Since the moving ponents 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 生產(chǎn)各類 注射成型 零件 首先 取決于 注射模具。pl230。nd?daiz ] v. 標(biāo)準(zhǔn)化 ,使合于標(biāo)準(zhǔn) insert [ in39。 Recovery rate [ri‘k?v?ri] 回收率 ,復(fù)原 Capacity [k?‘p230。??f?:] 因此 。siti]容量 ,容積 Procedures [pr?‘si:d??]程序 。 stisaiz］ v.（使）成為可塑 。klu:??n]結(jié)尾 ,結(jié)局 Unit One Mold Constructions 模具結(jié)構(gòu) Only when the second parting line opened， the part would be released.
