Those who work in the foundry field are very clear. Among them, the warm wax silica sol precision casting is also called investment precision casting. Such a manufacturing process is a casting process with little or no drilling. Silica sol At the same time, precision casting is also a very professional production process in the field of casting.
Precision casting is not only suitable for casting of various types and metals, but also the dimensional accuracy and appearance quality of castings produced by such technical processing techniques are much higher than other casting methods, and even Other casting methods are difficult to cast complex, difficult to produce and process and heat-resistant castings. If you want to produce products with simple design and appearance, and the size is not very large, you can first choose aluminum profiles or cast carbon steel for production and processing of products with high dimensional accuracy.
The characteristics of the application of steel molds are the low price of raw materials, the defect is that the molds are relatively heavy, and there are certain regulations for the production and processing of knives. It is more laborious for some manual production. The appearance is complicated, the precision requirements are high, and the product size is relatively large, you can consider the application of silica sol precision casting. high. Naturally, the cost of raw materials is slightly higher. The appearance is complicated, the size of the silica sol precision casting casting itself is not very large, and the precision requirements are not very high. You can consider the use of aluminum frame tin and bismuth to make the mold. The net weight of the tin-bismuth mold is very heavy. Due to the presence of bismuth, it takes less time to make more complicated molds and saves the cost of machining.
