1- Kuyini I-Shell Mold Casting?
Shell udini ekubunjweni ubizwa nangokuthi pre-camera resin isihlabathi thusi, ashisayo igobolondo udini ekubunjweni noma core ekubunjweni. Izinto zokubumba eziyinhloko isihlabathi se-phenolic resin esandulelwe ngaphambili, esibiza kakhulu kunesihlabathi esiluhlaza nesihlabathi se-furan resin. Ngaphezu kwalokho, lesi sihlabathi asikwazi ukusetshenziswa kabusha. Ngakho-ke, ukubunjiwe kwegobolondo kunezindleko eziphakeme kunokusakazwa kwesihlabathi. Nokho, Uma kuqhathaniswa green isihlabathi ekubunjweni, igobolondo ekubunjweni castings kunezinzuzo eziningi ezifana ephakeme ukubekezelelana ntathu, okuhle ebusweni izinga nokukhubazeka esingaphansi ekubunjweni. Inqubo yokubumba igobolondo ilungele ngokukhethekile ukukhiqiza ukusakazwa kobujamo obunzima, imikhumbi yengcindezi, isisindo esibucayi nokujikijela okudinga ukuqeda okuphezulu.
2- Yiziphi Izinyathelo zeShell Mold Casting?
✔ Ukwenza Amaphethini Wensimbi. Isihlabathi se-resin esifakwe ngaphambili sidinga ukufudunyezwa emaphethini, ngakho-ke amaphethini wensimbi ayithuluzi elidingekayo lokwenza ama-Shell molding castings.
✔ Ukwenza Isikhunta Sesihlabathi Esivele Sigcwele. Ngemuva kokufaka amaphethini wensimbi emshinini wokubumba, isihlabathi se-resin esenziwe ngaphambili sizodutshulwa emaphethini, futhi ngemuva kokushisa, ukumbozwa kwe-resin kuzoncibilikiswa, bese isikhunta sesihlabathi siba yigobolondo lesihlabathi eliqinile nezinsimbi.
✔ Ukuncibilikisa i-Cast Metal. Kusetshenziswa iziko lokungeniswa, izinto zizoncibilika zibe wuketshezi, bese izingxube zamakhemikhali zensimbi ketshezi kufanele zihlaziywe ukufanisa izinombolo namaphesenti adingekayo.
✔ Ukuthela Insimbi. Lapho insimbi encibilikile ihlangabezana nezidingo, khona-ke zizothululelwa kwisikhunta segobolondo. Ngokuya ngezinhlamvu ezahlukahlukene zomklamo wokusakaza, isikhunta segobolondo sizofihlwa esihlabathini esiluhlaza noma sihlanganiswe izingqimba.
✔ Shot Blasting, Ukugaya nokuhlanza. Ngemuva kokupholisa nokuqina kokuphosa, ama-risers, amasango noma i-iron eyengeziwe kufanele anqunywe futhi asuswe. Ngemuva kwalokho ukukhishwa kwensimbi kuzohlanzwa ngemishini yokuhluza isihlabathi noma ngemishini yokudubula. Ngemuva kokugaya ikhanda lokugoqa kanye nolayini bokuhlukanisa, izingxenye eziqediwe zokusakaza zazizofika, zilinde ezinye izinqubo uma kudingeka.
3- Yiziphi Izinzuzo Zesikhunta Sokulingisa Ukulingisa?
✔ Ukugoqwa kweShell-isikhunta ngokuvamile kunembile ngokwedlula ukwakheka kwesihlabathi.
✔ Indawo ebushelelezi yokusakazwa okuqediwe ingatholwa ngokusakazwa kwegobolondo.
✔ Ama-engeli okusalungiswa aphansi kunokuphonswa kwesihlabathi kuyadingeka ekubunjweni kwesikhunta segobolondo.
Ukungena kwegobolondo kuphakeme ngakho-ke kufakwa igesi engaphansi noma engekho.
✔ Inqubo yesikhunta se-Shell idinga inani elincane kakhulu lesihlabathi.
✔ Ukwenza imishini kungenzeka kalula ngenxa yokucubungula okulula okuhilelekile ekubunjweni kwegobolondo.
4- Yiziphi Izinsimbi Nama-Alloys Okungasakazwa Yinqubo Yokulingisa I-Shell Mold?
