Solar Manufacturing designs and builds vacuum furnaces for vacuum heat treating, with a focus on energy-efficient hot zones and sophisticated automation and controls, plus the capability for high-pressure gas quenching. The company collaborates with its affiliate Solar Atmospheres, using a network of four U.S. facilities to test and refine furnace design, operation, repair, and maintenance. Its product lineup ranges from very large production furnaces, notably the HCB series, which can handle workloads up to 150,000 pounds and up to 48 feet in length, to mid-sized horizontal and vertical bottom-loading models. A more economical Mentor and Mentor Pro line offers compact footprints with graphite-insulated hot zones and SolarVac controls, and these units can be customized to meet specific requirements. Solar Manufacturing is based in Sellersville, Pennsylvania. In 2025, the company announced a partnership with Solar Atmospheres to support the development of a specialized carburizing process.
