Casting Metals

Melt and pour these alloys into molds to create metal parts and prototypes.
Zinc alloy is nonshrinking and corrosion resistant. Parts cast from this material are easy to machine.

No-Residue Mold-Release Lubricants

Also known as paintable mold-release lubricants, these lubricants don’t leave a residue, so you can paint or finish the molded part without the need to clean it. Apply them to molds before casting so you can easily remove cast parts and prevent sticking, stretching, and tearing. Lubricants with zinc resist dust and can be used with ceramics.
