1- Yintoni ukuphoswa kwesanti?
Eyahlulayo Sand yinkqubo tranditional kodwa mihla. Isebenzisa isanti eluhlaza (isanti efumileyo) okanye isanti eyomileyo ukwenza iinkqubo zokubumba. Ukuphosa isanti eluhlaza yinkqubo yokuphosa i-oldes esetyenziswe kwimbali. Xa usenza isikhunta, iipateni ezenziwe ngomthi okanye ngentsimbi kufuneka zenziwe ukuze kwenziwe umngxunya. Isinyithi esityhidiweyo emva koko sigalele emqolombeni ukuze senze castings emva kokupholisa kunye nokuqina. Sand eyahlulayo kubiza ngaphantsi kunezinye iinkqubo eyahlulayo zombini kuphuhliso ngumngundo kunye neyunithi eyahlulayo inxenye.
Ukuphosa isanti, kuhlala kuthetha ukuphoswa kwesanti eluhlaza (ukuba akukho nkcazo ikhethekileyo). Nangona kunjalo, kule mihla, ezinye iinkqubo zokuphosa zisebenzisa isanti ukwenza ukungunda. Banamagama abo, njengokuphoswa kweshell ngomngxunya, i-furan resin camera isanti eyahlulayo (akukho hlobo lokubhaka), ukulahleka kwegwebu kunye nokuphosa.
2 - Zenziwa njani i-Sand Castings?
Sineentlobo ezahlukeneyo zokulahla kukhetho lwakho. Inxalenye yenkqubo yokuzikhethela yeprojekthi yakho iya kuba kukhetho lwenkqubo yokuphosa eya kuthi isebenze ngokufanelekileyo kwiimfuno zakho. Olona hlobo luthandwayo kukuphosa isanti okubandakanya ukwenza umzobo wento egqityiweyo (okanye ipateni) ecinezelwe yisanti kunye nezongezo ze-binder ukumisa okokugqibela ukuphosa. Umzekelo uyasuswa emva kokuba ubumbile okanye umbono wenziwe, kwaye isinyithi saziswa ngenkqubo yembaleki yokugcwalisa isithuba. Isanti kunye nesinyithi zahluliwe kwaye ukulahlwa kucociwe kwaye kugqityiwe ukuthunyelwa kumthengi.
3 - Isetyenziselwa Ntoni Isanti?
Ukuphoswa kwesanti kusetyenziswa ngokubanzi kwimizi-mveliso eyahlukeneyo nakwizixhobo zoomatshini, ngakumbi ekubunjweni okukhulu kodwa ngobungakanani obuncinci bokufuna. Ngenxa yexabiso eliphantsi lophuhliso lwezixhobo kunye nephethini, unokutyala iindleko ezifanelekileyo kwisikhunta. Ngokubanzi, ukulahlwa kwesanti lukhetho lokuqala kwimishini enzima enje ngeelori zomsebenzi onzima, iimoto zothutho zikaloliwe, oomatshini bokwakha kunye neenkqubo zamanzi.
4 - Zeziphi iingenelo zokuphosa isanti?
✔ Ixabiso eliphantsi ngenxa yezinto zalo zokubumba ezingabizi kwaye zinokuphinda zisebenze kwakhona kunye nezixhobo zemveliso elula.
✔ Uluhlu olubanzi lweyunithi ukusuka kwi-0.10 kg ukuya kwi-500 kgs okanye nangaphezulu.
✔ Ubume obahlukeneyo ukusuka kuhlobo olulula ukuya kuhlobo oluntsonkothileyo.
✔ Ilungele iimfuno zemveliso yobungakanani obahlukeneyo.
5 - Yeyiphi i-Metal kunye neeAlloys Ngaba isanti yakho eyahlulayo isiseko sayo ikakhulu?
Ngokubanzi, uninzi lwesinyithi olungenantsimbi kunye nolungenazintsimbi lunokuphoswa yinkqubo yokuphosa isanti. Kwizinto eziyintsimbi, i-grey cast iron, i-ductile cast iron, i-carbon steel, i-alloy steel, isixhobo sesinyithi kunye ne-alloys zensimbi ezingenasici zixhaphake kakhulu. Kwizicelo ezingafakwanga ndawo, uninzi lweAluminiyam, iMagnesium, iCopper esekwe kunye nezinye izinto ezingafakwanga zinokuphoswa, ngelixa iAluminiyam kunye nealloy yayo zezona ziphambili ezilahliweyo ngesanti.
I-6 -Uluphi uhlobo lokuNyamezelana olunokuPhumelela ngokuSikwa kweSanti?
Ukunyamezelana ekubunjweni kwahlulwe kwaba ngukuphosa uMlinganiso oDibeneyo (i-DCT) kunye nokunyamezelwa kweGeometrical Casting (GCT). Isiseko sethu singathanda ukuthetha nawe ukuba unesicelo esikhethekileyo kunyamezelo olufunekayo. Apha koku kulandelayo kukunyamezelwa ngokubanzi kwebakala esinokufikelela kuko ngokuphosa isanti eluhlaza, ukubumbela iqokobhe kunye nokungabhaki i-furan resin sand cast:
✔ IBanga le-DCT ngoKwenziwa kweSanti eluhlaza: I-CTG10 ~ CTG13
✔ IBanga le-DCT nguShell Mold Casting okanye iFuran Resin Sand Casting: CTG8 ~ CTG12
✔ IBanga le-GCT ngoKwenziwa kweSanti eluhlaza: I-CTG6 ~ CTG8
✔ IBanga le-GCT nguShell Mold Casting okanye iFuran Resin Sand Casting: CTG4 ~ CTG7
7 - Zintoni iiMold Sand?
Ukubumba kwesanti kuthetha ukuba iinkqubo zokubumba ezenziwe ngesanti eluhlaza okanye isanti eyomileyo. Iinkqubo zokubumba isanti ikakhulu zigubungela ibhokisi yesanti, i-spures, i-ingates, i-risers, i-cores yesanti, isanti yokubumba, izibophelelo (ukuba zinako), izinto ezitsalayo kunye nawo onke amanye amacandelo okubumba.
