Reusable Mold Making Material, Making parts without the cost.

Here is a short demonstration of the use of ComposiMold. Low cost, easy to use, and reuse. ComposiMold is a reusable mold making material that works by melting and pouring. Many casts can be performed using the same mold. ComposiMold 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). ComposiMold 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. ComposiMold is flexible, rubbery, molding material that can be melted poured and reused. This material is a thermoplastic mold making material that is great for small mold parts using many different casting materials including plaster, cement, epoxy, polyurethane, and others. ComposiMold can be used for molds, mold making and as a resin. www.ComposiMold.com for more information on ComposiMold. www.ComposiTherm.com to order your own ComposiMold

Disadvantages of Latex * Strong ammonia smell. * Can only be brushed onto an original. * Many coats are necessary. * Can take up to two weeks to make mold. * Shrinkage. Casting with Latex * Good for casting concrete, wax or plaster. * Generally not used for casting urethane, polyester, or epoxy resins, or low-temp metal alloys. Advantages of Polysulfide * Soft, stretchy, and durable. * Last a very long time. * Moderate cost. * Will cure against water clay or clays containing sulfur. Disadvantages of Polysulfide * Accurate gram scale to weigh components. * Offensive odor. * May stain white plaster during casting. Casting with Polysulfide * Good for casting plaster or wax only. * Will not handle concrete, resins, or low-temp metal alloys. Advantages of Silicone Rubber * Best release properties of all the mold rubbers. * Model surface preparation minimal nor not necessary. * Release agent for casting often not necessary. * Most heat resistance to high temperatures. * Can cast low-tempmetal alloys such as tin and pewter. * High tear resistance. * Knotty tear propagation. * Very good chemical resistance. * Longest mold life ...

Mold making basics: Silicone Block Mold

Block mold explanation. This is the most basic mold method for silicone rubber. This is a good method when speed is more important than overall cost. We used 73-45 platinum silicone for this particular mold. A cut block mold like this works best with rubber that is shore A20 or higher. This means a medium rubber. Soft rubber such as Gel-10 would be too soft and would distort at the seams.

Mold Making Video - Silicone Plastique Basic Mold Making - Learn How to Use This Amazing Mold Putty

Here is a helpful mold making video created by www.MakeYourOwnMolds.com that teaches basic mold making techniques using an amazing mold putty called, Silicone Plastique. Mold making is a valuable skill that can be very useful for just about anyone who is involved in creating a physical object. I have taught thousands of people how to make molds and have come to realize that most people have a predetermined opinion that mold making is very technical and difficult to perform. It is true that mold making can be very complex, but you may be surprised to find that 90% of the physical objects around you right now can be molded with Silicone Plastique. The reason this is possible is because I have spent a decade and a half developing this amazing mold putty into a perfect consistency that feels like modeling clay and is very user friendly. Originally designed for chefs to be used in kitchens for food molds, Silicone Plastique is completely non-toxic, food grade and complies with FDA regulations concerning synthetic rubber coming into repeated contact with food. While chefs world wide use Silicone Plastique, it is amazing how this easy to use silicone mold making compound has found its way into many diverse areas. Scientist and engineers purchase Silicone Plastique in order to make molds of their inventions so they can have a collection of duplicate prototypes. Paleontologists use it to make molds of fossils right at the dig sight and in museum work shops. Restoration experts use ...

Mold Making and Casting: Casting R2 Rigid Foam

Here are 2 methods for achieving a good matte, paintable surface on rigid, urethane foam. Both baby-powder and primer (sprayed into the mold and allowed to dry) may be used to create a cast part with a matte surface for easy painting. New Prime-it primer may also be used to simplify the painting process.
