Development of Silica Sol Investment Casting in China

The development trend of silica sol precision casting in China should be relatively late. In the process of developing the products, it is required that the precision of the processing technology is very strong. The silica sol precision casting must strengthen the understanding of the product process in the basic theory and practice, and continue to supplement its basic technical knowledge.

The silica sol precision casting has rich and colorful social experience. When it is used, the whole silica sol precision casting process will be clarified, and a more powerful classic will be cast. In the process of supplement, its foam model needs to be dissolved through its vaporization, which will produce many small molecule water vapor and foam ash.

To some extent, this substance will have an impact on people. In daily work, operators must strictly follow their operation guidelines. No matter what safety protection objects are used in the operation process or for assistance, they must carry out according to the requirements. During the manufacturing process, they must flexibly use the operation process.

For some complicated thick wall castings, in order to effectively improve the air permeability of the molding shell of professional silica sol precision casting, the air vent can be set at the high point when it is very possible, so that the gating system software can be effectively set to avoid pouring entrapment.

During the use of silica sol precision casting, the pouring temperature shall be moderately increased, the distance between the ladle nozzle and the pouring cup shall be reduced as much as possible, and the pouring rate shall be effectively reduced, which can enable the molten metal to fill the mold stably.

The shell culture of silica sol precision casting should be comprehensive, and the use process should have sufficient temperature, so as to ensure that the shell culture of precision casting can be thoroughly burned, so that the gaseous chemical substances of new products can be sufficiently removed, and the real shell culture should be gray white or light gray, and there should be no black spots.
