Brife description of investment casting process:

 

  • Wax mold 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: Feeding the entire mould with molten wax, and 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.

Competitive Advantage:

 

Winntington has strong technical support and full range of casting facilities and testing instruments to cater the growing investment casting business.

 

Investment casting is an industrial process based on and also called lost-wax casting, one of the oldest known metal-forming techniques.The castings allow the production of components with accuracy, repeatability, versatility and integrity in a variety of metals and high-performance alloys. 

 

Investment casting is generally more expensive per unit than die casting or sand casting, but has lower equipment costs. It can produce complicated shapes that would be difficult or impossible with die casting, yet like that process, it requires little surface finishing and only minor machining.
