Ke kaʻina hana hoʻopaʻa ʻana o MIM

E hoʻomau mākou e hoʻolauna i kēlā me kēia kaʻina hana o ka ʻenehana Metal Injection Molding.

I kēia lā e kūkākūkā mākou e pili ana i ka sintering ʻo ia nā mea koʻikoʻi i ka wā MIM.

KA IKE KUMU O KA SINTERING

1) ʻO ka Sintering ka wela a hoʻolohe i ka pauka paʻa i kahi mahana haʻahaʻa ma mua o ka helu heheʻe o kāna mau mea nui, a laila hoʻomaha iā ia i kekahi ala a me ka wikiwiki, a laila e hoʻomaikaʻi ai i ka ikaika a me nā ʻano kino a me nā ʻano mechanical o ka compact a loaʻa. kekahi ʻano metala.

2) ʻO ke kaʻina hana maʻamau ʻo Powder compact–Furnace Charging–Sintering me ka Preheating, Heat Preservation and Cooling–Firing–Sintered products.

3) ʻO ka hana o ka sintering ka loaʻa ʻana o ka lubricant removal, metallurgical bonding, element diffusion, dimensional change, microstructure and ocidation prevention.

KA HOAKAKA POKOLI O KA HANA SINTERING

1) Haʻahaʻa wela Pre-sintering pae:

I kēia pae, ka hoʻihoʻi ʻana o ka metala, volatilization o ka adsorbed gas a me ka makū, decomposition a me ka wehe ʻana o ka mea hana i loko o ka compact.

2) Ke kaʻina hana sintering mehana wela waena:

Hoʻomaka ka recrystallization ma kēia pae.ʻO ka mea mua, hoʻihoʻi ʻia nā ʻāpana aniani deformed i loko o nā ʻāpana a hoʻonohonoho hou ʻia i loko o nā hua aniani hou.I ka manawa like, ua hoʻemi loa ʻia nā oxides ma luna o ka ʻili o nā ʻāpana, a ua hoʻokumu ʻia ka ʻāpana ʻāpana i kahi ʻāʻī sintering.

3) Mālama ʻia ka lohe ʻana i ka wela wela e hoʻopau i ke kahua sintering:

ʻO kēia kaʻina kaʻina hana nui o ka sintering, e like me ka diffusion a me ka holo holoʻokoʻa a kokoke i ka hoʻopau ʻana, e hana ana i ka nui o nā pores i pani ʻia, a hoʻomau i ka emi ʻana, no laila e hoʻemi ʻia ka nui mua a me ka nui o nā pores, a me ka density o ke kino sintered ua hoonui loa ia.

4) Ke kahua hoʻoluʻu:

ʻO ke kaʻina hana sintering maoli ka sintering, no laila, ʻo ke kaʻina hana mai ka mahana sintering a lohi i ka hoʻolili ʻana no kekahi manawa a laila hoʻomaloʻo wikiwiki a hiki i ka puka ʻana o ka umu ahi a hiki i ka lumi wela, ʻo ia hoʻi kahi pae e decompose ai ka austenite a hoʻokumu ʻia ka hale hope.

Nui nā mea e hoʻohuli ai i ke kaʻina hana sintering.A ʻo nā mea e pili ana i ka mahana, ka manawa, ka lewa, ka hoʻohui ʻana i nā mea, ke ʻano alloy, ka ʻiʻo lubricant a me ke kaʻina sintering e like me ka hoʻomehana ʻana a me ka wikiwiki.Hiki ke ʻike ʻia he mana koʻikoʻi kēlā me kēia loulou i ka maikaʻi o ka sintering.No nā huahana me nā hale like ʻole a me nā pauka like ʻole, pono e hoʻoponopono ʻia nā ʻāpana like ʻole.
