Ukuphosa utyalo-mali (ilahleko yokuphosa) yindlela echanekileyo yokuphosa enokwenza imveliso entsonkothileyo kufutshane ne-net-shape iinkcukacha kusetyenziswa ukuphindwaphindwa kweepateni zewax. 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.
Ngokwezibophelelo ezahlukeneyo zokwakha iqokobhe, utyalo-mali lunokwahlulwa lube yi-silica sol binder investment casting, igilasi yamanzi isibophelelo sotyalo-mali kunye nokuphosa utyalo-mali ngemixube yabo njengezinto zokubopha.
Iglasi yamanzi, ekwabizwa ngokuba yiSodium Silicate, luhlobo lwe-soluble alkali metal silicate, eneglasi ekwimo eqinileyo kwaye yenza isisombululo seglasi yamanzi xa inyibilika emanzini. Ngokomahluko weentsimbi zealkali eziqulethwe, zimbini iindidi zeglasi yamanzi e-potassium kunye neglasi yamanzi yesoda. Le yokugqibela inyibilika ngokulula emanzini, iqulethe ukungcola okuncinci, kwaye inomsebenzi ozinzile. Ngoko ke, iglasi yamanzi yokuphosa utyalo-mali yiglasi yamanzi ye-sodium, eyi-Na20 · mSiO2, Isisombululo se-colloidal esicacileyo okanye esiguquguqukayo esakhiwe emva kwe-hydrolysis. Izinto eziphambili zeekhemikhali zeglasi yamanzi yi-silicon oxide kunye ne-sodium oxide. Ukongeza, ikwaqulethe ukungcola okuncinci. Iglasi yamanzi ayiyonto enye, kodwa ixubene neekhompawundi ezininzi.
Kwinkqubo yokuphosa utyalo-mali, i-binder yeglasi yamanzi kunye ne-coating inomsebenzi ozinzile, ixabiso eliphantsi, umjikelo omfutshane wokwenza igobolondo kunye nesicelo esifanelekileyo. Inkqubo yokwenza igobolondo yeglasi yamanzi ifanelekile ukuveliswa kwee-castings zotyalo-mali ezifana ne-carbon steel, i-low-alloy steel, i-iron cast, ithusi kunye ne-aluminium alloys ezifuna umgangatho ongaphantsi komhlaba.
Custom ingxubevange steel ukugalela oomatshini spare parts byinkqubo yokuphosa utyalo-mali olulahlekileyongeglasi yamanzi (isisombululo esinamanzi se-sodium silicate) njengezinto ezidibanisayo zokwenza iqokobhe. Umgangatho wokwenziwa kweqokobhe kuphembelela ukuchaneka komdlalo wokugqibela kwaye ke yinkqubo ebaluleke kakhulu ngexesha lotyalo-mali. Umgangatho weqokobhe unxulumene ngokuthe ngqo noburhabaxa kunye nokunyamezelana komgangatho wokuphosa kokugqibela. Ke ngoko, ngumsebenzi obalulekileyo kwisiseko sotyalo-mali ukukhetha indlela efanelekileyo yokuvelisa iqokobhe lokungunda.Ngokwezinto zokuncamathelisa ezahlukeneyo okanye izinto zokubopha ukwenza iqokobhe lokungunda, iimolds zotyalo-mali zinokwahlulwa zibe ngamaqokobhe ancamathelayo eglasi yamanzi, i-silica sol adhesive shells, ethyl silicate adhesive shells kunye ne-ethyl silicate-silica sol composite shells. Ezi ndlela zemodeli zezona ndlela ziqhelekileyo ezisetyenziswayo kwi-investment casting.
Iqokobhe lokungunda ngeglasi yamanzi (isisombululo esinamanzi sesodium silicate)
Ukwenziwa kotyalo-mali oluveliswe yiqokobhe leglasi yamanzi kunoburhabaxa obuphezulu bomphezulu, ukuchaneka komgangatho ophantsi, umjikelo omfutshane wokwenza iqokobhe kunye nexabiso eliphantsi. Le nkqubo isetyenziselwa ngokubanzi ukuphosa i-carbon steel, i-alloy iron ephantsi, i-aluminium alloy kunye ne-alloy yobhedu.
