1. Hoʻoulu nā mea hana kālā: Pehea eʻoki ai i ke kauʻana a me ke kauʻana i ka hana
E mahalo maoli i nāʻokoʻa ma waena o nā moding moding vs sand, He mea pono ke nānā aku i ka nānāʻana o kēlā me kēia kaʻina hana, Hāʻawiʻia nā lima molt, a hoʻopau i nā'āpana i hoʻopauʻia.
ʻOiai e hilinaʻi nui ana ma ke one ma keʻano he mea kūʻai aku, kā lākou Nā Kūlana Kūʻai-ʻO, Nā Hale Hōʻikeʻike Uʻiʻiaʻo Resin-Puss i hoʻopaʻaʻia i nā wahi nui, ʻOiaʻiʻo, a me ke aniani.
He aha ka mea e wili ana?
Hanaʻia ma nā makahiki 1940, Shell Moding Casting he mea kūpono loa i kahiʻano o ke kauʻana o ka sanding.
Hoʻohana ia maikaʻi rein-cream sand e hoʻopili ana i loko o kahi'āpana, ʻO kaʻili ikaika i ka wā i hōʻikeʻia ai i kahi kumu hoʻohālike. Ua hui pūʻia nā'āpanaʻelua i hoʻopaʻaʻia e hoʻopili i ka mū.
Hāʻawi i kaʻili o kaʻili iʻoi aku ka maikaʻi o ka dimension, ʻOiai e maʻalahi e wāwahi i hope o ka hoʻoponoponoʻana.
Nā papa kiʻi:
- Hoʻomākaukau hoʻomākaukau: Kahi kumu hoʻohālike (maʻamau alumina, Kukui Kekuhi, a iʻole ka hao hao) ua pāʻia i ka 180-250 ° C.
ʻAʻole like me nā mea kūʻai aku o Sand, ʻO nā hiʻohiʻona moding molding e kū pinepine ai (e hana i hoʻokahi hapa o ka mū) A me ka hōʻike i ka hana kūpono e hōʻoia ai e hōʻoia i ka replication maikaʻi. - ʻO ke kauʻana o Sand: Uaʻokiʻia ka pākula wela, wāwahiʻia, a i kauʻia ma kahi moena o Resin-CASUS SARE (Ua hui pūʻiaʻo Silica ma ka 2-5% resin thermoset, E.g., pahū poluli, a he catalyst).
ʻO nā mea kūʻai aku e pili ana i ke kamaʻilio me ke kumu wela wela, ʻO ka hoʻopauʻana i nā mea liʻiliʻi e hana i kahi'āpanaʻili. - Hānō manaʻo: Ua hoʻololiʻia a iʻole ka shaket a iʻole ka luluʻana e wehe i ka nui o ka nui, Ke waiho nei i kahi mea pena kiʻi (3-10 mm mānoanoa) e hoʻopili ana i keʻano.
Ua ho'ōlaʻia ka pūpū no 30-120 kekona (ma o ka wela o keʻano) a hiki i ke cross crosslinks, ʻO ka hoʻopaʻaʻana i kaʻili. - KahunaHila: ʻElua mau hale kupapaʻu (hoʻokahi no ka "cepe luna" a hoʻokahi no ka haʻahaʻa "drag") e hoʻopili pūʻia. Nā lua kūloko (E.g., nā lua, Nā Pana) ua hanaʻia e hoʻohana ana i nā cores o mua.
- E ninini ana: Palapala Molly (E.g., Ui, kila kohu ʻole) ua nininiʻia i loko o ka lua o kaʻili ma o nā'īpuka.
Hoʻomaopopo ka'ōwili i ka hoʻololi wikiwiki wikiwiki, ka hoʻoponoponoʻana i ka hoʻoponopono (1-5 mau minuke no nā'āpana liʻiliʻi). - Shell lawe: Ma hope o ka hoʻoponoponoʻana, Ua wāwahiʻia ka pūnāwai resin brittle (Via a iʻole ka pīhoihoi) e kiʻi i ka mea kūʻai aku.
