Other factors

Mould steel selection, in addition to its use of performance and process performance, but also to consider its versatility and steel prices. Mould casting steel is generally not used in large quantities and for ease of preparation, the versatility of the steel should be considered and mass produced mould casting steel should be used as far as possible to facilitate procurement, preparation and material management. In addition, a comprehensive analysis should be carried out in terms of economy, taking into account the manufacturing cost of the mould, the production batch of the workpiece and the apportionment between the workpieces. A comprehensive techno-economic analysis of the mould material is carried out and finally a reasonable mould material is selected. Hardenability mainly depends on the chemical composition of the steel and the original tissue state before quenching; hardenability depends mainly on the carbon content of the steel. For hot work mould steel and plastic mould steel, the general mould size is large, especially for the manufacture of large moulds, its hardenability is more important. In addition, for the shape of complex easily generated heat treatment deformation of various molds, in order to reduce quenching deformation, often as far as possible using a quenching medium with weak cooling capacity.
