How to solve the problem of scratches in industrial aluminum extrusion processing?

There are about 300 alloys and 1,500 varieties of industrial aluminum profile processing materials in China, which is one of the countries with the most abundant product varieties in the world. Among the many varieties of aluminum processing materials, a large number of international advanced products and national brand-name products have emerged, representing the mainstream direction of the development and application of modern aluminum processing technology in my country. The characteristics of China's aluminum processing technology are that it coexists with backwardness. The technology and equipment of the majority of small and medium-sized enterprises are still at the level of the 1970s and 1990s. As a result, the status quo of my country's aluminum processing industry is large but not strong, and small but not refined, so that the national economy and modern science need high-quality, precise and sharp aluminum materials to still rely on foreign imports. When industrial aluminum extrusion is processed, there is an elimination method: the matching size between the extrusion cylinder and the extrusion pad does not exceed 0.1mm, the working and non-working parts of the extrusion cylinder (the chamfering of the extrusion cylinder inlet) No more than 1.0mm. The working belt of the industrial aluminum extrusion die is smooth and without teeth, and the hardness is guaranteed. The quality of the aluminum rod is qualified, and the industrial aluminum extrusion process is correct. ————The article comes from the Internet.
