Since the moving components and cavity of the mold are always hardened and ground ， they should produce between 500 000 and 1 000 000 000 shots. 高效率地生产各类注射成型零件首先取决于注射模具。 diverse [ daiv?:s ] a. 不同的, 多种多样的 模具的使用寿命取决于对它们的维护保养和加工处理，例如对一些活动件及型腔的表面硬化和磨削加工，使得它们的生产批量可以达到500 000～1 000 000 000件。 Grind [ graind ] （ground，ground） v.磨削，磨光 For ease of construction and to lower manufacturing cost， injection molds are becoming standardized. Some firms offer ready -made bases of square or round design as standard or stripper plate molds for immediate use. Only the inserts then have to be fitted into the bases.
