As we started as an investment casting foundry, we know details of this metal-forming technique. Investment casting is also known as lost wax casting. Basically, it refers to make a wax pattern formed with a ceramic. Then, melting the wax makes the ceramic empty.

Eventually we get the casting after pouring the metal into the ceramic. In our casting plant, we continue to improving our process and utilizing the newest technology available in our industry.


Water Glass and Silica Sol Investment Casting

Water glass and Silica sol casting make china casting industry special all over the world. The main differences are the surface roughness and the casting price. Most foundries made casting our of water glass process in China 10 years ago. Only few casting foundries change to silica sol process nowadays. However, We keeps both processes and makes more options for our customers.

Water Glass Investment Casting?Method

We use domestic wax and dewax into high temperature water. Most importantly, ceramic mold material is water glass quartz sand that is very cheap locally. Therefore, the surface finish and the accuracy of the casting will not be that good. But it is still weight better than sand casting process.

Silica Sol Investment Casting Method

We use high temperature wax and dewax into flash fire. Meanwhile, ceramic mold material is silica sol zircon sand that is more expensive than quartz sand. Therefore, the surface finish and the accuracy of the casting will be very impressive. Silica sol investment casting is our main production line right now.?
