I-Aluminium Casting iyindlela yokukhiqiza ukubekezelela okuphezulu nezingxenye ezisezingeni eliphakeme ngokuthela i-aluminium ebonakalayo ibe yinkimbinkimbi eklanywe ngokunembe futhi enembile ebonwe, isikhunta, noma ifomu. Kuyinqubo ephumelelayo yokukhiqizwa kwezinkinga eziyinkimbinkimbi, eziyinkimbinkimbi, ezinemininingwane ehambelana kahle nemininingwane yokwakheka kwangempela.
Inqubo yokuphonsa ye-aluminium
I-1.Permant Mold Casting
Izindleko eziningi ze-aluminium unomphela isikhunta isikhunta futhi ukwakheka kwesikhunta, okuvame ukwenziwa ngensimbi empunga noma ngensimbi. Isikhunta sibunjwe ekwakhekeni kwejometri yengxenye eklanyelwe imininingwane nokwakheka kwengxenye ehlukaniswe ngama-halves amabili. Enqubweni yomjovo, ama-halves wesikhunta avalwe ngokuqinile kangangokuba akukho moya noma ukungcola okukhona. Isikhunta sifuthelwa ngaphambi kokuthululwa kwe-aluminium ebilisiwe, engahle ishiswe, ithululwe, noma ifakwe.
Lapho kuphothulwa inqubo, isikhunta sivunyelwe ukupholisa ukuvumela ingxenye ye-aluminium ukuba iqinise. Uma sekupholile, ingxenye yasuswa ngokushesha kusuka kubumbi ukuvikela ukwakheka kweziphambeko.
Akunandaba ukuthi ilula kangakanani inqubo ingahle ibonakale, iyindlela yezobunjiniyela ngokwesayensi nangobuchwepheshe yokukhiqiza izingxenye eziphakeme zevolumu.
2.SAND RISHE
Inqubo yokuphonsa isihlabathi ifaka ukupakisha isihlabathi ezungeze iphethini ephindeka enesimo, imininingwane, kanye nokucushwa komkhiqizo wokugcina. Kufakwe ephethini yizimpi ezivumela i-molten yensimbi ukuthi ithululwe ekubumbeni nasekuthayizeni okushisayo ukondla ukuphonswa ngesikhathi sokuqina ukuvikela i-thrinkage posulity.
Kufakwe ephethini yi-Strue evumela insimbi ebilisiwe ukuba ifakwe kubumbi. Ubukhulu bephethini bukhulu kancane kunomkhiqizo ukuze uphendule nge-shrinkage ngesikhathi senqubo yokupholisa. Isihlabathi sinesisindo namandla okugcina ukwakheka kwephethini futhi simelana nokuxhumana ngensimbi ebilisiwe.
I-4.Vacuum Die Casting I-Vacuum Die Casting isebenzisa izindlu zensimbi ye-airtight ene-sprue ukuvula ezansi nokuphuma kwe-vacuum phezulu. Inqubo iqala ngokufaka i-Strue ngaphansi kobuso be-aluminium ebilisiwe. I-vacuum idalwe ekwamukeleni ukwahlukanisa ingcindezi phakathi kwe-die cavity kanye ne-aluminium ebiwe.
Ukwehlukahlukana kwengcindezi kubangela ukuba i-aluminium ebindayo igeleze i-Strue ibe yi-die cavity, lapho kuqinisa i-aluminium ebonakalayo. Ukufa kuyasuswa kulokho okwemukelayo, kwavulwa, futhi ingxenye iyakhishwa.
Ukulawula i-vacuum kanye nokwehlukana kwengcindezi phakathi kwe-die cavity kanye ne-aluminum ebonakalayo kwenza ukuthi kulawule inani lokugqekeza elidingekayo ngemiklamo yengxenye nezidingo ze-cang. Ukulawulwa kwesilinganiso sokugcwaliswa kuthuthukisa amandla okuthola ukuhluzeka kwengxenye ephelile.
Ukuba ne-SPREE kungeniswe ngaphansi kobuso be-aluminium elibunjiwe kuqinisekisa ukuthi i-aluminium ebiwonakayo izoba yi-alloy ecwengekileyo ekhululekile e-oxides kanye ne-dross. Izingxenye zihlanzekile futhi zizwakala ngezinto ezingaphandle zakwamanye amazwe.
