Metal Casting

Metal Casting- Main Page

Welcome to the metal casting shop!

We have a vacuum casting setup with a kiln, vent hood for investment mixing, and an oxy-propane torch and Electro-melt for metal melting. To use any of these tools, you must be signed off by the shop lead or a tool tester!

Shop Rules

Tool Testing

Currently, we are asking new users to take a class to learn proper operation of the tools. The class teaches safe operation of shop tools, but does NOT certify you to use the shop independently.

  • To get signed off on investing, you will need to complete one investment cycle safely with shop lead/tool tester present.
  • To get signed off on torch casting or Electromelt casting, you will need to cast three times safely with the shop lead or a tool tester, without needing any feedback from the tester at least one of those times.

You can email the shop lead (casting-lead -at- to arrange tool testing.

As of March 2019, we're requiring re-certification on the tools due to there being no previous list of signed-off individuals. If and only if you have previously taken a casting class at the Asylum, this will take the form of doing one cycle of investing + casting with the shop lead present to ensure proper safety procedures and tool usage. Email the casting lead  (casting-lead -at- to set up a time (usually during office hours) to get signed off.
