15-year precision mould making

    Because the function of various parts is different in the mold, so the requirement and the selection principle of the material are also different. Therefore, the selection of automobile punching die material is a very important work in the design of stamping die, it is not only related to the cost of the parts, but also seriously affect the production.
    Generally, the working part of the mold selection of materials is better than other parts. Different materials are usually used in accordance with the requirements of the mould. There are four main types:
    1, For the processing small size stamping parts and simple shape die working parts often use carbon tool steel, such as T8A, T10A, etc..
    2, For the processing large size stamping parts and complex shape die working parts often use alloy tool steel or high-speed tool steel, such as CrWMn, Cr12MoV, W18Cr4V, W6MoSCr4V2 etc..
    3, For stamping parts precision or die life requirements of relatively high mold work parts, commonly used hard alloy or steel bonded carbide YG15, YG20, GW50, etc..
    4, For large-scale mold work parts, commonly used ordinary cast iron or cast steel, and the cutting edge to be welded to strengthen, such as gray cast iron HT250, cast steel 2G270-500, etc..
    In the selection of auto stamping mold parts material, not only the working parts are very important, but also the guide pillar and guide sleeve parts are also very important, often used after carburizing and quenching of high quality low carbon steel or selection of bearing steel.
