1- Yintoni uShell Mold Casting?
I-Shell yokubumba i-Shell ibizwa ngokuba yi-pre-coated resin sand cast, i-shell shell yokubumba okanye i-core cast. Eyona nto iphambili ekubumbeni sisanti yentlaka e-pre-camera, ebiza kakhulu kunesanti eluhlaza kunye nesanti yentlaka. Ngapha koko, le santi ayinakusetyenziswa kwakhona. Ke ngoko, ukubunjwa kweqokobhe kuneendleko eziphezulu kunokuphosa isanti. Nangona kunjalo, xa kuthelekiswa nokuphosa isanti eluhlaza, ukubunjwa kweqokobhe kunezibonelelo ezininzi ezinjengokunyamezelana okuphezulu, umgangatho wobunjani obulungileyo kunye neziphene ezingaphantsi. Inkqubo ekubunjweni kweqokobhe ilungele ngokukodwa ukuvelisa ukubumba kweemilo ezinzima, iinqanawa zoxinzelelo, ubunzima bobunzima kunye nokuphosa okufuna ukugqitywa komphezulu ophezulu.
2- Athini amanyathelo eShell Mold Casting?
✔ Ukwenza iipateni zentsimbi. Isanti yentlaka eyenziwe kwangaphambili kufuneka ifudunyezwe kwiipateni, ke iipateni zesinyithi sisixhobo esifanelekileyo sokwenza iqokobhe lokubumba.
✔ Ukwenza Umngxunya weSanti owenziwe kwangaphambili. Emva kokufaka iipateni zesinyithi kumatshini wokubumba, isanti yentlaka esele igalelwe kwangaphambili iya kudutyulwa ipateni, kwaye emva kokufudumeza, ukutyabeka kwentlaka kuya kutyibilika, emva koko isikhunta sesanti sibe liqokobhe lesanti eliqinileyo kunye ne-cores.
✔ Ukunyibilikisa isinyithi. Usebenzisa iifanishi zokungenisa, izinto ziya kunyibilika zibe lulwelo, emva koko ukudityaniswa kweekhemikhali zentsimbi engamanzi kufuneka kuhlalutywe ukuthelekisa amanani afunekayo kunye neepesenti.
✔ Ukuthulula isinyithi. Xa isinyithi esinyibilikiweyo sihlangabezana neemfuno, ziya kugalelwa kubumbeko lweqokobhe. Ngokusekwe kubalinganiswa abahlukeneyo kuyilo lokuphosa, isikhunta seqokobhe siya kungcwatyelwa kwisanti eluhlaza okanye ngokungqinelana ngamanqanaba.
✔ Shot ukuqhumisa, Ukusila nokucoca. Emva kokupholisa kunye nokuqina kokuphoswa, i-risers, amasango okanye i-iron eyongezelelweyo kufuneka inqunyulwe kwaye isuswe. Ke ukulahlwa kwentsimbi kuya kucocwa sisixhobo sokukhupha isanti okanye oomatshini bokudubula. Emva kokuguba intloko yokugoba kunye nemigca yokwahlukana, iindawo ezigqityiweyo zokuphosa ziya kuza, zilinde ezinye iinkqubo xa kufuneka njalo.
3- Zeziphi iingenelo zeShell Mold Casting?
✔ I-Shell-mold castings ixhomekeke ngokuchanekileyo ngakumbi kunokuba i-cast cast.
Umphezulu ogudileyo we-castings ogqityiweyo unokufunyanwa ngokuphoswa kweqokobhe.
✔ ii-engile zoyilo ezisezantsi kunokusikwa kwesanti.
Ukungena kwegobolondo kuphezulu kwaye ke ngenxa yoko incinci okanye ayifumaneki.
✔ inkqubo Shell sokubumbela ifuna isixa esincinci kakhulu sentlabathi.
✔ Uomatshini bufumaneka lula ngenxa yenkqubo elula ebandakanyekayo ekubumbeni kweqokobhe.
4- Zeziphi izinyithi kunye neeAlloys ezinokuphoswa yiShell Mold Inkqubo yokuphosa?
• Isinyithi seCarbon yentsimbi: Intsimbi yeCarbon esezantsi, iCarbon yentsimbi ephakathi kunye neNsimbi ePhakamileyo yeCarbon ukusuka kwi-AISI 1020 ukuya kwi-AISI 1060.
• Yenza iiAlloys zentsimbi: 20CrMnTi, 20SiMn, 30SiMn, 30CrMo, 35CrMo, 35SiMn, 35CrMnSi, 40Mn, 40Cr, 42Cr, 42CrMo ... njl.
• I-Cast yentsimbi engenasici: I-AISI 304, i-AISI 304L, i-AISI 316, i-AISI 316L kunye nelinye ibakala lesinyithi.
• Yenza iiAlloys zeAluminiyam.
• I-Brass kunye neCopper.
• Ezinye izixhobo kunye neMigangatho xa kuceliwe
I-5- Yeyiphi indlela yokuNyamezelana enokuFunyanwa yiShell Mold Inkqubo yokuphosa?
Njengoko besikhankanyile ekubunjweni konyamezelo lokuphosa isanti, iqokobhe lomngundo castings linokuchaneka okuphezulu kakhulu kunye nokunyamezelana okungqongqo kunokuba isanti eyahlulayo. Apha koku kulandelayo yibakala lokunyamezelana ngokubanzi esinokuthi sifikelele kulo xa kusenziwa iqokobhe lethu lokuphosa kwaye lingabhaki i-furan resin sand cast:
✔ IBanga le-DCT nguShell Mold Casting okanye iFuran Resin Sand Casting: CTG8 ~ CTG12
✔ IBanga le-GCT nguShell Mold Casting okanye iFuran Resin Sand Casting: CTG4 ~ CTG7
