Process of Investment Casting

0004 TIM图片20191101131333

The process involves several steps, from creating the wax pattern to the final metal casting. The process involves several stages:

  1. Pattern Creation: Develop a wax pattern mirroring the final metal part through methods like injection molding or machining.
  2. Assembly: Group wax patterns on a central sprue for efficient casting.
  3. Ceramic Shell Coating:Apply layers of ceramic slurry to form a mold around the wax tree.
  4. Dewaxing: Heat to remove wax, leaving a cavity in the ceramic mold.
  5. Preheating: Heat the ceramic shell for molten metal introduction.
  6. Metal Pouring: Introduce molten metal into the preheated ceramic shell, filling the wax pattern void.
  7. Cooling:Let the metal cool and solidify within the ceramic shell, replicating the wax pattern.
  8. Shell Removal: Break the shell after metal solidification, revealing and separating individual castings from the sprue.
