乐动体育滚球投注 材料與模具壽命是息息相關的，因此選擇什麼樣的模具材料決定著什麼樣的模具。材料對模具壽命的影響是材料種類、化學成分、組織結構、硬度和冶金質量等的綜合反映。
The mold material of curbstone is closely related to the mold life, so what kind of mold material to choose determines what kind of mold. The effect of material on die life is a comprehensive reflection of material type, chemical composition, microstructure, hardness and metallurgical quality.

不同材質的模具壽命往往不同。使用ABS與聚丙烯的材料，工藝性能良好。乐动体育滚球投注 往往壽命相對會比較長，衝模工作零件加工製造過程一般較為複雜。
The service life of different materials is often different. The material of ABS and polypropylene has good process performance. The service life of curbstone mold is relatively long, and the processing and manufacturing process of working parts of stamping die are generally more complex.

因而必須具有對各種加工工藝的適應性，如可鍛性、可切削加工性、淬硬性、淬透性、淬火裂紋敏感性和磨削加工性等。
Therefore, it must be adaptable to various processing technologies, such as malleability, machinability, hardenability, hardenability, quenching crack sensitivity and grindability.

通常根據衝壓件的材料特性、生產批量、精度要求等，選擇性能優良的乐动体育滚球投注 材料，同時兼顧其工藝性和經濟性，這樣才能使乐动体育滚球投注 的壽命。
Generally, according to the material characteristics of stamping parts, production batch, precision requirements, etc., the excellent performance of curbstone mold material is selected, and its processability and economy are considered at the same time, so as to make the life of curbstone mold
