Ngemuva kokuhlola nokuhlola insimbi yensimbi eyindilinga eyindilinga, ukukhiqizwa kungaqala ngokuya ngosayizi webhola lensimbi. I-steel forging ifudunyezwa ekushiseni okuthile ngokuxhumanisa nesithando somlilo ukuze kuqinisekiswe isizukulwane esisebenzayo sokuguquguquka ekufakeni; I-red-hot steel forging ithunyelwa kwisando somoya futhi icutshungulwe ngabaqhubi abanekhono. Ngemva kokuhlanganisa ibhola lensimbi eshisayo ebomvu ngokushesha ku-JUNDA imishini yokwelapha ukushisa eklanyelwe ngokukhethekile ukucisha nokwelashwa kokushisa okushisa, ukubaluleka kokuqina okuphezulu nokufana kwebhola lensimbi kungaqinisekiswa.
1.High umthelela ukuqina
2.Inhlangano ehlangene
3.Ukumelana nokugqoka okuphezulu
4.Izinga lokuphuka eliphansi
5.Ukuqina okufanayo
6.Akukho deformation
