ABSTRACT:
A thermoforming method of fabricating a seamless, three-dimensional fixture capable of holding a liquid from a single sheet of “solid surface” material is described. The sheet is cut to desired dimensions, then heated to a desired temperature to make it malleable. The malleable material is then placed over a female or male mold, and formed to the shape of the fixture, utilizing a vacuum. The heated material is then allowed to conform to the mold shape until the desired deformity is achieved. The manufactured fixture is then allowed to cool in its restrained position, until rigid.
