Precision casting machinery industry is growing rapidly
According to relevant reports, during the “10th Five-Year Plan” and “Eleventh Five-Year Plan” period, the average annual growth rate of the main economic indicators of the precision casting machinery industry is above 30%, which is higher than the average growth rate of machine tools and the whole industry, especially the faster growth of profits. The average annual profit increased by 46%, while maintaining a high level of market sales. In addition, the resin sand casting complete equipment can basically meet the domestic market demand, changing the situation that relied mainly on imports in the past; it has been able to produce a higher level of automatic casting production line, which can partially replace the imported level, and partially solve the car engine. Castings such as cylinders and cylinder heads must also be imported; casting machines such as high-level automatic core making machines, automatic casting cleaning machines, automatic sand processing machines, large-scale automatic die-casting machines, and precision casting equipment can be manufactured in China. . It should be said that the product level of the precision casting machinery industry during the "10th Five-Year Plan" period has been greatly improved, laying a good foundation for the further development of China's foundry machinery industry in the future.
In recent years, with the continuous improvement of the industrial chain of China's precision casting parts industry and the continuous improvement of the technical level, the downstream demand field has shown an increasing demand for precision casting parts. However, the traditional precision casting production process still has many problems, which is plagued by a large number of precision casting manufacturers. In this market background, with its years of experience in the foundry industry, using its high-performance light-curing 3D printing equipment, it has launched a new Quick Casting application solution for integrated systems. It can effectively solve the pain point problem in the traditional precision casting process, and at the same time guarantee the production of high quality castings.
Ma Tian loose iron stainless steel: This kind of stainless steel body-centered cubic structure (BCC) can attract the magnet and get it from the Aostian temperature, which has the best corrosion resistance, but the material is hard and brittle, then it is returned. Fire can increase ductility, but corrosion resistance will decrease, especially tempering between 450 and 650 degrees Celsius, causing carbon atoms in the crystal lattice gap to diffuse and chromium to form a network of chromium carbide causing adjacent areas. The consumption of chrome element lowers the chromium content, prevents the formation of a protective film, and loses corrosion resistance, so special care is required. The following are the heat treatment temperatures for various granulated iron-based stainless steels.
Precision casting is a casting method compared to conventional casting processes. It achieves relatively accurate shape and high casting accuracy. It is more common to first make an electrode of the desired blank (with little or no margin left) and then use the electrode to etch the mold body to form a cavity. The wax is then cast by casting to obtain the original wax pattern. A layer of high temperature resistant liquid sand is applied to the wax pattern. After obtaining a sufficient thickness, it is air-dried and then heated to dissolve the inner wax mold to obtain a cavity conforming to the desired blank. The cast iron water is poured into the cavity, and after the curing, the outer casing is peeled off to obtain a precisely manufactured product.
