I chose a bangle bracelet that was pretty complicated with holes throughout to demonstrate how you can make complex objects with a simple mold.

To start making your resin bracelet:

Hot glue the original bracelet, or master, to the bottom of the container. Melt the ComposiMold in your microwave or use a double boiler to heat. Pour the ComposiMold over and around the bracelet. Use a paperclip, piece of wire, or toothpick to pull away any bubbles from the crevices in the bracelet. We also recommend spraying the part with Bubble Buster to reduce bubbles from sticking to the part.

And let the mold cool to solidify. In the freezer, this mold would take a couple of hours to solidify into a nice rubber.

Now, cut out the original master object from the mold box. We do that by cutting away the plastic container as that’s typically easiest.

Cut along the bottom of the mold and cut the holes within the bracelet to pull out the original.

This hole between the mold makes this a pretty complicated shape, but still doable just by cutting.

Pouring the Resin into the Bracelet Mold

We’re using ComposiCast White resin with a little black colorant to make a gray bracelet. Mix in a few drops of colorant into the ComposiCast.Mix the two parts of resin together 50% of each. It’s extremely flexible so if you accidently use too much or too little of one, you should be fine. Try to err on the side of more resin and less hardener. More Part A and less Part B. Pour the resin into the mold cavity and let it cure overnight. 10 hours later, you are ready to pull out the duplicated casting.

Cleaning up the Casting

Clean up the casting by cutting off any extra resin, sanding away any blemishes, and you are ready to go.

This is a challenging mold, probably about a level 4 out of 5, 5 being the hardest, so start simple and work to more complex molds. And you can do that all with the same ComposiMold, since it is re-usable. With ComposiMold, you can make dozens of great unique molds with the same molding material.
