Casting Techniques:
Lost-wax casting: Starting with a wax pattern, shop users make molds in gypsum-based investment. Molds are heat-treated in a kiln and then cast in metal with a vacuum-casting machine. Picture: \Main_page_pix\lost_wax_pour.jpg (Link to lost-wax casting class listing)
Sand-casting: Durable patterns are pressed into oil-bonded sand to make a mold that can be cast in metal with no heat treatment. (Link to sand-casting class listing)
Rubber molding: Durable, nonporous patterns are molded in heat-vulcanized rubber to be reproduced in wax with a pressure-injector.
Tools:
Vacuum caster: This machine pulls air through the pores of a lost-wax mold to draw the molten metal into fine detail during casting. RED tool: Tool-testing required. Link to: Vacuum Caster Tool Resource Page) Located under the hood against the south wall.
Sentry Kiln: For heat-teating and burn-out of lost-wax molds. RED tool: Tool-testing required. Link to: Sentry Kiln Tool Resource Page Programmable controller, temp limit: 1350 F.
Electromelt furnace: For melting metals to cast. RED tool: Tool testing required. Removable graphite crucibles for different metals, including gold, silver, argentium (Ag-Ge), bronze, brass. Temperature limit: 2000 F. Link to: Electromelt Tool Resource Page
Safety:
There are significant hazards in this lab. Molten metal can cause very severe, crippling burns. Eye protection, closed-toe shoes, dust masks, hot gloves, aprons, must be worn at various times when tools are in use. Dust contains crystalline silica Dust masks required. Precautions are similar to those for welding. Link to: Casting Shop Safety]
