Product Description

STEPS INVOLVED IN THE INVESTMENT CASTING PROCESS

  • Create a "pattern" (ie replica) of the part to be cast by injecting wax into the mold. This process is also used for die casting.

  • Compile several potential wax models into a complete assembly called a gate control system or "tree". This form allows molten metal to flow into the cavity at a later stage.

  • The components are immersed in the advanced ceramic slurry (called the investment stage).

  • With the components still wet, add a layer of coarse ceramic particles with a thickness of 10mm.

  • Melt the wax in the dry mold, leaving a thin-walled and hollow ceramic shell.

  • The mold is fired to remove the final wax marks and increase the durability of the final mold. This may require a temperature of 1000°C.

  • Pour the molten metal into the mold that is still heated. The use of heated molds can improve dimensional accuracy, allowing tolerances as low as .076mm.

  • Break or cut the cooled shell mold to expose the casting.

  • Finishing the final part using dressing, grinding, sandblasting, heat treatment and other testing or surface finishing processes
