Basic Instructions for Mold Making
Make your flexible rubber molds with ComposiMold. Many casts can be performed using the same mold and then the mold can be remelted to make new molds. Make more unique molds with 1 pound of ComposiMold than with 20 pounds of other mold making materials. Great for many applications including casting figurines, designing protoypes, duplicating sculptures, molding models, making craft parts, and other objects. Works great with plaster, concrete and urethane (ComposiCast and others), epoxy, and even chocolate (Food Contact version)!Melt
Melt the Reusable Rubber Mold Making Material, ComposiMold, by heating in the microwave. Microwave times will vary. Start with short heating times until you understand how the microwave will heat the ComposiMold.
| Container Size | Microwave times (estimates-times will vary) |
|---|---|
| 6 oz | 30-60 seconds |
| 16 oz | 3 to 5 minutes, stir every minute |
| 32 oz | 7 to 10 minutes, stir every minute |
You can also melt in a double boiler.
Mold
To make molds, simply pour the ComposiMold over your master part after putting on a mold release and let the ComposiMold solidify by cooling. Remove the master part from the ComposiMold and pour or press in your casting material.
Reuse
With the ComposiMold, many casts can be made with the same mold including plaster casts and plastic casts. When you finished making duplicate parts, reuse the ComposiMold to make more molds and cast parts. The unique aspect of ComposiMold is that it can be continuously remelted and reused to make new, unique molds.
Mold Making Tips
Use a mold release (release agent) on the original when making the mold and in the mold when making your casting. Be sure to reach any crevices, but do not overuse the mold release as it may cause bubbles.
When heating for the first time in the microwave, use short durations to ensure that you do not overheat the ComposiMold.
