Abstract
Bodies for heating, for example electric sealing jaws, are produced according to the present invention by a method which includes compaction and densification or consolidation of pulverulent, metallic material in a mould. The mould (6) is first supplied with the pulverulent material (10) which is compacted, as well as treated with an impregnating solution (12). Thereafter, the body (2) is heated to dry the solution and to sinter the pulverulent material. The method gives a dense body possessing superior thermal conductivity.
Claims21
A method of producing a body for a heat sealing jaw by compaction and densification, or consolidation, of pulverulent, metallic material, the method comprising feeding the pulverulent material into a mould and compacting the pulverulent;
- and adding an impregnating solution capable of being converted into a metal oxide;
- and heating the body to a temperature requisite to both dry the impregnating solution and bond the oxide to the pulverulent, metallic material.
