Used for thin shell precision casting, which can make the shell strong and the casting smooth.

The advantage of silica sol precision casting in the production process is that the investment casting has very high dimensional accuracy and the surface finish of the product is very high. The use of silica sol precision casting can reduce the machining work to a certain extent.

     Silica sol precision casting can leave a small machining allowance on the parts with higher requirements. During the processing process, some castings only leave a polishing allowance and grinding, and can be used without mechanical processing.

      The use of silica sol precision casting can save machine tool equipment and processing hours to a certain extent, which can greatly save metal raw materials. Another advantage of investment casting is that it can process complex castings of various alloys.

     The processing technology of silica sol precision casting is relatively complex and cannot be controlled. It consumes a lot of material during the processing. Therefore, this processing method is very suitable for processing small parts that require relatively high precision and have complex shapes that are difficult to process.

     One of the processes in the production process of silica sol precision casting is to make investment molds. During the use process, it is mainly used to form the model of the cavity in the refractory shell, so castings with relatively high dimensional accuracy and surface finish can be obtained.

     The investment mold of silica sol precision casting itself should have high dimensional accuracy and surface smoothness, and the performance of the mold itself should also make subsequent processes such as molding the shell as simple and easy as possible.
