G-M Enterprises, a Nitrex company, received a multimillion-dollar order from a global manufacturer of metal injection molding (MIM) products for two horizontal vacuum furnaces. These 2-bar sintering furnaces have a work area measuring 36 inches wide x 30 inches high x 84 inches long (900 x 762 x 2,100 mm), a 4,400-pound weight capacity, a maximum operating temperature of 2600°F (1430°C) and uniformity of +/- 10°F (+/- 5.5°C). A multistage debinder trap system designed to thermally extract binder from the parts is integral to the vacuum system. Sintering and debinding occur in a single cycle using a unique system design that is optimized to handle the maximum designed load capacity. Consequently, there is never a need to operate below the rated load capacity to achieve the required part quality.
The high-temperature sintering process also ensures a high-quality finished part surface in terms of density, porosity, mechanical resistance and aesthetics. The first furnace will be delivered this year, and the second furnace is scheduled for commissioning in March 2021.
