The injection method involves shooting the material into a mold at a very high speed. Injecting liquid into the mold allows for a wide variety of design capabilities but it is only conducive to making smaller parts. Casting flexible polyurethane foam.

Foam it 3 4 5 8 10 10 slow 15 26 are expanding water blown liquid polyurethane foams in 3 4 5 8 10 15 and 26 pound densities. This will keep it form sticking too much. However if you have to use a foam made of another material be sure to coat it in liquid wax. Large array of epoxy resin products.

Higher densities can be made by restricting the expansion in closed molds. The material shot into the mold is either in the form of liquid or in the form of hardened polyurethane droplets. It is a compilation of past high profile concrete mold making projects and also features a never before seen project. Foam it expanding foams are easy to use and cure rigid and strong they can be used as a lightweight casting material backfill material for encapsulation or to make hollow castings.

Silicone molds are the best for casting foam replicas. I have been making a series of 3d printed molds recently see making a 3d printed mold and figured i should explain how i m doing the casting. Foam it series castable rigid urethane foam. Aeromarine products is a premier supplier of epoxy resin products urethane foam mold making supplies casting resins.

The molds are for animal ear shapes it s a long story and they need to be squishy and light weight. This product is a liquid two component polyurethane system that forms rigid foam with a nominal density of 2 12 lbs. Smooth on manufactures industry leading two component materials such as silicone urethane rubber urethane plastic urethane foam epoxy resin epoxy coatings and adhesives. Polyurethane elastomers and casting resins silicones epoxies and latex.

That can be used for low density structural or flotation applications. Foam it castable urethane foams will expand many times their original volume when mixed and poured.
