    摘要： The present invention discloses a metal injection molding method, which is adapted to a mold having multiple mold cavities, and includes a feedstock preparation step, a molded articles ejection step, a classification and management step, a wax-based material removal step, a sintering step, and a compacting step. The classification and management step is to classify molded articles according to differences of the molded articles. The sintering step is to sinter the molded articles with sintering parameters. In this manner, tolerance caused by injection molding process is reduced because of the classification and management step and the sintering step, whereby further improving productive rate and quality of products produced from the mold with multiple mold cavities.

    摘要： A sintering chamber structure adapted to store multiple articles to be sintered in a sintering furnace, includes a first wall, a second wall, two side walls interconnecting the first and second walls, at least two supporting walls, and holding boards for holding the multiple articles. The two side walls and the first and second walls together define a storage space communicating outside. The two supporting walls correspondingly form a plurality of guiding grooves, wherein the first and second walls correspondingly form a pair of positioning slots communicating with the storage space, the at least two supporting walls are detachably inserted in the pairs of positioning slots, respectively, and the holding boards are inserted in corresponding guiding grooves. In this manner, the at least two supporting walls can adjust the inner space according to the sizes of the articles, whereby achieving the best yield of sintering.
