REDUCING THE CONTAMINATION TENDENCIES AND DEMOLDING FORCES IN ELASTOMER MOLDS BY MEANS OF SURFACE-TREATMENT

This article deals with the problems of demoldability and contaminatio n of injection and compression molds for elastomer processing. The the oretical background of adhesion of elastomers and contamination of mol d cavities will be explained, The practical part of the article examin es common hard solid layers in the processing of selected elastomers, The titanium nitride (TIN), titanium aluminium nitride (TiAlN), chromi um nitride (CrN) and chromium carbide (CrC) were used as hard solid la yers, The adhesion tendency of elastomers on mold cavity walls can be reduced to a large extend.
