Lost wax casting is one kind of casting method for manufacturing metal products, which refers to precision casting.Modern precision casting is called investment precision casting. Lost-wax precision casting is generally used for small castings.

Lost wax casting process is as follows:Press liquid paraffin wax into briquetting→ take out wax pattern→ fit gate→ paint and make shell→ melt wax pattern→ bake mold shell→pour molten metal→take out castings →clean pouting gate and burr → test and put it in storage.

Common castings made by lost wax precision castings are numerous, such as lost wax casting steel, one of the advantages the casting is its flexible design, and designers have the greatest freedom of choice the casting shapes and sizes. The metallurgical manufacturing made by the lost wax casting steel has strong adaptability and variability, engineering and high reliability.

Henan Metals & Minerals could use three ways to produce the investment precision castings / lost wax precision castings:

1.The sodium silicate process for large- scale parts

2. The silicon sol process for high dimension precision and high finish parts

3.Compound technology are somewhere in between

Referred to the weight of investment castings, Henan Metals & Minerals can supply from 10 g to 130 kg.

Referred to the material of investment casting,Henan Metals & Minerals can make of carbon steel, alloy steel and stainless steel.
