Basic mold making and casting guide/instructions

Step 1: Prepare your item to be molded

• Inspect item to be molded and ensure that it is clean and free from dirt, grease, oil, scratches, or blemishes.

• Fasten your item to a piece of non-porous wood or plastic using hot melt or super glue. If your item is not completely flat for gluing, you can lightly embed the item in synthetic clay as shown here. This will act as the base for molding.

Step 2: Build your mold box

• Find a non-porous material to use for mold box. Commonly used items are old plastic containers, wood, PVC tubing, or plastic sheeting.

• Build your mold box 1⁄4” to 1⁄2” larger than your item. Making it too large will waste your silicone molding rubber.

• Seal the mold box to the base using clay, hot melt glue, or tape. Also, seal any seams on the mold box were silicone may leak out.
