Precision casting is a casting method in the modern traditional casting process. It can obtain relatively accurate shapes and relatively high casting precision. When designing and manufacturing products, if a better casting method is used to carry out For casting wax, the metal material obtained after a series of castings can obtain a relatively high-precision finished product after sand cleaning, and can be heat-treated or cold-worked according to the needs of the product.

So what are the main advantages of the silica sol precision casting products produced in this way? The application range of precision casting is relatively wide, the production mode is convenient, and it can also produce a large amount of scrap metal and renewable resources, with less consumption. The cost is relatively low, and the comprehensive economic performance is better.

When casting has high dimensional accuracy and high surface finish, the products produced in this way can reduce the workload of mechanical processing, save a lot of machine tools and processing time during processing, and can Significant savings in metal raw materials.

In China it began to apply investment casting to industrial production in the 1950s and 1960s. There are lots of stainless steel casting factories. Since then, precision stainless steel investment casting customized process has been greatly developed and has been widely used in aviation, automobiles, machine tools, ships, internal combustion engines, gas turbines, telecommunication equipment, weapons, medical equipment and cutting tools. China stainless steel investment casting can produce complex castings of various alloys, especially super alloy castings. For example, the blade of a jet engine has a streamlined outline and an inner cavity for cooling, which can hardly be formed by machining processes. The investment casting process can not only achieve mass production and ensure the consistency of castings, but also avoid the stress concentration of residual knife lines after machining.
