Past Issues

The 4 Main Departments in Investment Casting

An Investment Casting Facility can be broken into 4 major departments:


  • Wax
  • Shell
  • Foundry
  • Finishing

When can we see the actual casting?

In the last issue we discussed pouring the molten metal into our ceramic shell. Once the metal has solidified, it is now time to see what our casting looks like. We need to remove the ceramic shell, cut the part off of our runner system and grind off the gate which is also part of the metal delivery system.
