I have a product to fabricate but need help identifying the type of plastic molding technology, and a company to make it. What I need is a Styrofoam molded structure that has about 1/2" thick Styrofoam wall thickness with a hard plastic shell on one side. This molded product will be about the size of a breadbox. The hard plastic shell would ideally have a decorative finish, maybe a granite looking finish with a slight texture. Ideally I would like the company to be in So. California, but due to the unfriendly business climate in this state I'm pretty sure I won't find one nearby, so actually anywhere in the US is acceptable, the closer the better. Can any of you help? I appreciate the guidance.
