Sintering furnace PDS 120 MO/14

The PDS type furnaces are available with a usable volume of 25, 120 and 250 l. With the special design of the PDS type furnaces, it is possible to do both, debinding and sintering in one furnace. For debinding, a special gas guiding configuration and molybdenum retort are utilized to protect the heating elements from all gaseous by-products. The heating elements and radiation shields are also constructed of molybdenum. The system is surrounded by a double walled, water cooled vessel. To prevent condensation of the byproducts in the gas outlet system, the tubes leading to the afterburner are heated. Debinding is normally performed at a slight overpressure, and upon request, the furnace can be configured for debinding under partial pressure. For partial pressure operation, a special oil pump is integrated into the furnace to pump the gaseous by-products out of the furnace and into the afterburner. After the debinding step, it is possible to increase the temperature up to 1450 °C for the sintering process. During sintering, a vacuum, partial pressure, or slight overpressure can be applied. The system operation is automated, and therefore, can support the use of Hydrogen up to 100 % purity. A touch panel interface is used for parameter programming and process visualization. The PDS offers two operation modes. The first mode is manual operation, which consists of manually adjusting all system features. The second mode is automated and allows the user to program the operational parameters of the furnace. Upon initiating automatic operation, the system performs an evacuation step, a leakage test, and an overpressure test.
