Abstract
The apparatus includes a glass mold having opposed principle surfaces, the mold being generally transparent to infrared radiation, with one of the principle surfaces for receiving moldable materials. A stand supports the mold. Infrared heaters are positioned approximate to the opposite surface of the mold. An infrared radiation reflector is positioned behind the infrared heaters so as to reflect infrared radiation back toward the mold.
Claims7
An apparatus for making parts from moldable materials comprising:
- a glass mold having opposed principle surfaces, said mold being generally transparent to infrared radiation, one of said principle surfaces for receiving the moldable materials;
- a stand supporting said mold;
- infrared heating means positioned approximate to the other principle surface;
- vacuum bag means sealed to said one principle surface of said mold about the periphery, the moldable materials forming an evacuatable envelope about the molded materials;
- means to draw a vacuum from said envelope;
- and
- an infrared radiation reflector positioned behind said infrared heating means so as to reflect infrared radiation back toward said mold.
