What is resin plastic molding?


Plastic molding is the reusable plastic molds used to create molded items such as resin jewelry, plaques, souvenirs, drawer handles, custom tiles, and sun catchers. It is important to note that molds used for food items must be FDA-approved “food-safe” plastic molds. The unique and incredibly easy resin jewelry and crafts you’ll be able to fashion using a variety of resins, transparent and opaque dyes, and artifacts like small charms or flowers to embed are endless—limited only by your time and imagination.

What kinds of plastic molding are available for casting resin?

These durable reusable molds are available in self-releasing polypropylene and polyethylene plastic molding, used especially with clear polyester resin and casting epoxy.

TIP: Though relatively self-releasing, plastic molding will last longer for more castings if it is conditioned and cleaned with a mold release/conditioner with each. Castin’Craft Mold Release/Conditioner is often used by experienced resin crafters.

How do I make a casting with plastic molding?

It is simple to cast your own jewelry with a plastic mold and resin.

1: Protect your work area with freezer or waxed paper.

2: Spray the clean mold with mold release/conditioner.

3: Place the mold on a level surface, and fill the mold cavities to just below the top with resin.

4: Once cured, simply flip the plastic molding tray over, and press the center of each piece to release it, flexing the mold if necessary.
