Investment casting process, also known as Lost Wax Casting production process. According to this method of production and processing, the products manufactured have high precision, complicated styles, and are basically equivalent to the styles of parts, where production and processing must be carried out. Commodities that are rarely or directly available. For this reason, the Investment Casting process is a type of professional production process. As early as the 1940s, investment casting processing technology has been widely used, such as copper lion products, copper forbidden products, etc., are produced by investment casting processing technology. At present, the processing technology of investment casting processing technology is used in various industries, such as transportation, aerospace, energy, pharmaceuticals, etc., and the rate of progress is rapid. The main ones are Carbon Steel Castings, alloy steel castings, Stainless Steel Castings, iron castings, aluminum castings, Copper Castings and so on.

According to the Precision Casting process, not only Small Casting products can be produced, but also large casting products can be produced. The contour dimensions of investment casting products manufactured in this way are already close to 1.9mm, but the wall thickness is even thinner than 2mm. In addition, the precision casting processing technology continues to develop in the direction of precision. In addition to the linear dimensional tolerances of the casting products, the main parameters of the casting products can reach relatively high geometric dimensional tolerances. The surface roughness of the casting products cast by the precision casting process is also relatively low, which has already been close to Ra0.3um. Due to these advantages of precision casting, it has been widely used in Chinese industry.

In addition, according to this precision casting process, a lot of mechanical processing and manufacturing time can be saved, the entire production and manufacturing cycle time of cast products can be reduced, and the utilization rate of casting raw materials is further improved, and the cost of casting products is also reduced. The quality of the casting products produced is also very high.
