What is Investment Casting

Investment Casting is a precision casting process, also known as the “lost wax casting”. It is known for its ability to produce metal castings with extremely complex shapes, high dimensional accuracy, and good surface finish, especially for high melting point alloys or complex parts that are difficult to machine by other methods.

The Process of Investment Casting

The main process of investment casting can be divided into the following six steps:

  1. Wax Pattern Production: Create a metal mold based on the final part shape, then inject low-melting-point wax under pressure into the mold to obtain a precise wax pattern.
  1. Shell Building (Investment): The wax model is repeatedly immersed in the ceramic slurry, and after each dipping, a layer of fine sand made of refractory material is sprinkled, and this process is repeated several times until a ceramic shell with sufficient thickness (usually 5-15mm) and sufficient strength is formed on the surface of the wax mold
  2. Dewaxing (Wax Removal / Lost-Wax Process): After the ceramic shell is dried and hardened, it is placed in a high-temperature steam oven to allow the wax mold inside to melt and flow out, which is also the origin of the name “lost wax casting”.
  3. Shell Sintering: Place the dewaxed ceramic shell into a high-temperature furnace for firing to enhance its strength.
  4. Fonderie: Pour the molten metal into the cavity of the shell mold.
  5. Shell Removal & Post-Processing: After the metal is completely solidified, the outer layer of ceramic shell is removed by mechanical vibration, sandblasting, etc. The gating hole is then cut off, and subsequent processes such as heat treatment, sandblasting, polishing, machining, and surface treatment are carried out as required.
