I-alloy yensimbi elahlekileyo i-foam castings yimveliso yentsimbi ephoswe yinkqubo yokuphosa ugwebu elahlekileyo. I-Lost Foam Casting (LFC), ekwabizwa ngokuba yiFull Mold Casting, luhlobo lwenkqubo yokwenza isinyithi kunye nenkqubo yokuphosa isanti eyomileyo. I-EPC ngamanye amaxesha inokuba mfutshane kwi-Expendable Pattern Casting kuba iipateni zogwebu ezilahlekileyo zingasetyenziswa kube kanye kuphela. Emva kokuba iipateni zamagwebu zigqitywe ngoomatshini abakhethekileyo, emva koko iipateni zeplastiki ezinogwebu zigqunywe nge-refractory coating ukuze zenze iqokobhe elomeleleyo lokumelana nentsimbi etyhidiweyo. Iipateni ze-foam ezinamaqokobhe zifakwa kwibhokisi yesanti, kwaye uyigcwalise ngesanti eyomileyo ejikelezileyo. Ngexesha lokuthululelwa, isinyithi esinyibilikisiweyo esiphezulu sobushushu senza i-foam iphethini i-pyrolyzed kwaye "inyamalale" kwaye ithatha indawo yokuphuma yeepatheni, kwaye ekugqibeleni i-castings efunwayo egqityiweyo ifunyenwe.
Ukulahlwa kwegwebu elilahlekileyo vs Ukuphosa kweVacuum | ||
| Into | Ukuphosa amagwebu alahlekileyo | Vacuum Casting |
| Iicastings ezifanelekileyo | Iicastings ezincinci neziphakathi ezinemingxuma entsonkothileyo, efana nebhlokhi yenjini, isigqubuthelo senjini | Ukusaswa okuphakathi kunye nokukhulu okunemingxuma embalwa okanye engekhoyo, enje ngentsimbi yokubala izinto ezichasene nentsimbi, izindlu zentsimbi. |
| Iipateni kunye neePlates | Iipateni ze-foam ezenziwe ngokubumba | Itemplate enebhokisi yokufunxa |
| Ibhokisi yeSanti | Amacala asezantsi okanye amahlanu akhupha | Amacala amane akhuphe okanye ngombhobho wokukhupha |
| Ifilimu yePlastiki | Ikhava ephezulu ivalwe ngeefilimu zeplastiki | Onke amacala eziqingatha zombini zebhokisi yesanti atywinwe ngeefilimu zeplastiki |
| Izinto zokugquma | Ipeyinti esekwe ngamanzi enetyali engqindilili | Ipeyinti esekwe ngotywala kunye nokwaleka obhityileyo |
| ISanti yokuBumba | Isanti eyomileyo erhabaxa | Isanti eyomileyo entle |
| Ukubunjwa kweVibration | 3D Ukungcangcazela | Ukungcangcazela okuthe nkqo okanye okuthe tye |
| Ukugalela | Ukugalelwa kakubi | Ukugalelwa kakubi |
| Inkqubo yeSanti | Ukunciphisa uxinzelelo olubi, jika ibhokisi ukuwisa isanti, kwaye isanti iphinde isetyenziswe kwakhona | Ukunciphisa uxinzelelo olubi, emva koko isanti eyomileyo iwela esikrinini, kwaye isanti iyaphinda isetyenziswe |
