Uma uzibuza ukuthi iyiphi indlela eyonga kakhulu yokwenza noma iyiphi i-prototype?Khona-ke kufanele uzame i-vacuum cast.Ekufakweni kwe-vacuum, udinga ukuthi ube namazinga okushisa alungile lapho welapha izinto ezisetshenziswayo.
Ukuze uthole i-resin, udinga ama-degree Celsius angu-30 ukuze unciphise ukuncipha ngesikhathi sokucindezela kwe-vacuum imizuzu emi-5 kanye nezinga lokushisa lesikhunta elingu-60 degrees Celsius.
I-vacuum casting iyafana nokuphindaphinda usebenzisa isikhunta se-silicon.I-vacuum casting yepulasitiki kusetshenziswa isikhunta se-silicon yasungulwa ngeminyaka yawo-1960 emanyuvesi aseJalimane.
I-vacuum casting iyizuzisa kanjani inkampani yakho?Qhubeka ufunda lesi sihloko ukuze uthole.
1. Kuyini I-Vacuum Casting?
Lena inqubo yokuphonsa yama-elastomer esebenzisa ivacuum ukudonsa noma iyiphi into ewuketshezi esibunjeni.I-vacuum casting isetshenziswa lapho ukungena komoya kuyinkinga ngesikhunta.
Ukwengeza, inqubo ingasetshenziswa uma kunemininingwane eyinkimbinkimbi kanye nama-undercuts esibunjeni.Futhi, isetshenziswa uma izinto ezisetshenziselwa ukwenza isikhunta ziyi-fiber noma ucingo oluqinisiwe.
Le nqubo ngezinye izikhathi ibizwa ngokuthi i-thermoforming ngoba inqubo yokukhiqiza ihilela i-prototyping esheshayo lapho amashidi epulasitiki eshiswa ngaphambili.Izinto ezisetshenziswayo zishisisa kusengaphambili emshinini wokukhipha i-vacuum ozenzakalelayo kuze kube yilapho sezithambile futhi zithambile.
2. Isebenza Kanjani I-Vacuum Casting?
Ukukhipha i-vacuum kulandela inqubo esetshenziselwa ukwenza umkhiqizo wokugcina.
• Yiba Nemodeli Eyinhloko Yekhwalithi Ephakeme
Inqubo yokukhipha i-vacuum idinga ukuthi ube nemodeli eyinhloko yekhwalithi ephezulu.Imodeli yekhwalithi ephezulu ingaba ingxenye yezimboni ngokwayo.Ukwengeza, ungasebenzisa imodeli edalwe kusetshenziswa i-stereolithography, okuyisibonelo sezinhlelo zokusebenza ze-prototyping.
Kufanele ngaso sonke isikhathi uqinisekise ukuthi imodeli eyinhloko esetshenziswayo ilingana nobukhulu nokubukeka okufanele.Lokhu okokuqinisekisa ukuthi awekho amaphutha adluliselwa kumfuziselo wemodeli ngemva kokuqeda inqubo.
• Inqubo Yokwelapha
Imodeli eyinhloko ibe isihlanganiswa ibe isikhunta serabha ye-silicone enezingxenye ezimbili.Isikhunta selashwa ngaphansi kwamazinga okushisa aphezulu ukuze kuqinisekiswe ukuthi izingxenye ezimbili zinamathela ndawonye.Lokhu kusetshenziselwa ukuqinisa isikhunta futhi kusenze siqine.
Ngemva kokuba isikhunta seselashiwe, siyasikwa sivuleke ukuze kwembuleke isikhala esingenalutho phakathi nendawo, esinobukhulu obufana ncamashi bemodeli eyinhloko.Ngemuva kokuthi isikhunta sinqunywe kabili, sifakwa ekamelweni le-vacuum.Khona-ke, kamuva, isikhunta sigcwaliswa ngezinto eziqokiwe ukwenza umkhiqizo.
• Ukugcwalisa I-Resin
Kufanele ugcwalise isikhunta ngezinto ezikhethiwe.I-resin iphindaphinda izici zempahla yezimboni.I-resin material ivame ukuxutshwa ne-metallic powder nanoma iyiphi i-pigment enemibala ukuze kuzuzwe izici zobuhle noma ezithile zokusebenza.
Ngemuva kokuthi isikhunta sigcwaliswe nge-resin material, ifakwa ekamelweni le-vacuum.Ifakwa ku-vacuum ekamelweni ukuze kuqinisekiswe ukuthi awekho amabhamuza omoya esikhunjeni.Lokhu kwenzelwa ukuqinisekisa ukuthi umkhiqizo wokugcina awonakele noma wonakaliswa.
• Inqubo Yokugcina Yokwelapha
I-resin ifakwa kuhhavini ngesigaba sokugcina selashiwe.Isikhunta selashwa emazingeni okushisa aphezulu ukuze kuqinisekiswe ukuthi impahla iqinile futhi ihlala isikhathi eside.Isikhunta se-silicone siyasuswa esikhunjeni ukuze sisetshenziswe ekwenzeni ama-prototypes amaningi.
