Title:
METHOD FOR SINTERING WORKPIECES TO BE SINTERED, AND SYSTEM FOR THIS PURPOSE
Document Type and Number:
WIPO Patent Application WO/2015/000584
Kind Code:
A3
Abstract:
In a method for sintering workpieces to be sintered, the workpieces (22) to be sintered are debindered in an oxygen-free or at least oxygen-reduced inert gas atmosphere, wherein a debindering atmosphere is generated which is loaded with binding auxiliaries that are released from the workpieces (22) to be sintered during the debindering process. The workpieces (22) to be sintered are brought to a sintering temperature (T2), wherein a sintering discharge gas is generated, and the workpieces to be sintered are cooled in a controlled manner. The sintered workpieces (22) are debindered in a separate debindering chamber (28) and sintered in a separate sintering chamber (30). The invention further relates to a system for sintering workpieces (22) to be sintered.
