What is Mold Making?


Mold making is the process used to duplicate three dimensional models. Through the use of a mold making material (or mould making if you're in Europe) 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.

ComposiMold is a certified food contact safe, innovative product designed to enhance the mould making experience.  It is a reusable mold making material that can make over 35 unique molds and hundreds of castings with only one mold making material.  ComposiMold provides a unique solution to sculptors and artists by allowing users to easily fix errors by either using heat to reshape the mold or by re-melting the composite and starting the mold over. ComposiMold has been demonstrated to be melted and reused over fifty times.  Its formulation also provides a stable system with good mold strength, elongation of 150%, and longevity.   Currently, ComposiMold is the easiest, most flexible moulding system available: melt, pour, and use.  No dangerous chemicals are used in the product and therefore safe for both the end-user and the environment.

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 moulds.

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 mould 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.

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, the 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. This flexible mold material is used to make duplicates of the original part. What is Mold Making? The process used for duplicating an object.

This mold making material is used by melting and pouring around an original part or painting on to the surface of an original part. Many casts can be performed using the same mould. This reusable mold making material is good for the mold maker and craft artist because it can be reused to make different molds without worrying about wasting mold making material (such as urethanes, silicones, or Alginate). The material is an excellent material for those wanting to learn and become involved in sculpting, modeling, and mold making without having to worry about mistakes or wasting material. The material is flexible, rubbery, molding compound that can be melted poured and reused. This material is a thermoplastic mold making material with increased strength over the prior art  for molding parts using many different casting materials including plaster, cement, epoxy, polyurethane, and others.  The material can be used for molds, mold making and as a resin itself.

The reusable mold making material provides a unique solution to the 3-D sculptor and for small part prototype work. Any mistakes can be fixed using heat or by re-melting and remolding the original art piece without wasting material. Because of the reusability and ease of use, the initial cost for the artist is reduced allowing people to experiment with the artistic medium in ways they were not able to before. The uniqueness of the product makes it well suited for many mold making projects including crafts, ornaments, prototypes, and sculptures. It is compatible with most casting materials including, but not limited to: urethane, epoxy, polyester, polymer clay, clay, concrete, cement, chocolate, ice cream, ice, butter, polymer metal clay, and plaster. Casting systems may also include fillers such as, but not limited to: powders, fibers, metal pieces, paper, plastic, ceramic, glass, and different combinations.