ʻAʻole pono e hoʻokaʻawaleʻia kahi Shakeout, E like me ka crumbles i loko o nā'āpana liʻiliʻi.
E wehewehe i ka hiʻohiʻona: Shell mold casting produces a māmā māmā, dimensionly paʻa paʻa Me nā kiko'ī ākea maikaʻi loa.
Hoʻemiʻia i ka nui o ke kahe nui e hōʻemi ai i ka hoʻopauʻana a kākoʻo i ka hana maʻamau.
He aha ka mea e lele ana?
ʻO keʻano maʻamau a me keʻano kuʻuna, Sand cread, hoʻohana i kahi hui o Silica Sand, Nā Border Clayers (E like me Bentonite), wai, a me nā hoʻohui.
Ua hoʻohālikelikeʻia ke one a puni kahi hiʻohiʻona hou e hana ai i kahi neʻe. Ma hope o ka nininiʻana o ka mea molten i nā mea a me nā mea paʻa, Ua wāwahiʻia ka mold e kiʻi i ka mea kūʻai aku.
Hiki ke hoʻohuiʻia nā cores no nā'āpana hollow. Ua hoʻopaʻa pinepineʻiaʻo Sand, ʻOiai e koi ana i ka hōʻikeʻike ikaika.
'Ōmaʻomaʻo lā (Pahu Hema)
- Hana ʻana i ka poʻo: Ua huiʻiaʻo Silica Sand me 3-5% Clay (kaulike), 2-4% wai, a me nā hoʻohui (E.g., ʻO ka lepo lepo e hōʻemi ai i ka hōʻiliʻiliʻana).
Ua paʻiʻia kēia "Green Sand" a puni kahi hoʻohālike (Wood, mea meta, a iʻole plastic) I loko o kahi flask (kahi kūlana rigid) e hana i ka cope a me ka drag. - Kāohiʻia: Ua haʻaleleʻia keʻano o keʻano mai ke one, e waiho ana i kahi lua. Nā kihiʻihi (1-3 °) koiʻia e pale i ka pōʻino o ke one i ka wā hemo.
- Hui ai: Nā Kūleʻa Kūʻai (i hanaʻia mai ka nohona resin-bonend no ka ikaika) hoʻokomoʻia i loko o ka lua e hana i nā hiʻohiʻona kūloko.
- E ninini ana: Palapala Molly (E.g., Iron Roil, ʻaihue kīwī) ua nininiʻia i loko o ka puʻu ma o kahi'ōnaehana a me nā'ōnaehana Rusner.
He nui nāʻano o nā'ōmaʻomaʻo'ōmaʻomaʻo, aeʻae ana i nā gases e pakele i ka wā e ninini ana. - Ka Haakauaoha: Ma hope o ka hoʻoponoponoʻana (10-60 mau minuke no nā'āpana liʻiliʻi, hola no nā'āpana nui), Ua weheʻia ka flask, a ua laweʻia ka pāʻana i ka ukiuki a iʻole eʻoki ana i ke one.
Resin sand canding (Ke Ka Lehua Waiwai)
ʻO kahi mea maʻalahi e like me kahi e hoʻololiʻia ai ka belder green (E.g., Kauka Sun).
Ua ho'ōlaʻia ka Sandin Sand me ka wela a me nā catalysts, e hana ana i kahi paʻakikī, ʻoi aku ka lōʻihi. Hoʻopau kēia i ka hoʻonuiʻana o Sand a hoʻomaikaʻi i ka hoʻopauʻana i kaʻaoʻao akā e hoʻonui i ke kumukūʻai.
E wehewehe i ka hiʻohiʻona: Hāʻawiʻo Bulk Sand Molds ʻO ka weheʻole i ka nui o ka'āpana-From mau brackets liʻiliʻi e hoʻouna ai i nā mea waiwai e kaupaona ana i nā haneli o nā manamana wāwae.
Akā naʻe,, the softer mold walls and thermal expansion make sand casting less precise than shell mold casting.