5.IsticShussing
Ukuphonsa kokutshalwa kwezimali, eyaziwa nangokuthi ukuphonsa kwe-wax elahlekile, kuqala nge-wax kufakwe ku-die ukudala iphethini yomkhiqizo ophelile. Amaphethini we-waxed anamathele e-Strue ukwakha ukucushwa kwesihlahla ama-IKE. Lesi sihlahla sicwiliswa esihlathini esiningi, esakha igobolondo eliqinile lobumba ezungeze ukwakheka kwe-wax.
Lapho ubumba selibekile futhi lukhuni, lufudunyezwa nge-autoclave ukuqedela ukuphelelwa yi-dewax. Ukufeza izinga lokushisa elifiselekayo legobolondo, kushaywa kusethwa kusethwa ukuthi kugcwaliswe nge-aluminium ebiwe, okuthululelwa e-Strue futhi kudluliselwe ochungechungeni lwabagijimi namasango ezikhunjini. Lapho izingxenye ziqina ngamandla, i-ceramic ingqongqoshe ukushiya isihlahla izingxenye ezixhumekile ukuze zinqunywe esihlahleni.
6.Lost foam casting
Inqubo elahlekile ye-Foam Casting ngolunye uhlobo lokutshala imali lapho kuthathelwa indawo i-polystyrene Foam. Iphethini ibunjiwe kusuka ku-polystyrene emhlanganweni weqoqo njengomgijimi kanye nama-spries wokutshala imali. Ubuhlalu basePolystyrene bafakwa ekubumbeni okufudumele kwe-aluminium ngokucindezela okuphansi ngeSteam okungeziwe ukuze bandise i-polystyrene ukugcwalisa ama-polystyrene ukugcwalisa ama-calystyne ukugcwalisa imithambo.
Iphethini ibekwa esihlabathini esomile egcwele kakhulu esevunguli elihlanganisiwe ukuze lisuse ama-voids noma amaphakethe omoya. Njengoba i-aluminimu ebiwe isululwe esihlangeni sesihlabathi, igwebu lishiswa, kwakhiwa inkohliso.
Izicelo ezijwayelekile zokuphonsa i-aluminium
Ngenxa yezakhiwo zayo ezinhle kakhulu zenyama nangamakhemikhali, izimboni eziningi ezinkulu zisebenzisa i-cast aluminium. Nazi izinhlelo ezimbalwa ezijwayelekile ezibonakalayo.
1. Imboni yezokwelapha
Abakhiqizi beNtini Yezokwelapha bancike kuma-aluminium casts ngamandla abo nokuzithoba ekwenzeni ama-prosthetics, amathreyi okuhlinza, njll. Ngaphandle kwalokhu, inqubo ilungele ukwenza bobunjwa abayinkimbinkimbi futhi abanembile lapho imboni eyaziwa ngayo. Futhi, i-aluminium iyinto efanelekile ngenxa yokumelana nayo kokugqwala njengoba imishini eminingi yezokwelapha iza ukuxhumana noketshezi lomzimba.
2. Imboni yezimoto
Abakhiqizi bezimoto ezincike kuma-aluminium casts ngezakhiwo zabo ezingasindi ngaphandle kokubandakanya amandla nokuqina. Ngenxa yalokho, ithuthukise ukusebenza kahle kwamafutha. Ngaphezu kwalokho, ukwenza izingxenye zezimoto ezinobukhulu obuyinkimbinkimbi nenqubo yokusakaza i-aluminium kulula. I-Aluminium Casts ilungele ukwenza izingxenye ezinjengamabhuleki namasondo okuqondisa.
3. Imboni yeCulinary
I-Cast Aluminium ilusizo embonini ye-Culinary ngenxa yokuqina kwayo, ukumelana nokugqwala, engasindi, nokushisa okuhle kakhulu. Ngaphandle kwalokhu, okuqukethwe kufanelekile ngokwenza i-cookware ngenxa yokuqedelwa kwayo okuhle kakhulu kokushisa, okungukuthi, kungashisa futhi kuphole ngokushesha.
4 Imboni Yezindiza
Izingxenye ze-Aluminium zilungele imboni yezindiza ngenxa yokungasindi namandla abo. Isisindo saso esikhanyayo sivumela indiza ukuthi isebenzise uphethiloli omncane ukuze uphathe isisindo esithe xaxa.
