Abstract 1. A METHOD OF PRODUCING A PRECISELY DIMENSIONED SINTERED PRODUCT BY PRESSING A REFRACTORY POWDER ALONG ONE DIRECTION, COMPRISING: (1) FORMING A REFRACTORY POWDER INTO A FIRST BODY OF NON-UNIFORM DIMENSION ALONG THE SAID ONE PRESSING DIRECTION AND SIMILAR TO THE DESIRED PRODUCT IN SHAPE BUT ELONGATED AT THE SAME FIXED RATIO FOR ALL SECTIONS OF SAID DESIRED PRODUCT PARALLEL TO SAID PRESSING DIRECTION, (2) COVERING SAID FIRST BODY WITH A LAYER OF A PARTING AGENT HAVING A HIGHER SINTERING TEMPERATURE THAN THAT OF SAID REFRACTORY POWDER, (3) FORMING ANOTHER PORTION OF THE SAID REFRACTORY POWDER INTO AT LEAST ONE SECOND BODY WHICH HAS THE SAME DENSITY AS THAT OF SAID FIRST BODY AND WHICH INTERFITS WITH SAID FIRST BODY TO FORM A COMPOSITE BODY HAVING A UNIFORM THICKNESS IN SAID PRESSING DIRECTION, (4) ASSEMBLING SAID FIRST AND SECOND BODIES IN SAID COMPOSITE BODY, (5) PLACING SAID COMPOSITE BODY WITHIN A DIE, (6) COMPRESSING SAID COMPOSITE BODY WITHIN SAID DIE BY APPLYING PRESSING FORCE ALONG SAID PRESSURE DIRECTION OF SAID FIRST BODY TO PRODUCE A REDUCTION OF THICKNESS AMOUNTING TO SAID FIXED RATIO FOR ALL SECTIONS OF SAID FIRST BODY PARALLEL TO SAID PRESSING DIRECTION WHILE SUBJECTING THE COMPOSITE BODY TO THE SINTERING TEMPERATURE OF SAID REFRACTORY POWDER, ('') REMOVING THE COMPOSITE BODY FROM SAID DIE, AND (8) REMOVING THE RESULTANT SINTERED SECOND BODY FROM THE RESULTANT SINTERED FIRST BODY OF REDUCED THICKNESS IN SAID PRESSING DIRECTION TO YEILD SAID PRECISELY DIMENSIONED SINTERED PRODUCT AS SAID RESULTANT SINTERED FIRST BODY.
A METHOD OF PRODUCING A PRECISELY DIMENSIONED SINTERED PRODUCT BY PRESSING A REFRACTORY POWDER ALONG ONE DIRECTION, COMPRISING: (1) FORMING A REFRACTORY POWDER INTO A FIRST BODY OF NON-UNIFORM DIMENSION ALONG THE SAID ONE PRESSING DIRECTION AND SIMILAR TO THE DESIRED PRODUCT IN SHAPE BUT ELONGATED AT THE SAME FIXED RATIO FOR ALL SECTIONS OF SAID DESIRED PRODUCT PARALLEL TO SAID PRESSING DIRECTION, (2) COVERING SAID FIRST BODY WITH A LAYER OF A PARTING AGENT HAVING A HIGHER SINTERING TEMPERATURE THAN THAT OF SAID REFRACTORY POWDER, (3) FORMING ANOTHER PORTION OF THE SAID REFRACTORY POWDER INTO AT LEAST ONE SECOND BODY WHICH HAS THE SAME DENSITY AS THAT OF SAID FIRST BODY AND WHICH INTERFITS WITH SAID FIRST BODY TO FORM A COMPOSITE BODY HAVING A UNIFORM THICKNESS IN SAID PRESSING DIRECTION, (4) ASSEMBLING SAID FIRST AND SECOND BODIES IN SAID COMPOSITE BODY, (5) PLACING SAID COMPOSITE BODY WITHIN A DIE, (6) COMPRESSING SAID COMPOSITE BODY WITHIN SAID DIE BY APPLYING PRESSING FORCE ALONG SAID PRESSURE DIRECTION OF SAID FIRST BODY TO PRODUCE A REDUCTION OF THICKNESS AMOUNTING TO SAID FIXED RATIO FOR ALL SECTIONS OF SAID FIRST BODY PARALLEL TO SAID PRESSING DIRECTION WHILE SUBJECTING THE COMPOSITE BODY TO THE SINTERING TEMPERATURE OF SAID REFRACTORY POWDER, ('') REMOVING THE COMPOSITE BODY FROM SAID DIE, AND (8) REMOVING THE RESULTANT SINTERED SECOND BODY FROM THE RESULTANT SINTERED FIRST BODY OF REDUCED THICKNESS IN SAID PRESSING DIRECTION TO YEILD SAID PRECISELY DIMENSIONED SINTERED PRODUCT AS SAID RESULTANT SINTERED FIRST BODY.
