Strictly following the process specifications and operating instructions during the production process is an important guarantee for improving the first-time qualification rate of precision castings.

Investment casting, also known as lost wax casting, includes processes such as wax pressing, wax repair, tree assembly, slurry coating, wax melting, casting of molten metal, and post-treatment. Lost wax casting is the process of using wax to create a wax mold for the parts to be cast, and then coating the mold with mud, which is known as a mud mold.

Lost wax casting is an advanced casting technology, also known as precision casting. Use refractory materials to make the required mold shell, then inject liquid metal into the model, wait for it to cool and solidify, and finally obtain the desired casting.

The suction casting temperature during vacuum suction casting is important. If the temperature is too low, it will cause the lower edge of the casting to be too large, increase the consumption of metal, and also cause slag inclusion in the casting
