Dɛn ne akwan a wɔfa so tow gu?
Casting processes no nkyekyɛmu + wɔn su ho nkyerɛkyerɛmu, a wɔahyehyɛ no fi nea ɛtaa ba so kosi nea ɛnyɛ nea ɛtaa ba so, ma ntease ne nea wɔkyere gu wɔn tirim a ɛnyɛ den.
I. Nneɛma a wɔde tow gu mu no akuw atitiriw (ahorow 8 a wɔtaa de di dwuma) .
1. Anhwea a wɔtow (nea abu so na ɛyɛ mfitiasede) .
Wɔde anhwea a wɔde nwene ne ade a wɔde kyekyere nneɛma na ɛyɛ anhwea nkuku, na wohwie dade nsu no gu mu ma ɛyɛ nwini na ɛyɛ den. Esu
Nea wɔde di dwuma no trɛw yiye: dade a wɔatow, dade a wɔatow, aluminium a wɔde afra, ne kɔbere a wɔde afra nyinaa yɛ nea wɔde di dwuma.
Wobetumi de ayɛ afã horow a ɛsõ yiye na ɛyɛ den yiye, a nkuku a ne bo nyɛ den na ne bo nyɛ den wom.
Ɔfa no yɛ rough na dimensional accuracy yɛ average, ɛfata ma batches a ɛnyɛ akɛse anaasɛ ma afã horow rough.
Adeyɛ no yɛ nea ɛyɛ mmerɛw na ɛyɛ mmerɛw sɛ wɔbɛsesa sɛnea wɔayɛ no.
2. Dade nkuku a wɔtow (hard nkuku a wɔtow) .
Fa dade a wɔde ayɛ, dade, ne nea ɛkeka ho di dwuma sɛ nkuku a ɛtra hɔ daa na san fa di dwuma mpɛn pii. Esu
Nneɛma a wɔde gu mu no dwo ntɛmntɛm, ɛwɔ nhyehyɛe a ɛyɛ den na ahoɔden ye sen nea wɔde anhwea nkuku na ɛyɛ.
Nsusuwii no pɛpɛɛpɛyɛ yɛ kɛse na ɔfasu no su ye.
Nkuku no bo yɛ den na ɛnyɛ nea ɛfata ma emu ntokuru a ɛyɛ den. Wɔfata ma nneɛma nketenkete a wɔyɛ no kɛse-.
Wɔtaa de di dwuma wɔ aluminium piston, ntwahonan, ne nsu ho nneɛma mu.
3. Nhyɛso a Wɔde Tow (Die Casting) .
Wɔ nhyɛso kɛse ne ahoɔhare kɛse ase no, wɔhyɛ dade no ma ɛkɔ dade nkuku no mu na afei wɔtow gu bere a ayɛ nwini awie no. Esu
Ɛyɛ adwuma yiye, ɛfata ma nneɛma akɛse-a ɛyɛ afiri a wɔde yɛ adwuma
Nsusuwii a ɛkorɔn pɛpɛɛpɛ, ɔfasu a ɛyɛ torotoro, a etumi tow afã horow a ɛyɛ tratraa-fasu a ɛyɛ den
Ebia ɛwɔ mu ntini, wontumi mfa ɔhyew-yɛ mfa nhyɛ mu den
Wɔde di dwuma titiriw ma aluminium afrafrade, zinc afrafrade, ne magnesium afrafrade afã nketenkete
4. Nhyɛso a ɛba fam-nhyɛso a wɔde tow
Wɔde hyɛ mu brɛoo fi ase kosi soro, a nhyɛso a ɛba fam na ɛyɛ pintinn wom. Esu
Adeyɛ a wɔde hyɛ mu no yɛ mmerɛw, na ntini kakraa bi na ɛwɔ mu na nea wɔde gu mu no yɛ den.
Ɛyɛ mmerɛw sen die casting na ɛyɛ pɛpɛɛpɛ sen sand casting.
Ɛfata ma nneɛma a ɛwɔ ahwehwɛde a ɛkorɔn te sɛ hubs, cylinder blocks, ne structure components.
