Kukho amanyathelo ama-5 okwenza iimveliso zokuphosa.
Inyathelo 1: Lungisa ukungunda.Ukufudumeza isikhunta kwiqondo elithile lobushushu kwaye emva koko utshize i-interiors ye-mold kunye ne-refractory coating okanye i-lubricant.
Inyathelo 2: Tofa imathiriyeli.Ukugalela isinyithi esityhidiweyo kwi-mold phantsi koxinzelelo olufunekayo.
Inyathelo lesi-3: Pholisa intsimbi.Nje ukuba isinyithi esinyibilikisiweyo sitofwe emngxunyeni, thatha ixesha ukuyiyeka iqine
Inyathelo lesi-4: Khupha umngundo.Khulula ukungunda ngononophelo kwaye ukhuphe indawo etyhidiweyo.
Inyathelo 5: Sika inxalenye yokuphosa.Isinyathelo sokugqibela kukususa imiphetho ebukhali kunye nezinto ezongezelelweyo ukwenza icandelo elifunwayo imilo.
I-zinc, i-aluminium kunye ne-magnesium.Kwakhona, unokukhetha ubhedu, ubhedu, kwiindawo zokuphosa ngokwesiko.
Ewe, iqondo lobushushu liyinto ebaluleke kakhulu ekwenzeni isinyithi.Ukushisa okufanelekileyo kunokuqinisekisa ukuba i-alloy yensimbi ishushu ngokuchanekileyo kwaye iqhubeleka ngokuqhubekayo kwi-mold.
Akukho mpendulo izinzileyo.Iindawo zokugalela ngokuqhelekileyo ziveliswa kusetyenziswa i-aluminiyam, i-zinc kunye ne-magnesium engenziwanga kakhulu kwintsimbi, eyenza ukuba i-corrosion resistant kunye ne-rust.Kodwa ukuba awuzikhuseli kakuhle iimveliso zakho ixesha elide, kunokwenzeka ukuba ziya kuhlwa.