Ngemuva kokuthi i-prototype isusiwe esikhunjeni, iyapendwa futhi ihlotshiswe.Imidwebo nemiklamo isetshenziselwa ukuqinisekisa ukuthi umkhiqizo unokubukeka kokugcina okuhle.
3. Izinzuzo Ze-Vacuum Casting
Okulandelayo izinzuzo zokusebenzisa i-vacuum cast emikhiqizweni ephindaphindayo.
• Ukunemba Okuphezulu Nemininingwane Emihle Yomkhiqizo Oqediwe
Lapho usebenzisa i-silicone njengesikhunta emikhiqizweni yakho.Iqinisekisa ukuthi umkhiqizo wokugcina unokunaka okukhulu emininingwaneni.Umkhiqizo wokugcina ugcina ufana nowokuqala.
Konke ukunakwa kwemininingwane kuyacatshangelwa futhi kucatshangelwe.Ngisho noma umkhiqizo wangempela unejiyomethri eyinkimbinkimbi kakhulu, umkhiqizo wokugcina ubukeka njengowokuqala.
• Ikhwalithi Ephezulu Yomkhiqizo
Imikhiqizo eyenziwe kusetshenziswa indlela ye-vacuum casting ingeyekhwalithi ephezulu.Futhi, ukusetshenziswa kwe-resin kukuvumela ukuthi ukhethe into efanele ezosetshenziswa ekwenzeni umkhiqizo wokugcina.
Lokhu kukuvumela ukuthi ube nokukhetha okubanzi kokuvumelana nezimo, ubulukhuni kanye nokuqina okufunayo emikhiqizweni yakho.Futhi, lokhu kunethonya elikhulu ekubukeni kokugcina komkhiqizo kusukela impahla esetshenzisiwe idlala indima enkulu.
• Yehlisa Izindleko Zokukhiqiza
Ukusebenzisa inqubo yokukhipha i-vacuum ukwenza umkhiqizo ukonga kakhulu.Lokhu kungenxa yokuthi inqubo isebenzisa i-silicon ukwenza isikhunta.I-Silicone iyathengeka uma iqhathaniswa ne-aluminium noma insimbi futhi yenza imikhiqizo emihle yokugcina.
Ngaphezu kwalokho, impahla ikuvumela ukuthi wenze imikhiqizo eminingi kusuka esikhunjeni.Lokhu kwenza le nqubo ingabizi kakhulu uma iqhathaniswa nokusetshenziswa kokuphrinta kwe-3D.
• Indlela Enhle Lapho Ufuna Ukuhlangabezana Nomnqamulajuqu
Le ndlela iyashesha, futhi kukuthatha isikhathi esincane ukuqeda ukwenza imikhiqizo yokuqeda.Ungathatha izinsuku eziyisikhombisa kuya kweziyishumi ukwenza izingxenye ze-prototype ezisebenzayo ezingaba ngu-50.
Le ndlela iyamangalisa uma wenza imikhiqizo eminingi.Ukwengeza, kuhle uma usebenzela ukuhlangabezana nomnqamulajuqu.
4. Ukusetshenziswa Kwe-Vacuum Casting
I-vacuum casting isetshenziswa embonini yokudla neziphuzo ukwenza amabhodlela namathini.Ibuye isetshenziswe emikhiqizweni yokuhweba kanye nemikhiqizo yasendlini.
• Ukudla Neziphuzo
Imboni yokudla neziphuzo isebenzisa lo mkhiqizo ukupakisha imikhiqizo yawo yokugcina.I-vacuum casting ingasetshenziswa ekwenzeni amabhodlela epulasitiki namathini.
Njengoba le nqubo ingasetshenziswa ukwenza imikhiqizo ngokushesha futhi ngezinga elikhulu, ithandwa kakhulu kulezi zimboni.
• Imikhiqizo Yezohwebo
Le nqubo isetshenziselwa ukwenza imikhiqizo yokuthengisa engasetshenziswa ekupakisheni.Iningi lemikhiqizo eyenziwa kusetshenziswa le nqubo ihlanganisa izibuko zelanga, amakesi eselula, amaphakheji okudla neziphuzo, namapeni.Le ndlela idala amathuba omsebenzi kubantu abafuna ukungena ekudayiseni eminye yale mikhiqizo.
• Imikhiqizo Yasekhaya
Eminye imikhiqizo yasendlini yenziwa kusetshenziswa inqubo yokukhipha i-vacuum.Imikhiqizo yansuku zonke efana nezihlanzi zokuwasha, ukucubungula ukudla, nezimonyo zenziwa kusetshenziswa le nqubo.
Uma uthola imikhiqizo yakho ezinkampanini ezisezingeni eliphezulu, maningi amathuba okuthi zisebenzise inqubo yokukhipha ivacuum ukwenza imikhiqizo.
Umugqa Ophansi Ku-Vacuum Casting
I-vacuum casting iyonga kakhulu uma kuqhathaniswa nokuphrinta kwe-3D noma umjovo wokubumba.Lokhu kukuvumela ukuthi ukhiqize imikhiqizo eminingi ngezindleko eziphansi.
