1- Kuyini Ukulingiswa kwesihlabathi?
Ukulingiswa kweSand kuyinqubo yokuphonsa ngokweqile kepha futhi yanamuhla. Isebenzisa isihlabathi esiluhlaza (isihlabathi esimanzi) noma isihlabathi esomile ukwakha amasistimu wokubumba. Ukuphonswa kwesihlabathi esiluhlaza kuyinqubo yokulingisa i-oldes esetshenziswe emlandweni. Lapho wenza isikhunta, amaphethini enziwe ngokhuni noma ngensimbi kufanele akhiqizwe ukuze akhe umgodi ongenalutho. Insimbi encibilikile bese ithululela emgodini ukuze yenze ukusakaza ngemuva kokupholisa nokuqina. Sand ekubunjweni kubiza kancane kunezinye izinqubo ekubunjweni kokubili ukuthuthukiswa isikhunta futhi iyunithi thusi ingxenye.
Ukulingiswa kwesihlabathi, njalo kusho ukusakazwa kwesihlabathi esiluhlaza (uma kungekho ncazelo ekhethekile). Kodwa-ke, kulezi zinsuku, ezinye izinqubo zokusakaza nazo zisebenzisa isihlabathi ukwenza isikhunta. Banamagama abo, njengokuphonswa kwesikhunta segobolondo, ukusakazwa kwesihlabathi esigcotshwe nge-furan (alukho uhlobo lokubhaka), ukulahlwa kwegwebu nokulahlwa komshini.
2 - Senziwa kanjani iSand Castings?
Sine ezahlukene ekubunjweni izinhlobo ozikhethele. Ingxenye yenqubo yokuzikhethela yephrojekthi yakho kuzoba ukukhethwa kwenqubo yokusakaza ezosebenza kangcono ngezidingo zakho. Ifomu elidume kakhulu ukusakazwa kwesihlabathi okubandakanya ukwenza okufana nocezu oluqediwe (noma iphethini) olucindezelwe ngesihlabathi nezithasiselo ze-binder ukubumba ukusakaza kokugcina. Iphethini iyasuswa ngemuva kokubunjwa kwesikhunta noma umbono, futhi insimbi yethulwa ngohlelo lomgijimi ukugcwalisa umgodi. Isihlabathi nensimbi kwehlukanisiwe futhi ukujikijelwa kuyahlanzwa bese kuqedelwa ukuthunyelwa kumakhasimende.
3 - Kusetshenziselwani Ukusetshenziswa Kwesihlabathi?
Ama-sand castings asetshenziswa kabanzi ezimbonini ezahlukahlukene nemishini yokulungisa, ikakhulukazi ukusakazwa okukhulu kepha ngobuningi obufunayo. Ngenxa yezindleko eziphansi zokuthuthukiswa kwamathuluzi nephethini, ungatshala izindleko ezifanele kusikhunta. Ngokuvamile, ukusakazwa kwesihlabathi kuyindlela yokuqala yokukhetha imishini esindayo njengamaloli asindayo, izimoto ezithutha impahla, imishini yokwakha nezinhlelo ze-hydraulic.
4 - Ziyini Izinzuzo Zokusakaza Isihlabathi?
✔ Izindleko Eziphansi ngenxa yezinto zayo zokubumba ezishibhile nezivuselelwa kabusha nemishini elula yokukhiqiza.
✔ Ububanzi obubanzi besisindo samayunithi kusuka ku-0.10 kg kuya kuma-500 kgs noma ngisho nangaphezulu.
✔ Ukwakheka okuhlukahlukene kusuka kuhlobo olulula kuya kuhlobo oluyinkimbinkimbi.
✔ Ifanele izidingo zokukhiqiza ngobuningi obuhlukahlukene.
5 - Iyiphi Insimbi Nama-Alloys Ingabe i-Sand Casting Foundry yakho Isakazwa Kakhulu?
Ngokuvamile izinsimbi eziningi eziyinsimbi nezingenawo ama-alloys zingaphonswa ngenqubo yokuphonsa isihlabathi. Okwenziwe ngezinto zensimbi, i-grey cast iron, i-ductile cast iron, i-carbon steel, i-alloy steel, ithuluzi lensimbi kanye nama-alloys ensimbi angenasici kuvame ukuthelwa. Kuzinhlelo ezingezona ezomfutho, iningi le-Aluminium, iMagnesium, elenziwe ngeCopper nezinye izinto ezingafakwanga ngaphandle lingafakwa, kuyilapho i-Aluminium kanye ne-alloy yayo kungukuphonswa okusakazwa kabanzi ngesihlabathi.
I-6 - Yikuphi Ukubekezelelana Ekuphoseni Okungahle Kufinyelelwe Yisanda Sakho Esisikiwe?
The tolerances ekubunjweni zihlukaniswe ntathu Ekubunjweni Tolerances (DCT) futhi Jiyomethri Ekubunjweni Tolerances (GCT). Isisekelo sethu singathanda ukukhuluma nawe uma unesicelo esikhethekile kuma-tolerances adingekayo. Lapha kokulandelayo kukhona ukubekezelelana okujwayelekile ebangeni esingalifinyelela ngokulingiswa kwesihlabathi esiluhlaza okotshani, isikhunta ekubunjweni kwesikhunta kanye nokungabhaki i-furan resin sand casting:
✔ Ibanga le-DCT nge-Green Sand Casting: CTG10 ~ CTG13
✔ Ibanga le-DCT nguShell Mold Casting noma i-Furan Resin Sand Casting: CTG8 ~ CTG12
✔ Ibanga le-GCT nge-Green Sand Casting: CTG6 ~ CTG8
✔ I-GCT Ibanga nguShell Mold Casting noma i-Furan Resin Sand Casting: CTG4 ~ CTG7
7 - Ziyini Izikhunta Zesihlabathi?
Isikhunta sesihlabathi sisho izindlela zokubumba ezenziwe ngesihlabathi esiluhlaza noma isihlabathi esomile. Izinhlelo zokubumba isihlabathi ikakhulu zimboza ibhokisi lesihlabathi, ama-spure, ama-ingates, ama-risers, ama-cores esihlabathi, isihlabathi sesikhunta, ama-binders (uma enawo), izinto zokuphikisa nazo zonke ezinye izingxenye zesikhunta.
