        冲 pressure mold as need impact, 振动, scratch, high pressure and tensile, and other negative 荷, in relatively high temperature degree lower as (如 cold pressure), as conditions complex, easy abrasion loss, fatigue, fracture, deformation and other phenomenon. therefore, for mold as parts material requirements ratio parts high. due to type pressure mold as conditions different, therefore for mold as parts material requirements has 差异.

        1.冲裁模材 material requirements: for/regarding thin sheet/plate mold as parts use requirements tool has high wear resistance and hardness, for thick sheet/plate 冲裁 模 remove requirements tool has high wear resistance, resistant pressure 屈服点 outer, is anti mold fracture or 崩刃, also tool has high fracture resistant force, relatively high resistant strong/high degree and tough property.

        2. deep material requirements: requirements mold as parts material tool has good resistant viscous property (resistant combined property), high wear resistance and hardness, strong/high tough property and relatively good processing properties, but also hot 处理时 deformation need small.

        3. cold pressure material requirements: requirements mold as parts has high strong/high degree and hardness, high wear resistance, is impact 折断, also requirements has tough property. due to pressure generate relatively large rise temperature, therefore also tool has heat resistant fatigue property and hot hard property.