3. Nā mea kūʻai aku a me nā'āpana kūpono
Shell molding vs sand casting differ significantly in their compatibility with metals, alloys, a me nā geometries hapa.
Nā metala kūpono a me nā alloys
Both processes handle gray/ductile iron, carbon/low-alloy steel, kila kohu ʻole, aluminum, copper-base alloys, a me hou aku.
Shell’s dry, rigid molds resist erosion with steel/iron; green sand is popular for aluminum due to cost and thermal considerations.
| Mea meta / Alloy | Shell Moding Casting | Sand cread (ʻōmaʻomaʻo / Resin) | 'Āpana |
| Iron Roil (Astm A48) | Suitable for small-to-medium parts | Suitable for small to very large parts | Sand casting is preferred for large engine blocks or structural components; shell molding is better for precise, Nā Kaʻi Hou. |
| Ui (Astm A536) | Ideal for precision parts | Possible, less precise | Shell molding ensures uniform nodule formation and controlled cooling; sand casting works for heavier, thicker parts. |
| Kila kohu ʻole (E.g., Cf8m) | Excellent for corrosion-resistant, Nā'āpana i hōʻikeʻia | Hiki ke hoʻoleiʻia akā me ka paʻakikī kiʻekiʻe | Ua paleʻo Shell Moding i ka modin, ka mālamaʻana i ka hoʻohuihui alloy; Hiki i ka'ōmaʻomaʻo'ōmaʻomaʻo ke kumu. |
| ʻO ka hao hao (Astm A216) | Suitable for small-to-medium parts | Makemake nuiʻia no ka nui, nā'āpana paʻa | ʻO nā mū nui o nā mū nui i lawe pono i nā mea kila kila nui; Hāʻawiʻo Shell Moding Moding i ka hoʻokeleʻoi aku ka maikaʻi no ka liʻiliʻi, nā mea hoʻohālikelike. |

FaqS
Hiki iā ia keʻimi i ka choding casting e hana i nā'āpana nui (E.g., 50 kg)?
A: ʻAʻole palupalu nā molds (3-10 mm) a nele i ka ikaika e kākoʻo nui ai, Nā pālahalaha nui. Nā'āpana Uila 20 Kg Story Swit Shell Coopse i ka wā e ninini ana.
Is sand casting cheaper than shell mold casting for small parts?
A: ʻAe-no nā haʻahaʻa haʻahaʻa (<15,000 Nā'āpana). ʻO ka mālamaʻana i nā kumukūʻai haʻahaʻa haʻahaʻa haʻahaʻa ($500- $ 10,000) Ke hele nei i ke kumukūʻai kiʻekiʻe ma mua, ʻOiai keʻano o nā mea kūʻai akuʻo Shell Mode ($10,000+) wale nō i hanaʻia ma ka nui o ka nui.
ʻOi aku ka maikaʻi o ke kaʻina hana no nā mea kila kila?
A: Shell mold casting—its resin shell prevents sand-metal reactions (E.g., ka hoʻokaʻawaleʻana i ka chromium, ka mea e hōʻemi ai i ke kū'ēʻana) a e hōʻoia i ka microsructure microstructure.
ʻO ke kapa o ke one o ka surn i nāʻeha a me ka pasosity ma ke kila kila.
Hiki iā ia keʻimi i ka undering e hoʻohana ana i keʻano'ōmaʻomaʻo?
A: No-shell molding casting e koi ai i ka sandin resin-cream e hana i nā'āpana rigid. 'Ōmaʻomaʻo (Clay-wai) lacks i ka ikaika e hana i kaʻili, ʻO ke kākoʻo kākoʻo pilikino.
He aha keʻano maʻamau o nā hiʻohiʻona no kēlā me kēia kaʻina?
A: Nā hiʻohiʻona moding (mea meta) hope 100,000+ Nā Pāʻani Pūnaewele; ʻO nā hiʻohiʻona o nā'ōmaʻomaʻo (Wood) hope <1,000 Nā Pāʻani Pūnaewele; resin sand sand (ʻO ITTLE / Wood) ʻO 10,000-50,000 mau hana.
