路沿石模具材料与模具寿命是息息相关的，因此选择什么样的模具材料决定着什么样的模具。材料对模具寿命的影响是材料种类、化学成分、组织结构、硬度和冶金质量等的综合反映。
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.

不同材质的模具寿命往往不同。使用ABS与聚丙烯的材料，工艺性能良好。路沿石模具往往寿命相对会比较长，冲模工作零件加工制造过程一般较为复杂。
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.

因而必须具有对各种加工工艺的适应性，如可锻性、可切削加工性、淬硬性、淬透性、淬火裂纹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.

通常根据冲压件的材料特性、生产批量、精度要求等，选择性能优良的路沿石模具材料，同时兼顾其工艺性和经济性，这样才能使路沿石模具的寿命。
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
