Polytek development corp. 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. This video segment will show you how to make a simple urethane mold using tap urethane rtv system. Smooth on manufactures industry leading two component materials such as silicone urethane rubber urethane plastic urethane foam epoxy resin epoxy coatings and adhesives.

This will keep it form sticking too much. Injecting liquid into the mold allows for a wide variety of design capabilities but it is only conducive to making smaller parts. Higher densities can be made by restricting the expansion in closed molds. The molds are for animal ear shapes it s a long story and they need to be squishy and light weight.

Is a leading manufacturer of specialty polymers including. The injection method involves shooting the material into a mold at a very high speed. The material shot into the mold is either in the form of liquid or in the form of hardened polyurethane droplets. That can be used for low density structural or flotation applications.
