A multi-step process that produces near-net shape precision casting parts. The process begins with the creation of patterns. These are then used to create moulds that are filled with molten metal to create the part. Secondary processing, such as machining, welding or painting can also be done. The process uses different machines such as furnace, injection, blasting, tumbling, cutting, grinding, etc. The process involves mainly the following steps
Investment casting, also known as lost wax casting, can produce steel casting parts with good surface quality and high accuracy in dimensions, and it is used to produce large numbers of high quality castings. Investment casting uses a wax copy of the component, dipped (invested) in a ceramic slurry to produce a ceramic mold. The wax is then removed to leave the ceramic shell, into which molten metal is poured.
Patterns of the castings to be made are molded by injection of a special wax into a metal die. Cores of pre-formed ceramic may be incorporated into the wax patterns as they are molded. The patterns are assembled into a cluster (often comprising tens or even hundreds of patterns) around a wax runner system. The ‘tree’ of patterns is then coated with 8-10 layers of a refractory material, each layer being dried or chemically cured before the next layer is applied.
The assembly is heated to remove the wax, then fired at high temperature to bond the refractory mold strongly. The hot mold is casted and when cooled the mold material is removed by impact, vibration, grit blasting, high pressure water blasting or chemical dissolution leaving the castings, which are then removed from the runner system.
Our investment casting services are present in a wide variety of products, including high quality, top performance industrial parts. We typically serve the following industries:
