Plastic moulds for the production of plastic articles with structured surfaces are increasingly being etched by photochemical treatment. The achievement of a faultless design by photochemical etching depends on a great number of factors. The main objective of this research project was to investigate the influence of variables dependent on the steelmaking process, with reference to their interaction with the other factors, which influence the etching behaviour. The investigations covered all the tool steels and products of the steelmakers concerned, which are of importance for the processing of plastics, in some 120 different production variants. They are, therefore, representative of the conditions prevailing in practice.
