Key points and problems of aluminum profile extrusion press machine plant line

Issue Time:2022/06/02
With China's large-scale infrastructure investment and the rapid progress of industrialization, the output value and consumption of the whole profession of aluminum profile extrusion press machine plant line have increased rapidly, and China has also become a larger aluminum profile production base and consumer market in the world. After nearly 10 years of rapid growth, China's aluminum profile profession has entered a new stage of development and shown many new development trends. Moreover, with the building, transportation, industry, automobile, solar energy and led processing, the requirements for high precision and high performance of aluminum alloy kneading products accumulate day by day, and the profile section shapes are complicated and diversified. There are many deficiencies in designing according to conventional and common methods. Therefore, in order to obtain high-quality profiles, we must constantly learn, accumulate, transform and innovate in production and life.
The size and error of kneading parts are determined by the mold, kneading equipment and other relevant process factors. The aluminum profile extrusion press machine plant line is greatly affected by the change of mold size, and the reasons that affect the change of mold size include the elastic deformation of the mold, the temperature rise of the mold, the material of the mold, the manufacturing accuracy of the mold and the wear of the mold.
For the tonnage selection of aluminum profile extrusion press machine plant line, the kneading ratio indicates the difficulty and ease of kneading by the mold. Generally speaking, the kneading ratio between 10 and 150 is applicable. If the kneading ratio is lower than 10, the mechanical performance of the product is low; On the contrary, the kneading ratio is too high, and the product is simple with defects such as rough surface or angular error. It is often recommended that the kneading ratio of solid profile is about 30, and that of hollow profile is about 45.
