MIM (metal injection molding)., He ʻano hou o ke kaʻina hana hana ʻāpana metala e hui pū ana i ke kaʻina hana hoʻoheheʻe ʻia a me kakaʻina metala pauda. Ua ʻike ʻia kēia kaʻina hana hou i ka hopena o 1970s a ua hoʻohana mua ʻia e hana i nā ʻāpana mea kaua māmā. I kēia manawa e hoʻolauna wau i kekahiMIM metala hoʻoheheʻe ʻia nā ʻāpanano na mea kaua.
ʻO JIEHUANG CHIYANG ʻO ka hui hoʻoheheʻe metala kiʻekiʻe:
Nā ʻāpana MIM mua: Nā ʻāpana MIM hoʻopili uila. Hoʻokumu ʻia kēia ʻāpana eʻenehana MIM (Metal Injection Molding).a hana ʻia e nā ʻāpana papa F15 (Ni-Co-Fe); ʻO ka hoʻomanawanui o ka lua he hoʻohui a i ʻole he 0.2mm. Hoʻohana ʻia kēia huahana hoʻoheheʻe metala no ka Opto-electronic packaging. ʻO kekahi o nā koi ʻo ia ka hoʻonui ʻana o ka mea pono e like me ke aniani i hoʻopaʻa ʻia.
ʻO ka manaʻo o ka mea kūʻai aku i ka hoʻāʻo ʻana i ka hana sila ʻana o ka pā uila MIM ma hope o ka waiho ʻana o nā ʻāpana i ka haʻalulu wela. Hoʻololi kēia ʻāpana i nā huahana i hana ʻia e ka ʻoki a me ka brazing. Hiki i nā ʻāpana MIM ke hoʻemi nui i nā kumukūʻai hana ma mua o nā ʻāpana i hana ʻia ma ke ʻoki ʻana.
Nā ʻāpana MIM SECOND: ʻO ka hoʻomanawanui ʻana o ka mīkini hoʻoheheʻe ʻia i nā ʻāpana ʻāpana kila o ka mea ʻike maka pō he 0.5%. ʻO ka mea injection i hoʻohana ʻia he thermoplastic binder a me ka hao-7% nickel alloy. ʻO ka nui o ke kino sintered hiki i ka 7.82 kenimika square. ʻO nā mea mechanical i kuhikuhi ʻia i nā kūlana ʻenehana: tensile ikaika 430MPa, yield strength 295MPa, hardness 55HRC (ma hope o ka carburizing a quenching), a me ka modulus o ka elasticity 203GPa.
ʻO kēia ʻāpana i hana ʻia e ka kaʻina hana hoʻoheheʻe mim metalaua hana mua ia ma ke oki ana. I ka nānā ʻana i ke ʻano paʻakikī o ka ʻāpana a me nā lua i loaʻa i nā ʻaoʻao like ʻole, ʻoi aku ke kumukūʻai. Hoʻohana ʻia ka mea ʻike pō no ka pū M-6. Ma muli o ka hoʻohana ʻana i ke kaʻina MIM, hiki ke hoʻemi ʻia ke kumukūʻai o nā ʻāpana e 60%. Koe wale no ka carburizing a me ke kinai ana, aole pono ka lapaau ana.
Nā ʻāpana mea kaua i hana ʻia e nā ʻāpana kaʻina hana MIM 2
