PLASTIC MOULD STEEL, The equivalent grade P20+Ni | DIN 2738 | AISI P20+Ni
DIN 2738 which is applicable for large & small plastic mold dies for Automotive Industries, Dies for Domestic goods , High finishing plastic Die, Boaster Plates of Presses, Die Holders & Shoe blocks for drop Hammers, Press Cassettes , Up setter Blocker, forging dies, Different dies & mold for plastic products etc. Although less expensive options such as Aluminum exist for making molds to be used for shaping plastic, steel is most often the optimum one. It may be impose more investment to begin with but this is offset by its undoubtedly greater operational life and better finish. Also the specialized steels that have been created for plastic molding make for rapid process speed – for any duration it can handle more repetitions than other materials and so enhance productivity. Steel properties as given below, however, have to be optimally matched to the specific application and these are: Degree of purity Polishability Uniformity of hardness and microstructure Wear resistance
