Early vacuum furnace designs began as single-chamber technology in which the heating and cooling required in a typical cycle were performed in the same chamber. While this is a cost-effective furnace design, there are dueling and sometimes completely incompatible design features that are necessary for optimum heating and optimum cooling. Better and thicker insulation helps with heating efficiency, but it...Read More
