    • A sintering compound containing a sinterable powder and a binder removable in a debinding step is injected into a metal mold set provided with a sintering compound injecting mold, in a sintering compound molding step (S104). An add-on forming compound which becomes removable or separable from the sintering compound injection molded body in the debinding step or the sintering step is injected into the metal mold set provided with an add-on mold in an add-on forming step (S102). The sintering compound injection molded body and the add-on are formed integrally with each other in the metal mold set. The integral formation of the add-on and the sintering compound injection molded body enables to prevent damage during release from the mold and make easy to handle the injection molded body.
    • 在烧结复合成型工序(S104)中,将含有可烧结粉末和在脱脂工序中除去的粘合剂的烧结体注入到设置有烧结体注射模具的金属模具组中。 在脱脂步骤或烧结步骤中将与烧结复合物注射成型体相脱离或分离的附加成型化合物在附加成型步骤(S102)中注入设置有附加模具的金属模具组中, 。 烧结复合注射成型体和附加体在金属模具组中彼此一体地形成。 添加剂和烧结复合物注射成型体的整体形成能够防止从模具脱模时的损伤,并且易于处理注射成型体。
