Isilinganisoesisindayo I-steel shot iyinto ebalulekile yokusekela nokupholisa enqubweni yokuthulula i-coated sand shell. Ayisetshenziselwa ukwelapha ubuso, kodwa igcwaliswa phakathi kwesikhunta sesihlabathi (i-shell mold) nebhokisi lesihlabathi ngesikhathi sokuthulula, isebenza ukuqinisa ukusekela nokusiza ekupholiseni.

Okuwumbhalo omanzi wezobuchwepheshe mayelana nensimbi yebhokisi elingcwatshwe:

 Umsebenzi Oyinhloko kanye Nenqubo

· Umsebenzi oyinhloko: Njengokugcwalisa ukusekela isikhunta sesihlabathi esincanyana, ukuvimbela ukugoba noma ukuqhekeka ngesikhathi sokuthela.

· Inqubo evamile: Beka isikhunta esilungisiwe ebhokisini lesihlabathi, ugcwalise ngensimbi ezungezile bese uyazihlanganisa, bese uthela into encibilikisiwe. Izinsimbi zihambisa ukushisa ngokushesha ukuze kusheshiswe ukuphola.

· Izinsimbi ezifanele: Zifanele izinsimbi ezincane nezimaphakathi ezisezingeni eliphezulu njenge-crankshafts, hubs, gears, kanye nezingxenye eziyinkimbinkimbi ezinodonga oluncane njengezindlu zenjini kanye nezembozo zezimoto.

Izici Zomzimba Nezamakhemikhali

· Umumo nobuso: Iningi liyizinhlayiya eziyindilinga, ubuso buvame ukufakwa ugesi ukuze kugwenywe ukugqwala.

· Ukwakheka kwamakhemikhali: Impahla i-cast iron noma i-alloy.

· Ikhabhoni (C): 1.2 - 1.5%

· I-Manganese (Mn): 0.02 - 0.1%

· I-Silicon (Si): 0.01 - 0.1%

· Isulfure (S): ≤ 0.40%

· I-Phosphorus (P): ≤ 0.30%

· Imininingwane Yomzimba: Izilinganiso ezijwayelekile zingu-1.0 - 10mm; ubukhulu bungaba ngu-6.7 - 7.2 T/m³; isisindo esiyisisekelo singaba ngu-4.2 - 4.5 T/m³.
