ʻO ka neʻeʻana i ka paleʻana i ka uncompasses e hoʻopuni ana i kahiʻohana o nāʻenehana i loko o kahi i hoʻopauʻia a wāwahiʻia ka mold.
ʻO kēiaʻano hana hana hoʻokahi e hiki ai i keʻano o ka hoʻopiliʻana i nā geomet paʻakikī a me nā'āpana nuiʻole me kaʻole o ka hana paʻaʻole.
ʻO ka mea kūʻai aku i ka mea kūʻai aku-ʻo ia ka mea e lilo ai i ka hana maʻamau-mold-molld-mold.
Ma kēiaʻatikala ua hōʻole mākou i nā loina, mea waiwai, Nā Makana, a me nā noi o nā mea kūʻai aku i ka molū e hoʻolei ana ma ka laulā a hoʻohālikelike iā lākou i ka kiko'ī (nalowale-wax) Kauhi.
2. He aha ka mea kūʻai liloʻana?
ʻO ka paleʻana i ka paleʻana refers to any metal casting process in which the mold is used only once and then destroyed to retrieve the finished part.
Ma ka hoʻohālikelikeʻana i nā hana mau loa, ʻO kēia mahele e hoʻopau i ka pale e hoʻokō ai i kahi kūlana hoʻolālā, Nā uku haʻahaʻa haʻahaʻa,
a hiki i ka hiki ke hoʻolei i nā'āpana nui a paʻakikī paha a koʻikoʻi paha me kaʻole o ka hoʻolimalimaʻana i ke kumukūʻai, ʻO nā mea alakaʻi lōʻihi.

Ka mua, kahi hiʻohiʻona-maʻamau i hanaʻia i ka lāʻau, mea meta, palaki, a iʻole he polymer 3d i paʻiʻia i ka helu o keʻano o keʻano o ka'āpana.
A hiki, Hoʻopiliʻia ka mea i loaʻa i kēia kumu hoʻohālike i loko o kahi kumu e like me ke one, Pōʻai Pūnaewele, a iʻole slurry clurcy.
Ma hope o ka laweʻiaʻana o keʻano (Ma ka hoʻoheheʻe, kuni iho la, a iʻole e kau ana), Ua hoʻopihapihaʻo Molten i ka lua, Hoʻoponopono i, a haʻalele ka mold.
No ka mea,ʻaʻole hiki i ka mold ke hoʻopaʻaʻia i ke kaʻina hana i hoʻopaʻaʻia, ʻO nā mōhai loaʻa e hōʻike ai i ka hoʻolahaʻana.

6. No ke aha e hikiʻole ai ke hōʻoleʻia nā molden?
Nā hana e hoʻopau i nā molds i ukuʻia e hoʻihoʻi i nā'āpana. Ma ke kīwīʻo Sand, Ua haʻalele lākou i ka one i ke one mai ka mea hao paʻa.
ʻOiai a hiki i 90 % hiki ke kiʻiʻia ke one, Ua nalowaleʻo ia i kānaʻano hana mua a me ka ikaika.
NOEHUI, Pono ka mea i loaʻa e hoʻomaikaʻi a hoʻoponopono paha i ke one ma mua o ka hōʻikeʻana i ka hana maoli.
Like me, ʻO nā'āpana cemamic a me nā plaster molds crack i ka wā o Shake-Out aʻaʻole hiki ke ola, Pēlā e pāpā ai i ka hoʻoponopono pololeiʻana.
7. Hopena
I ka hopena, expendable mold casting vs. Kāhaka kūʻai kūʻai ʻO nā mea likeʻole o nā mea nui i ka hanaʻana i nā hana hou.
ʻO nā mea kūʻai aku i ka molds-nui loa a me nā surnan a me nā hana a me nā'āpana, kumukūʻai kūpono-kūpono no ka nui, e emi iki i nā'āpana.
Like, ʻO ka hoʻopukapuka kūʻaiʻana i nā mea kūʻai aku i ka hopena kiʻekiʻe, Kahiki Pāʻani Waiwai, a me nā mea waiwai, albeit me nā kumukūʻai kiʻekiʻe kiʻekiʻe a me nā manawa kiʻekiʻe.
Lākahi, Pono nā meaʻenehana e kaupaona i nā mea e like me keʻano o ka paʻakikī, nui ka laulā, koi pono, a me nā kumukūʻai ola e koho i ke kaʻina hana maikaʻi loa.
E like me nā mea hana hoʻolālā, hoʻohui hoʻohui-hana, a hoʻomau mau nā mea mālama i ka neʻeʻana, Loaʻa ka loaʻaʻana o nā mea loaʻa e hoʻokūkū nui e hoʻokūkū i kaʻenehana castiva e noi i nā koi noi.
LangHe ʻO ke koho kūpono kūpono no kāu hana hana e pono ai inā makemakeʻoe i ka maikaʻi kiʻekiʻe ʻO nā lawelawe paleʻana o nā lawelawe.
FaqS
What is the key difference between expendable mold casting vs. Kāhaka kūʻai kūʻai?
ʻO ka liloʻana o ka mea kūʻai aku i hoʻohanaʻia e hoʻohana ana i nā manawa hoʻokahi, plaster a iʻole ceramic i wāwahiʻia e hoʻokuʻu i ka'āpana,
ʻOiai ke kūʻai aku nei (kahiʻano o ke kaʻina hana mold) E hoʻolako i nā hiʻohiʻona Wax Wax a me nā multimani mau loa no nā papa hana kiʻekiʻe no ke kiʻekiʻe kiʻekiʻe a me ka nui.
Hiki iaʻu ke hoʻoponopono hou i ke one a iʻole cemamic mai kahi haʻahaʻa haʻahaʻa?
ʻAʻole hiki iāʻoe ke hana hou i ka pale iā ia iho, Akāʻo ka loaʻaʻana o nā mea hōʻike i 90 % o ke one a i ole 70 % o nā Media Cerramic ma ka hoʻomaʻemaʻe, Ke hoʻiʻana a me ke kāwiliʻana me nā mea hou ma mua o ka kūkulu houʻana i kahi mold hou.
Aia nā palena palena?
- Nā WELDS FREE: Ka hoʻohālikelike ākea (hae hao, Kukui Kekuhi, aluminum, bronze).
- Hoʻolei kālā: Kākoʻo i nā mea kōkua kūikawā (Nickel mau, Titanium), ʻOiai e koi paha nā metala reactive metactive i nā waiwai waiwai a me nā lewa.
Pehea eʻokoʻa ai ka hopena o ke kaiāulu?
ʻO nā kaʻinaʻelua e hoʻonui i ka hoʻoponoponoʻana i nā leka: ʻO ke kāʻeiʻana i nā cīnoki ~ 85.0phol % o ke one, ʻOiai ke kūʻai aku nei i nā mea kūʻai aku 95 % of Wax a ~ 70 % o ka cemic.
Akā naʻe,, Hoʻohanaʻia kēlā me kēia pōkole i nā binders a me ka ikehu no ka loaʻaʻana, No laila, hiki i nā hoʻomaʻamaʻa hoʻomaʻamaʻa a me nā mea kūʻai aku e hiki ke hōʻemi hou i ka pauʻole.
