1. Influens bilong ol samting long kwaliti bilong ol dai kasting. Ol samting i save makim ol samting tasol (raw materiel) na ol helpim samting (inkludim ol samting bilong yusim).
2. Hevi bilong ol raw materiel i no skelim long taim bilong smelting. Proporsen bilong ol raw materiel i kamap klia olgeta long ekspiriens bilong opereta. Ol mistek long mesamen bilong kaikai bai kamapim ol hevi olsem liklik molten ain tempereja na oksidesen bilong ain i tanim, we bai mekim kwaliti bilong dai kastings i no stap gut. .
3. Rilesensip namel long ol proses rot na kwaliti bilong ol dai kastings. Ol fektori i gat ol teknikel infomesen i stret olsem ol proses regulesen, opereting instraksen, metalujikel teknikel kondisen, prodak teknikel kondisen, na prodak akseptesen teknikel kondisen. Eni senis bai senisim kwaliti bilong dai kasting.
4. Influens bilong ol tul ikwipmen long kwaliti bilong ol dai kasting, olsem ol dai kasting masin, melting oven, mol, pinga pres rum, injeksen piston, ol samting bilong stretim, ol tul, ol tul bilong skelim, na ol narapela samting.
5. Nogut win permeability bilong molding sand bai mekim ol kasting i kamap long ol pores i gat ol pores. Liklik strong bilong molding wesan bai mekim kasting i bruk. kwaliti bilong ol kasting i no gutpela tumas bikos long nogut kasting wesan.
