Ukwenziwa kotyalo-mali, okwakwaziwa njengenkqubo ye-wax elahlekileyo, yenye yeendlela zakudala zokubumba isinyithi, ezithatha iminyaka engama-5,000 edlulileyo. Iinkqubo yokuphosa utyalo-maliiqala ngokutofa iwax eyenziwe ngobunjineli kwindawo echanekileyo yokufa okanye ngeeprototypes eziprintiweyo ezikhawulezayo. Iipateni zewax eziveliswa nangayiphi na indlela zidityaniswa kwi-sprue kunye nekomityi yokugalela ngeceramic.
Ezi seto ze-wax ke zityalwe, okanye zirhangqwe, ngomxube we-silica slurry kunye nesanti ye-zircon ekhanyelayo. Iidyasi ezininzi zisetyenziswa de iqokobhe eliqinileyo ligqume iipateni zewax ezidityanisiweyo. Eli lelona nqanaba lide kakhulu kwinkqubo yotyalo-mali njengoko iqokobhe kufuneka lome ngokupheleleyo phambi kokufaka iidyasi ezongezelelweyo. Ukufuma kunye nokujikeleza kudlala izinto ezinkulu ekuqhutyweni ngempumelelo kweli nqanaba.
Emva kokuba iqokobhe lome ngokufanelekileyo, iipateni zewax ngaphakathi zitshiswa ngaphandle kwegumbi loxinzelelo olushushu olubizwa ngokuba yi-autoclave. Emva kokuba yonke i-wax isusiwe, i-shell shell cavity ihlala; uphindo oluchanekileyo lwendawo efunekayo.
I-alloy efunwayo emva koko igalelwe kwi-cavity. Ezi alloys zinokubandakanya, kodwa azikhawulelwanga,ialloys-steel stainless, ubhedu, i-aluminiyam, okanye intsimbi yekhabhoni. Emva kokuba iimbumba zipholile, ziya kugqitywa apho iqokobhe le-ceramic lithatyathwa kwiindawo zentsimbi. Iiindawo zokuphosazisikiwe ke i-sprue, zithunyelwe ukuba ziqhume, zisile, kunye neminye imisebenzi yesibini yokucoca okanye ukugqiba ngokuxhomekeke kwiimfuno zamalungu.
Utyalo-mali lokuphosa izinto eziluncedo
Ngelixa kukho iindlela ezininzi zokwenza isinyithi, ukutyhilwa kotyalo-mali kwahlukile kuba kukuvumela ukuba ufumane iimilo ezintsonkothileyo kakhulu, ezifana noxinzelelo oluphezulu lokuphosa ukufa, kodwa kuzo zombini izixhobo ze-ferrous kunye ne-non-ferrous.
Izibonelelo zotyalo-mali xa kuthelekiswa nezinye iinkqubo zokwenza isinyithi:
- Ubunzima kunye nesakhiwo sengqolowa yezinto ezichasayo ezisetyenzisiweyo zivumela iimpawu eziphezulu eziphezulu.
- Ukugqitywa okungcono komphezulu ngokubanzi kuthetha imfuno encitshisiweyo yeenkqubo zoomatshini besibini.
- Iindleko zeyunithi nganye ziyancipha ngomthamo omkhulu, ukuba i-automation ingasetyenziselwa ukunciphisa umsebenzi.
- I-Hard Tooling inobomi obude kakhulu kunokoezinye iinkqubo zokuphosa, njengoko i-wax etofwayo ayiqhubi kakhulu.
- Inokuvelisa iimilo ezintsonkothileyo ezinokuba nzima kakhulu okanye zingenzeki ngezinye iindlela zokusasa.
- Inokufezekisa ukunyamezela okuphezulu kunye nee-undercuts ezingenziwanga lula kuxinzelelo oluphezulu lokufa.
I-RMC: Ukhetho lwakho lokuCasa uTyalo-mali
I-RMC yiisiseko sotyalo-malingeyakheizixhobo zomatshini ezichanekileyongokunjalo nezakhono zokufumana ngaphandle. Ukuvelisa okungafunekiyo kunye nabasebenzi bethu abaqeshiweyo bavumela i-Avalon Precision Metalsmiths ukuba ihlangabezane neemfuno zabathengi bethu kungekuphela kwendlela yokulahla iwax elahlekileyo, kodwa nangayiphi na enye indlela yokuphosa.
Ngezixhobo zobuNjineli kuzo zontathu iindawo zasekhaya, iqela loPhuhliso lweMveliso eNtsha (NPD), amandla okuthengisa ajikeleza unxweme ukuya elunxwemeni, kwaye ngaphezulu kweminyaka engama-20 kushishino, sinokukunceda ukonga ixesha kunye nemali ngokulawula inkqubo ekhawulezileyo kunye nesantya sokuthengisa. .
