Izigqibo zokubethelwa kwesinyithi - uhlobo lokufa, ibakala lentsimbi, ukukhutshwa, kunye noqeqesho lokugcinwa - i-compound ngaphezulu kwezigidi zeemveliso. Ukufumana ezi zichanekileyo kwinqanaba lokuyila kubiza iqhezu lexabiso lexabiso eliphakathi kwimveliso kwi-scrap, ixesha lokuphumla, kunye nokuphinda usebenze ngokukhawuleza.
Iinjineli ezichaza isixhobo esitsha: i-match die architecture ukuya kumthamo kunye nenxalenye yejometri, khetha eyona ntsimbi inexabiso eliphantsi ehlangabezana nethagethi yakho yobomi, kwaye uqhube uluhlu lokugcinwa kweshedyuli kwishedyuli. Kumaqela okuthenga avavanya abaniki-nkonzo: buza malunga nemigaqo yogcino lwabo, ukufunwa kwentsimbi, kunye nokulandelela ubomi bokufa - aba baboneleli bahlukeneyo bazisa iinxalenye ezingaguqukiyo kwabo bazisa ezingangqinelaniyo.
Ngaba ukulungele ukuxoxa ngeprojekthi yakho elandelayo yokufakwa kwesitampu? Qhagamshelana neqela lethu lobunjineli kuphononongo lwezixhobo kunye nokucaphula.
