How To Make One-Part Molds with ComposiMold and ImPRESSive Putty
Mold making is the process used to duplicate three dimensional models. Through the use of a mold making material, a negative of a model part is made. That negative can be used to cast a second part that is identical to the original part in size and shape. The same mold can be used to make duplicates of the original Master parts. Check out the two videos below that show how to make one-part molds using ComposiMold Reusable Molding Material and/or ImPRESSive Putty, which are re-usable molds. You can re-melt and re-use as many times as you want as long as you don’t overheat the mold making material (boil it too many times). There’s no better product for making molds without wasting molding materials and getting great results.
One-Part Molds with ComposiMold
One part mold making is used when your part has a flat surface on one side such as a relief sculpture. Anything that can stand up on it’s own can be molded using the one part molding process. The process becomes very simple, especially with ComposiMold because you don’t have any mixing or weighing. Select a mold box that your part will fit into with at least a 1/2 inch around the sides. Plastic cups, bowls, even aluminum foil works well for the mold box.
- If you part is lightweight (such as a plastic toy) hot glue or use a tape dot to hold your Master down in your mold box.
- Spray your part/Master with mold release.
- Spray liberally with Bubble Buster to reduce surface tension.
- Melt the ComposiMold as described in the included instructions. You don’t need to melt everything, just what you need.
- Let the ComposiMold cool to solidify. Place in the refrigerator or freezer to cool faster
- Pull the mold from your mold box and pull out your Master from the bottom of the ComposiMold
- Pour or press in your casting material
- ComposiMold is a remeltable rubber, so when finished with that mold you can remelt it to make a New mold.
The depth of the part does not have to be shallow. For example candle molds are typically long and narrow, but can still be molded using the simple process for one part molds.
The casting material is poured or pressed into the mold indentation. Mold sizes can range from a few millimeters to many feet in size.
Mold making is used to make duplicates of a wide variety of creations ranging from car parts to Christmas ornaments. Why you would want to make your own molds depends a lot on what you are making. The mold can then be filled with casting materials of your choice. For example, many cake decorators or chocolate makers use molds to create unique shapes from their chocolates or use molds to shape fondant into special shapes. Home soap and candle makers enjoy duplicating unique shapes and designs that cannot be found.