5. Nsusuwii Pɛpɛɛpɛ Casting (Lost Wax Casting) .
Di kan yɛ wax nkuku → fa nneɛma a ɛyɛ hyew kata so → fa wax no nwene → hyew akorade no → hwie dade no gu. Esu
Esiane sɛ ɛyɛ pɛpɛɛpɛ kɛse na ɛyɛ torotoro nti, wobetumi de adi dwuma ama afã horow a ɛyɛ den a ɛnyɛ pɛpɛɛpɛ.
Enni baabi a ɛpaapae na ɛkame ayɛ sɛ enhia sɛ wɔyɛ ho adwuma akyiri yi.
Ɛka a ɛkɔ soro ne adwumayɛ a ɛba fam, ɛfata ma nketewa-batch high-botae afã horow.
Nhwɛso ahorow a wɔtaa yɛ: wimhyɛn engine nhama, valve ahorow, ne precision castings a wɔde yɛ hardware.
6. Centrifugal Casting a Wɔde Tow Nneɛma
Wɔde centrifugal tumi na ɛyɛ dade a wɔabɔ no wɔ nkuku a ɛkyinkyini mu. Esu
Nneɛma a wɔahyehyɛ no yɛ den, enni abon anaasɛ slag, na ɛwɔ mfiridwuma mu su a eye kyɛn so.
Ɛfata ma afã horow a ɛte sɛ nsukorade, kurukuruwa, ne nkaa{0}} (paipu, bushings, wheel rims) .
Ɛho nhia sɛ wɔde anhwea bɛhyɛ mu, na ɔfasu a ɛwɔ mu no ye.
Wobetumi de adi dwuma ama nipadua akwaa a ɛkyinkyini nkutoo.
7. Lost Foam Casting (Nkuku a Wɔde Gu Ankasa) .
Wɔde foam plastic na ɛyɛ nkuku no. Bere a wɔde anhwea ahyɛ mu ma awie no, wohwie dade no gu tẽẽ. Foam no yɛ nwini na ɛyera. Esu
Ɛho nhia sɛ wɔde nkuku biara di dwuma, enhia sɛ wɔpaapae mu, a ahofadi a ɛkorɔn koraa wɔ adansi mu
Wɔma adeyɛ no yɛ mmerɛw, na nneɛma a wɔsɛe no no sua
Ɛfata ma nnaka a ɛyɛ den, nnua a wɔde ayɛ, ne nkuku a ɛnyɛ hwee
Sɛ wɔkyekyem pɛpɛɛpɛ a, asase ani yɛ papa, na nneɛma a atwa yɛn ho ahyia ho adamfofa yɛ nea ɛfata
8. Nneɛma a wɔtow gu a ɛkɔ so
Dade a wɔabɔ no kɔ so sen kɔ nkuku no mu na ɛkɔ so twetwe nhama atenten. Esu
Nneɛma a wɔyɛ no yiye no yɛ kɛse yiye, na nneɛma a wɔde di dwuma no nso yɛ kɛse.
Ɔdan no yɛ pɛ, ɛfata sɛ wɔyɛ slab, billet, ne rod billets.
Dade a wɔyɛ ne aluminium adwumayɛbea akɛse na wɔde di dwuma kɛse.
Entumi nyɛ nsusuwii ahorow a ɛyɛ den, afã horow a ɛnyɛ den nkutoo.
II. Ntotoho ne Nsɛm a Wɔaboaboa Ano
Wopɛ sɛ woyɛ nea ne bo nyɛ den, kɛse-kɛse, na ɛyɛ den → Anhwea a wɔtow
Wopɛ pɛpɛɛpɛyɛ a ɛkorɔn, ɔfasu pa, ne dodow kɛse → Die casting, dade nkuku
Wopɛ ultra-pɛpɛɛpɛ a ɛkorɔn, nsusuwii a ɛyɛ den → Pɛpɛɛpɛ ayera-wax casting
Hwehwɛ afã horow a ɛyɛ den te sɛ tubes ne cylinders → Centrifugal casting
Hwehwɛ ahofadi a ɛsen biara wɔ nhyehyɛe mu ne akwan kakraa bi → Lost-wax mold
Wopɛ nneɛma a ɛkorɔn-a ɛyɛ papa te sɛ ntwahonan ne cylinder blocks → Low-pressure casting
Wopɛ billets akɛse-scale → Kɔ so tow
