Ukusaswa kwentsimbi engatyiwayo kuphoswa ikakhulu ngokuphoswa kwewax elahlekileyo kuba inokufikelela kumphezulu ochanekileyo kunye nobukhulu.
Investment casting okanyeukulahlwa kwewax elahlekileyoyindlela echanekileyo yokuphosa i-complex eyinkimbinkimbi kufuphi-netha-shape iinkcukacha usebenzisa ukuphindaphinda kweepateni ze-wax. Ukuphosa utyalo-mali okanye i-wax elahlekileyo yinkqubo yokwenza isinyithi esebenzisa ipateni ye-wax ejikelezwe yiqokobhe le-ceramic ukwenza i-ceramic mold. Xa iqokobhe loma, iwax iyanyibilika, kushiyeke ukungunda kuphela. Emva koko icandelo lokuphosa lenziwa ngokuthulula isinyithi esityhidiweyo kwi-mold ceramic.
Izinto ezisetyenziswa ngokubanzi kakhulu zensimbi engenasici zibandakanya (kodwa zingaphelelanga): I-Stainless Steel: AISI 304, AISI 304L, AISI 316, AISI 316L, 1.4404, 1.4301 kunye nezinye ibakala lensimbi engenasici.
Intsimbi engatyiwayo inomlinganiselo ophantsi wechromium oyi-10.5%, nto leyo eyenza ukuba ixhathise ngakumbi kwiindawo ezinolwelo ezidlekayo kunye ne-oxidation. Iyaxhathisa kwi-corrosion kwaye iyaxhathisa, ibonelela ngobuchule obubalaseleyo, kwaye yaziwa kakhulu ngenkangeleko yobuhle bayo. Utyalo-mali lwensimbi engenastainless "luyakwazi ukumelana nomhlwa" xa lusetyenziswa kwindawo elulwelo kunye nomphunga ongaphantsi kwe-1200°F (650°C) kunye "nokumelana nobushushu" xa lusetyenziswa ngaphezu kobu bushushu.
Isiseko se-alloy element zayo nayiphi na i-nickel-base okanye i-stainless steel investment casting yi-chromium, i-nickel, kunye ne-molybdenum (okanye "i-moly"). La malungu mathathu aya kumisela ubume bengqolowa bokugalela kunye neempawu zoomatshini kwaye ziya kuba sisixhobo kwisakhono sokusabisa ukulwa nobushushu, ukuguga, kunye nokudleka.
Yethuisiseko sokugalela ngewax esilahlekileyoinokuvelisa isikoutyalo mali stainless steel castingsehambelana ngqo neenkcukacha zoyilo lwakho. Kwiindawo ezisuka kumashumi eegram ukuya kumashumi eekhilogram okanye ngaphezulu, sibonelela ngokunyamezelana okuqinileyo kunye nenxalenye engaguqukiyo ukuya kwinxalenye yokuphindaphinda.
Ngokuqhelekileyo, insimbi engenasici kufuneka iphonswe yinkqubo yokuphosa echanekileyo yotyalo-mali kunye ne-silica sol njengebhondi. Iintsimbi ze-silica sol castings zinezinga eliphezulu kakhulu lokuchaneka komphezulu kunye nokusebenza.
Ngenxa yeempawu zayo ezikhethekileyo zomzimba, i-casts stainless steel castings ithandwa kuluhlu olubanzi lwezicelo, ngakumbi ezo zikwimeko enzima. Iimarike eziqhelekileyo zotyalo-mali lwensimbi engenasici ziquka ioli kunye negesi, amandla ombane, ukuthutha, iinkqubo ze-hydraulic, imboni yokutya, i-hardware kunye nezitshixo, ezolimo ... njl.
Inkqubo ifanelekile kwimveliso ephindaphindwayo yecandelo lemilo yomnatha ukusuka kwiindidi ezahlukeneyo zetsimbi kunye ne-alloys ephezulu yokusebenza. Nangona ngokuqhelekileyo isetyenziselwa ukudubula okuncinci, le nkqubo isetyenziselwe ukuvelisa iifreyimu ezipheleleyo zeengcango zenqwelomoya, kunye neentsimbi zokujula ukuya kuma-500 kgs kunye nokuphoswa kwe-aluminiyam ukuya kuma-50 kgs. Xa kuthelekiswa nezinye iinkqubo zokuphosa ezifana ne-die casting okanye isanti casting, ingaba yinkqubo ebiza kakhulu. Nangona kunjalo, amacandelo anokuthi aveliswe kusetyenziswa utyalo-mali angabandakanya iikhontolo ezintsonkothileyo, kwaye kwiimeko ezininzi amacandelo afakwe kufutshane nemilo yenethi, ngoko ke afuna ukuphinda kusetyenzwe kancinane okanye angabikho emva kokuba esakhiwe.
I-silica sol casting process yeyona nto iphambili yentsimbi yotyalo mali yotyalo-mali lwe-RMC. Besiphuhlisa itekhnoloji entsha yezinto ezincamathelayo ukuze sifezekise ukonga ngakumbi kunye nemathiriyeli encamathelayo esebenzayo ukwakha iqokobhe le-slurry. Yindlela eyothusayo into yokuba inkqubo ye-Silica sol casting ithathe indawo yenkqubo yeglasi yamanzi erhabaxa engaphantsi, ngakumbi yokuphosa intsimbi engatyiwayo kunye nentsimbi yealloyi. Ngaphandle kwemathiriyeli yokubumba ehlaziyiweyo, inkqubo ye-silica sol casting nayo iye yahlaziywa yazinza kakhulu kwaye yanda ubushushu obuncinci.
