The Science of Mold Making: What Makes ComposiMold Different

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 the exact same as the original part in size and shape. The same mold can be used to make many duplicates of the original model parts.

The term reusable mold is used as a way to describe the ability to remelt and reuse the same mold making material for many different and unique molds.

 Typical mold making materials such as latex, silicone, and polyurethane have several drawbacks for certain applications:
  • Current mold making materials can only make one mold. That mold can be used many times, but when you are finished making duplicates of your sculpture or artwork, the mold is no longer useful.
  • These one-use molds are difficult to fix if you make mistakes because the material does not stick to itself or leaves markings where the patching has occurred.
  • Current mold making materials are also expensive and priced out of reach for most potential mold makers, especially beginner mold makers.
ComposiMold works by melting the material to form a hot liquid. This liquid is used to make moulds for casting duplicate parts of an original component. When melted, this low viscosity polymeric material pours over, brushes on, pours in, or covers an original component. The mold making material cools as the heat leaves the material into the surrounding environment. Once the model part is removed, this flexible mold material is used to make duplicates of the original part. ComposiMold is compatible with: plasters, waxes, soaps, concrete, plastics, edible materials and many more. The number of castings you can create in each mold varies based on type of casting material and how complicated your mold is. Then...simply remelt the mold making material to reuse it for over 35 different model parts.
