Company.
In China, only a small number of manufacturers have effectively visited. At present, it is mainly due to some fixed technical requirements, such as the use of imported materials to reach foreign levels, but there is an obvious gap in the surface treatment effect of the entire spring.
Generally, manual painting is used in China, and the appearance will appear sagging, leaking, poor combination, and poor rust resistance. The limitations of its own process cause a large number of products to be stripped and reworked.
