He lālā ia o ka metallurgy a me ka ʻepekema waiwai. Hoʻohana nui ke kaʻina hana i ka pauka metala ma ke ʻano he mea maka a hoʻohana i ke ʻano o ka "forming + sintering" e hana i nā mea a me nā huahana. He kaʻina hana ʻupena kokoke e hana i nā ʻāpana paʻakikī ma ke kumu kūʻai haʻahaʻa. E like me ka hoʻokaʻawale ʻana o nā mea, hiki ke hoʻokaʻawale ʻia ka pauka Injection i MIM (Metal Injection Molding) a me CIM (Ceramic Injection Molding).
ʻO ka meaʻai hoʻoheheʻe ʻia metala he ʻāpana hui o ka pauka metala maikaʻi me ka haʻahaʻa oxygen haʻahaʻa a me ka sphericity maikaʻi ma o ka hoʻohui ʻana i nā mea polymer e hana ai i ka pauka. Loaʻa iā ia ka fluidity kiʻekiʻe, kiʻekiʻe sintering density, kiʻekiʻe kiʻekiʻe ka ikaika piha, ka paʻakikī maikaʻi, ka hopena polishing e like me ke aniani a me nā waiwai ʻē aʻe. Hoʻohana nui ʻia ka meaʻai hoʻoheheʻe metala no nā huahana hoʻoheheʻe metala i nā ʻāpana kelepona paʻa, nā ʻāpana akamai hiki ke hoʻohana ʻia, nā ʻāpana kaʻa, nā mea lapaʻau, nā ʻāpana aerospace a me nā kula ʻē aʻe.
Hoʻohana nui ʻia nā ʻāpana i hoʻomākaukau ʻia e ke kaʻina MIM ma nā kahua o ka aerospace, ʻoihana kaʻa, pale aupuni, kamaʻilio uila, mālama olakino, mīkini a pēlā aku. Ua lilo ia i ʻenehana kiʻekiʻe a hou i ka pauka metallurgy a me ka ʻoihana ʻoihana me ka hoʻomohala wikiwiki i nā makahiki i hala. Manaʻo ka mākeke MIM honua e ulu mai $ 3.1 biliona i 2018 a i $ 4.5 biliona i 2023.
Ua hoʻomaka ka mākele MIM o Kina e ulu mālie mai ka makahiki 2000. I loko o hoʻokahi ʻumi makahiki, ua hōʻike ka mākeke MIM kūloko i kahi manawa ikaika o ka hoʻomohala ʻana. Wahi a nā helu helu o ka Powder Metallurgy Association o Kina Steel Association, ʻoi aku ka nui o ka MIM home ma mua o 1 biliona yuan i ka makahiki 2011, a ua hōʻea ka mākeke i ka 4.85 biliona yuan ma 2015, ʻo ia ka 35.23% o ka mākeke mākeke MIM honua. I ka makahiki 2019, ua hoʻonui ʻia ka mākeke MIM kūloko i ka 8.4 biliona yuan, kahi ulu makahiki o 20%. Ua ulu ka mākeke MIM Kina i mea nui o ka mākeke MIM honua.
