Kwinqanaba lokwenza i-mold, siya kwenza i-mold ngokusekelwe kuyilo lokugqibela lwemveliso. Oku kukulungiselela imveliso enkulu, ukuqinisekisa ukuba imveliso nganye igcina ukuhambelana kunye nezinga eliphezulu lomgangatho.
Unikezelo lwenkonzo:
Iimbumba zeemveliso ezenziwe ngokwezifiso zokuqinisekisa ukuthotyelwa koyilo kunye nemigangatho yemveliso.
Uvavanyo lokungunda lokuqala kunye nohlengahlengiso ukuqinisekisa imveliso egudileyo.
