The company was founded in 1946 by Seth Combs and James Murphy. The main product line at the time was refractory metal coils (molybdenum and tungsten) used in the lighting and the electronics industry. CM began manufacturing furnaces in order to produce the coils and over time the manufacture of high temperature laboratory and production furnaces became CMs primary product. CM Furnaces has made two key decisions in its history that define its products: we decided to keep all our design and manufacturing in the USA where we can ensure tight quality control; and we kept our focus on the technical performance and quality of our furnaces despite the onslaught of cheap, low quality imported lab furnaces, often repackaged and sold by US companies as their own. Our strategy has paid off and over our 70 years in business,the CM Furnace brand has established itself as the Cadillac manufacturer of lab furnaces for serious scientific research and batch and continuous furnaces for production work. All of our furnaces provide advanced features and a design mindset making them quality standouts among all lab furnaces manufactured today. When you choose our furnaces its because quality, accuracy, performance, low maintenance, reliability, and a low lifetime cost of ownership matter to you.
