ʻO ka paleʻana i ka paleʻana i ke kāʻeiʻana ma. Ke hoʻomau mau nei

1. Hōʻikeʻike

Ma kānaʻano, Ua hoʻokaʻawaleʻia nā mea kūʻai aku iʻelua mau'āpana ākea: ʻO ka paleʻana i ka paleʻana, kahi i lukuʻia ai nā molds e kiʻi hou i nā'āpana, and Ke hoʻomau mau nei, kahi e hoʻoponopono hou ai nā molds i nā'āpana he nui.

Ke hoʻohālikelike nei i kēia mau kaʻina hana i nā mea i hoʻomālamalama pololeiʻia i nā kālepa, Kālā, a alakaʻi i nā manawa-ʻike i nā meaʻenehana a me nā hui limahana e kū pono ai e koho i keʻano kūpono.

Ua nānā kēiaʻatikala i kēlā me kēiaʻenehana i ka hohonu, loiloi i nā metala hana, a hāʻawi i nā alakaʻi no ke kohoʻana ma waena o nā mea kūʻai aku a me ka hoʻomau mauʻana.

2. He aha ka mea kūʻai liloʻana?

ʻO ka paleʻana i ka paleʻana e hoʻopuni ana i kekahi kaʻina hana i hāʻawiʻia e ka mold e hoʻihoʻi hou i ka'āpana i hoʻopaʻaʻia.

Nā mea loaʻa e kūkulu i kēia mau pale mai ke one, Pōʻai Pūnaewele, wax, a iʻole nā ​​mea hana cerramic a puni kahi hiʻohiʻona hou; ʻO ka manawa a me nā mea momonaʻo Molten a me nā mea paʻa, Ua wāwahiʻia ka mold, ke hoʻolilo nei iā ia no ka mea i piliʻole ai i nā pou o hope.

Loaʻa

• Hoʻolālā kūʻokoʻa: Hiki i nā molds ke hopu i nā geomet paʻakikī nui loa-a me nā mea i loko o nā cavities kūloko a me nā mea e pono ai nā mea kūʻai aku.
• Uku haʻahaʻa haʻahaʻa haʻahaʻa: ʻO nā kumukūʻai o nā mea maʻalahi ma waena o $500 and $5,000, making this approach economically attractive for low-volume or prototype runs.
• Laulā ākea ākea: From low-melting zinc to high-temperature steels and superalloys (a i 1,500 ° C), expendable molds accommodate virtually any material.

Loaʻa nā hemahema

• ʻO nā manawa lōʻihi lōʻihi: Typical sand‐casting cycles require 30–60 minutes ma kēlā me kēia (including mold prep and shake-out), hoʻohālikelikeʻia me 1-5 mau minuke in permanent molds.
• Hoʻopauʻo Rougher: Green-sand castings often exhibit surface roughness of RA 6.3-12.5 μM, necessitating additional machining.
• Dimensional Variability: Laina tolear o ± 0.5–3 mm limit the use of expendable molds for high-precision components without post-casting operations.

ʻO nāʻano o ka paleʻana o ka paleʻana

Expendable mold casting encompasses several processes, each tailored to specific part complexities, Pono nā koina, and material choices.

Below are the principal methods:

Sand cread

• Green-Sand: Uses a clay-water-sand mixture that remains pliable and reusable for thousands of molds.
  Hāʻawi i nā'āpana i nā'āpana he nui a me nā kumukūʻai e like me ka $ 0.10- $ 0.50 no kēlā me kēia paona.
• Resin-boned: Hoʻokomo i nā resins synthetic ma mua o ka pālolo, ʻO ka hāʻawiʻana i nā mea i hoʻonuiʻia (RA 3.2-6.3 μM) a me nā meaʻala (± 0.5 mm) No nā holo maʻalahi (500-5,000 PC).
• Nā wili lei: He lahui, ʻO ka Thermoset-resin "mau" i nāʻano heʻekuʻe i keʻano.
  Hoʻokomoʻo Shell i ka RA 1.6-3.2 μm hoʻopau a me ± 0.2 mM i nā mea kanu, e hana ana iā lākou no ka liʻiliʻi, nā hale kūʻai.

Waiwai kūʻai (Nalowale-wax) Kauhi

Kaulana loa e like me ka wā e kū ana, Hāʻawi kēiaʻano i keʻano kiʻekiʻe loa: nā mea hana o ± -,5 mm a me ka papa e hoʻopau ai i lalo i ra 0.8 }m.