Iqokobhe lokungunda nguSilica Sol Shell (ukusasazwa kwamasuntswana e-silica esikali nano-scale emanzini okanye kwisinyibilikisi)
I-silica sol investment casting inoburhabaxa obuphantsi, ukuchaneka okuphezulu komgangatho, kunye nomjikelo omde wokwenza iqokobhe. Le nkqubo isetyenziswa ngokubanzi kwi-high-temperature-resistant heat-alloy castings, i-cast-resistant steel castings, i-casting steel stainless, i-carbon steel castings, i-alloy castings, i-aluminium alloy castings kunye ne-copper alloy castings.
Iqokobhe lokungunda nguEthyl Silicate Shell
Kwi-investment casting, ii-castings ezenziwe ngokusebenzisa i-ethyl silicate njenge-binder ukwenza iqokobhe libe noburhabaxa obusezantsi, ukuchaneka okuphezulu, kunye nomjikelo omde wokwenza iqokobhe. Le nkqubo isetyenziswa ngokubanzi kwi-alloy castings ekwazi ukumelana nokushisa, ukuchithwa kwensimbi enganyangekiyo ubushushu, ukuchithwa kwensimbi engenasici, i-carbon steel castings, i-alloy castings, i-aluminium alloy castings kunye ne-copper alloy castings.
Intsimbi yekhabhoni, intsimbi ephantsi ye-alloy, kunye neentsimbi zentsimbi zisetyenziswa kwizinto ezininziizicelo zoshishinokunye nokusingqongileyo. Ngamabakala amaninzi, isinyithi kunye ne-alloys yazo inokunyangwa ngobushushu ukuze kuphuculwe isivuno sayo kunye namandla okuqina; kwaye, ukulungelelanisa ubulukhuni okanye ukuqina kwiimfuno zesicelo sobunjineli okanye iimpawu ezinqwenelekayo zoomatshini.
I-alloy-resistant-resistant alloy steel castings zizinto zokugalela eziveliswe yinkqubo yotyalo-mali elahlekileyo eyenziwe ngentsimbi ye-alloy engagugiyo. Kwi-RMC Foundry, ezona nkqubo ziphambili zokugalela isanti esinokuzisebenzisa kwintsimbi enganyangekiyo kwingxubevange yentsimbi kukugalela kwesanti eluhlaza, ukugalelwa kwentlabathi egqunywe ngentlabathi, ukugalelwa kwesanti engabhakiyo, ukuphosa ugwebu olulahlekileyo, ukugalelwa kwevacuum kunye nokuphosa utyalo-mali. Unyango lobushushu, unyango lomphezulu kunye nomatshini we-CNC nazo ziyafumaneka kumzi-mveliso wethu ngokwemizobo yakho kunye neemfuno.
Phakathi kweendidi ezahlukeneyo zokuphosa i-alloys, intsimbi enganyangekiyo yokuphosa yintsimbi esetyenziswa ngokubanzi. Intsimbi enganyangekiyo yokuphosa iphucula ubukhulu becala ukuxhathisa ukunxitywa kweentsimbi zentsimbi ngokongeza umxholo ohlukeneyo wezinto ezixutyiweyo, ezinjengemanganese, ichromium, ikhabhoni, njl., kwialloyi. Ngexesha elifanayo, ukunyanzeliswa kokugqoka kweentsimbi zentsimbi ezigugileyo kuxhomekeke kwindlela yonyango yokushisa esetyenziswe yi-Foundry kunye nesakhiwo sokuphosa.
Ngokweempawu ezahlukeneyo zokunxiba, ukunxitywa kweentsimbi zentsimbi kunokohlulwa kube kukunxitywa kwe-abrasive, ukuncamathelisa okuncamathelayo, ukudinwa, ukunxitywa kwe-corrosion kunye nokunxiba okukhathazayo. Ukulahlwa kwentsimbi engagungqiyo kusetyenziswa ikakhulu kumashishini aneemeko ezintsonkothileyo zokusebenza kunye neemfuno eziphezulu zokusebenza koomatshini, njengokumbiwa kwemigodi, isinyithi, ulwakhiwo, amandla, i-petrochemical, ukongiwa kwamanzi, ezolimo kunye namashishini ezothutho. Ukulahlwa kwentsimbi ekwaziyo ukunxiba kusetyenziswa kakhulu kwiimeko zokuqhawuka kunye nomthwalo othile wempembelelo, njengezixhobo zokusila, ii-excavators, izityum, iitrektara, njl.
