Network optimization information.

In mould production costs, material costs generally account for 10% to 20%, while machining, heat treatment, assembly and management costs account for more than 80%. Therefore, the process performance of mould materials is one of the most important factors affecting mould production costs and the ease of manufacture.

Easy to handle

-Hot workability refers to the thermoplasticity, processing temperature range, etc.; - Cold workability refers to the cutting, grinding, polishing, cold drawing and other processing properties.

Cold work mould steels are mostly over-eutectic and lysitic steels, whose hot and cold working properties are not ideal and should be strictly controlled by their hot and cold working process parameters to avoid defects and scrap. At the same time by improving the purity of steel, reduce harmful impurities, improve the steel organization, improve the steel hot and cold working performance, reduce the cost of mold manufacturing. In order to improve the cold working performance of mould steel, since the 1930s, people began to study in the mould steel to add S, Pb, Ca, Te and other easy cutting processing elements or graphitized elements, so as to develop a variety of easy cutting mould steel.