Loaʻa i nā lole lole lole a iʻole nā ​​patmer a iʻole nā ​​patommer, A laila e hoʻopau i keʻano ma mua o ka nininiʻana.

ʻOiai e holo ana ka mea hana i $ 5,000- $ 20,000, E uku ia no nā'āpana ma lalo 1 MM Wall Pankness a me nā haʻahaʻa haʻahaʻa i nā helu Medibit (100-2,000 PCS).

Nalowale-wāwae

Nā hiʻohiʻona FAM (Eps a iʻole pla) E hoʻololi i nā kuʻuna kuʻuna. I ka hoʻopiliʻana me ka metala molten, ʻO ka soam soam, e waiho ana i kahi lua.

Nalowale-foam excels i ka paʻakikī, nā'āpana hoʻokahi-'āpanaʻole me nā kihiʻihiʻole aʻike i nā manawa maʻamau o nā manawa he 15-30 mau minuke i kēlā me kēia'āpana.

Pākuʻi Morold Kahuila

ʻO nā mea hoʻokūkū kiʻekiʻe a iʻole nā ​​mypsum gypsum i hopu i nā kiko'ī maikaʻi (Ra 1.6 }m) a e hoʻohilahila i nā wela i ka 1 200 ° C.

Hoʻopili hou i kā lākou mau'āpana i nā 10-50, No laila lākou e pili ana i ka haʻahaʻa haʻahaʻa, ʻO nā mea kiko'ī kiʻekiʻe e like me Aerospace a me nā maʻi lapaʻau.

Cemic mold canding

Me ka hoʻohanaʻana i nā pale resramors holomua, ʻO kēia kaʻina hana i nā mea kanu superalia ma luna 1 400 ° C.

Hāʻawi ia i ka hiki i keʻano geometry geometry a paʻa i nā mea hana (± 0.1 mm) No nā paleʻo Nickel-e pili ana i nā'āpana o Turbine a me nā'āpana kiʻekiʻe kiʻekiʻe, albeit ma kahi kumukūʻai kiʻekiʻe a kiʻekiʻe loa (3-6 lā i kēlā me kēia batch).

3. He aha ka mea mālama mau loa?

Ke hoʻomau mau nei hoʻohana i nā mea hao hou-ʻoi aku ka mea kila a iʻole nā ​​mea hao ma ka hao-e noho mau ana ma waena o nā haneli he mau tausani.

Loaʻa i nā kiʻi i ka metala molten i kēia mau pale i paniʻia ma lalo o ka gravity, haʻahaʻa haʻahaʻa, a iʻole ke koʻikoʻi kiʻekiʻe.

Ma hope o nā meaʻala maʻalahi, e lele ka make a ejects i kahi'āpana kokoke-net-mode me ka lukuʻoleʻana i ka mū.

  ʻO ka hōʻai'ēʻana i nā waiwai e hoʻopili ana i kēia i ka ± 0.1 MM a me RA 0.8-3.2 μm, Akā ma ke kumukūʻai kiʻekiʻe.
• Mau loa E hoʻokō pinepine iā ± 0.1-0.5 mm tolerances a me ra 1.6-6.3 μm (a iʻole ral 0.8-1.6 μm no ke kiʻekiʻe kiʻekiʻe).
  ʻO kā lākou microstructure maikaʻi loa i hāʻawiʻia i 30 % ʻO nā poosity haʻahaʻa a me nā mea waiwai maikaʻi loa.

Manawa manawa & OLELO

• Nā Kūlana Kūʻai E noi i ka 30-60 mau minuke no ka mālamaʻana (Nā Mold) a iʻole 6-24 mau hola i kēlā me kēia batch (waiwai kūʻai).
  Ma ka hopena, waiho mauʻia ka hoʻokomo, nui no nā hiʻohiʻona nui a paʻakikī paha.
• Ke kāhea mauʻana holo i loko 20 S-5 min i kēlā me kēia'āpana, Ke hilinaʻi nei i ke kaomi a me ka alloy.
  Ka nininiʻana, email, a me ka hoʻokaʻawale houʻana i ka hana hou, Ke kūpono nei ia no ka medium- e holo ai ka nui-volume (≥ 2,000 nā PC).

