The mold meets the economic requirements
The principle of economy must be considered in the selection of die material to reduce the manufacturing cost as much as possible. Therefore, on the premise of meeting the service performance, the lower price should be selected first. If the carbon steel can be used, the alloy steel will not be used, and if the domestic material can be used, the imported material will not be used. In addition, the production and supply of the market should also be considered when selecting materials, and the selected steel grades should be as few as possible and concentrated.
