Process of 17-4 Stainless Steel Casting

The investment casting process has been used to creat stainless steel castings for a long history, and such casting technic can creat 17-4 ph stainless steel castings in accurate dimensions and good surface finish. The steps of 17-4 ph stainless steel castings are given below:

  • Making a mold according to 3d file.
  • Filling the mold with wax to creat wax patterns, inspect and modify the patterns if there is any defect.
  • Weld the wax patterns to form a assembly.
  • Dipping the wax into ceramic slurry to form a shell.
  • Heating the ceramic shell to remove the wax.
  • Pouring the molten shell.
  • Breaking off the shell, and shot blasting or operate other surface finishing.
