Investment Casting Process:

Wax die making: Our wax tooling is made of Aluminum which is easy for machining and fast for cooling, at the same time, light for handling. Wax injection: Filling the entire mould with molten wax, and let it cool, until a desired wax pattern is shaped and harden. Assemble the wax patterns: The wax patterns are welded to a runner system by a heated metal tool according to a certain pattern cluster(tree) design. Investment: The ceramic mould, known as the investment, is produced by three repeating steps: coating, stuccoing, and hardening. The first step involves dipping the cluster into a slurry of fine refractory material and then letting any excess drain off, so a uniform surface is produced. This fine material is used first to give a smooth surface finish and reproduce fine details. In the second step, the cluster is stuccoed with a coarse ceramic particle, by dipping it into a fluidised barrel, placing it in a rainfall-sander. Finally, the coating is allowed to harden. Dewax: The investment is then allowed to completely dry, which can take 16 to 48 hours. It is then turned upside-down and placed in a autoclave to melt out and/or vaporize the wax. Burnout & preheating: The mold is then subjected to a burnout, which heats the mold to remove any moisture and residual wax, and to sinter the mold. The mold is preheated to allow the metal to stay liquid longer to fill any details and to increase dimensional accuracy. Pouring: The investment mold is then placed cup-upwards into a tub filled with sand and be poured. After treatment: The shell is then hammered, media blasted, vibrated, waterjeted, or chemically dissolved to release the casting. Further actions like weld repairing,grinding, shot blasting,CNC machining, electro plating will be taken to get a final cleaned precision casting part.
