Abstract

A device including an injection molding tool for use once or a few times for producing a sinterable ceramic and/or metallic product. The device includes at least one first tool part. At least one second tool part is combinable with the at least one first tool part to form a molding space for the product. The second tool part is produced using a wet composition and is made of a readily worked and form-stable material containing pores and admixed heat-conducting particles. A wet composition-enclosing member can engage the first tool part during the production of the second tool part. A unit can be connected to the at least one second tool part and can be arranged with the at least one first tool part for absorbing internal lateral displacement forces arising during squeezing or injection of an injection molding composition. The injection molding tool is adapted to receive an injection molding composition containing a ceramic and/or metallic powder that is introduced into the molding tool with low or medium pressure for forming the product. The pores and the admixed heat-conducting particles conduct away heat generated during the molding and gas trapped in the molding space. The pores also provide a well-balanced porosity for effecting conduction of the gas and, together with a flexibility in the solidified injection molding composition, permit the product to be separated from the tool parts without braking.