Alloy & Hiki i ka hiki

• Nā WELDS FREE Hoʻounaʻia kahi kokoke i kahi alloy-mai Zinc i nā mea aloha-mahalo i ke kiʻekiʻe kiʻekiʻe, Nā Kūlana, a me nā pā.
  Ke hoʻomau nei lākou i ke koho no nā mea hoʻokele, Titanium, a me nā mea e pili ana i nā mea kūʻai aku ma luna 1,200 ° C.
• Mau loa E nānā i nā alloys non-ferrous: aluminum, Magnesum, zinc, a koho i nā bronzes bronzes.
  Nā kila a me nā meaʻala e merode, Ke hoʻopauʻana i nā mold mau loa e hoʻohana ai i nā alloys ma lalo o ~ 700 ° C (a me nā mea kūikawā kūikawā a hiki i ~ 1,050 ° C).

Kumukūʻai no kēlā me kēia'āpana & Wahī-

• ʻO ka hoʻoleiʻana nā mea hana haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa akāʻoi aku ka nui o ka hana a me nā kumukūʻai, wāwahi i ka 100-2,000 PCS. Mālamaʻo ia i ka waiwai no nā holo pōkole a me nā prototypes.
• Ke kāhea mauʻana pono i nā waiwai nui e make ai akā hāʻawi i nā hana hana haʻahaʻa a me nā helu scrap, wāwahi i ka 2,000-10,000 PCS.
  Ma waho o kēlā, Ua hāʻule loa nā kumukūʻai, pinepine 50-75 % ma lalo o nā mea likeʻole.

8. Hopena

ʻO ka liloʻana a me ka hoʻomau mauʻana i ka hanaʻana i kēlā me kēia e hāʻawi i nā pono kūʻokoʻa.

ʻO nā molū i lilo i mea e hoʻomālamalama ai i ka haʻahaʻa haʻahaʻa, paʻakikī, a me nā noi kiʻekiʻe-kiʻekiʻe, ʻOiaiʻo nā molū paʻa mau loa i ka medium- e holo nui ana i ke kiʻekiʻe e noi ana i ka pololei, ka māmā holo, a me ka hoihoi.

Ma ka kaupaonaʻana i nā mea e like me nā mea hana hana, manawa manawa, paulapua, a me ke koho koho,

Hiki i nā mea hana ke koho i keʻano o ka hanaʻana i keʻano, hoʻomaikaʻi maikaʻi, a me ka hoʻomaikaʻiʻana i ka manawa.

FaqS

He aha kaʻokoʻa nui ma waena o ka lōʻihi a me ka hoʻomau mauʻana?

ʻO ka paleʻana i ka paleʻana hoʻohana i nā mollds i hoʻopauʻia ma hope o kēlā me kēia kāhea (E.g., Sand, Pōʻai Pūnaewele, a iʻole cemic),

oiai Ke hoʻomau mau nei hoʻohana i nā mea hao hou e hoʻihoʻi hou i nā hale kūʻai lehulehu me nā'āpana kiʻekiʻe kiʻekiʻe.

ʻO keʻano kūʻai e kūʻai hou aku i ke kumukūʻai no ka hana haʻahaʻa haʻahaʻa no ka hana haʻahaʻa haʻahaʻa?

ʻO ka paleʻana i ka paleʻana ʻoi aku ka nui o kaʻoihana no ka haʻahaʻa haʻahaʻa a iʻole nā'āpana maʻamau no ka mea he haʻahaʻa haʻahaʻa haʻahaʻa aʻoi aku ka loli i nā loli.

ʻO keʻano e hāʻawi aku ai i kahi kūlana maikaʻi loa a me keʻanoʻo Dimensional?

Ke hoʻomau mau nei ʻO ka maʻamau maʻamau E hoʻopau i nā papa a me nā mea hoʻokele Ma muli o ka'ōlelo pololei o nā molds metala a me ka paʻaʻana i hoʻopaʻaʻia.

ʻOi aku ka maikaʻi o hoʻokahi ala no nā geometries intricate?

ʻAe. ʻO ka paleʻana i ka paleʻana, loa Kāhaka kūʻai kūʻai, nā mea maikaʻi loa ma ka hanaʻana i nāʻano paʻakikī a me nā paʻakikī paʻakikī e paʻakikī a paʻakikī paha e hoʻokō me nā mau mau hoʻomau mau.
