Compression Molded Life Jacket - Life Jacket made of compression molded EVA foam. Did not have access to 3D modeling software; so molds were cast from precision sculpted industrial modeling clay. To achieve proper buoyancy, Inner and outer clay panels of both the front and back of the vest, needed to be sculpted with extreme accuracy. The partially molded panels were used as decorative additions to an existing Coast Guard approved life jacket already being made by the company.

Compression Molded Life Jacket

Because the company did not have a 3D CAD system, the molds for the manufacture of the Compression Molded Life Jacket had to be sculpted by hand out of industrial modeling clay. These were then used to make the negative silicone molds.
