Izici zenqubo:I-Yuchai's first thin-walled lightweight cylinder block eyenziwe nge-vermicular iron e-China VI yenziwe nge-RuT400 esikhundleni se-HT250 yakudala, futhi amandla omzimba we-cylinder enyuswe ngo-60%. Ubukhulu odongeni obuphansi bungama-4±0.75mm, futhi isisindo somkhiqizo sincishiswe ngo-17%. Ukwenza imikhiqizo ibe lula kufeziwe. Inqubo yokugqoka i-iron sand isetshenziselwa ukukhiqiza. Kuyo yonke inqubo yokukhiqiza, i-robot isetshenziselwa ukukhipha i-coring, ukuhlanganisa i-core, ukugqoka i-dip-coating kanye nokubeka i-core ukuthuthukisa ukunemba kwe-dimensional kwezingxenye ezincane zodonga. Isoftware yokuhlaziya ukusakazwa kwe-MAGMA casting isetshenziselwa ukwenza kahle uhlelo lokusakaza, futhi i-CAE isetshenziselwa ukuhlaziya isakhiwo somkhiqizo olungasindi.
