Ukudlulisa kuyafafuthiukufa okuqhubekayozombili izinhlobo zamathuluzi akhethekile asetshenziswa ezinqubweni zokugxiviza zensimbi ukuze alolonge futhi akhe insimbi yeshidi ibe izingxenye ezithile noma izingxenye ezithile.Kokubili ukufa kubalulekile kuzimo zokukhiqiza ngobuningi ukuze kuzuzwe ukunemba okuphezulu nokusebenza kahle.Ake sihlole uhlobo ngalunye:

1. I-Transfer Die: I-transfer die iwuhlobo lwezitembu zensimbi ezisetshenziswa emisebenzini yokugxiviza okuqhubekayo.Iqukethe iziteshi ezimbalwa noma imisebenzi eyenziwa ngokulandelana.Isici esiyinhloko sedayi yokudlulisa ukuthi ihambisa ucezu lokusebenza (imvamisa umugqa wensimbi weshidi) ukusuka kwesinye isiteshi ukuya kwesinye ngesikhathi senqubo yokugxiviza.Isiteshi ngasinye senza umsebenzi othize ku-workpiece, futhi uhlelo lokudlulisa ludlulisa isiqeshana somsebenzi phakathi kweziteshi sisebenzisa izingalo eziwumshini noma umthumeli.

Izici ezibalulekile zefa lokudlulisa:

• Amafa okudlulisa afanele izingxenye eziyinkimbinkimbi ezidinga imisebenzi eminingi kanye nokuma okunembile.
• Ziyakwazi ukukhiqiza izingxenye eziyinkimbinkimbi ezinokubekezelelana okuqinile.
• I-Transfer dies ivamise ukusetshenziswa emiqhudelwaneni yokukhiqiza enevolumu ephezulu ngenxa yokusebenza kahle kwayo namandla okuzenzakalela.
• I-workpiece ihamba phakathi kweziteshi, futhi isiteshi ngasinye singase senze imisebenzi efana nokusika, ukugoba, ukubhoboza, noma ukwenza imali.
• 

2. I-Progressive Die: I-progressive die ingolunye uhlobo lwezitembu zensimbi ezisetshenziselwa ukukhiqizwa kwevolumu ephezulu.Ngokungafani nokufa kokudlulisa, i-progressive dies igcina i-workpiece isesimweni esingashintshi phakathi nenqubo yokugxiviza.Ifa liqukethe uchungechunge lweziteshi ezenza imisebenzi elandelanayo kucezu lokusebenza njengoba ludlulela ku-die.Isiteshi ngasinye senza umsebenzi othile, futhi njengoba umsebenzi uqhubeka, kwenziwa imisebenzi emisha kuze kuqedwe ingxenye yokugcina.

Izici ezibalulekile zokufa okuqhubekayo:

• Ama-Progressive dies alungele ukukhiqiza izingxenye ezilula ukuya kwezilingene eziyinkimbinkimbi ezinomumo ophindaphindayo nezici ezifanayo.
• Asebenza kahle kakhulu ekuphakeleni okuqhubekayo kwezinto futhi adinga ukungenelela kwabasebenzisi okuncane.
• Ama-Progressive dies afaneleka kahle ukukhiqizwa okude okunomklamo wengxenye ongaguquki.
• Isiteshi ngasinye ku-dayizi sinesibopho sokwenza umsebenzi othile, njengokusika, ukugoba, ukubhoboza, noma ukubumba, njengoba umugqa uqhubeka.

Kafushane, amafa okudlulisa asetshenziselwa izingxenye eziyinkimbinkimbi ezinemisebenzi eminingi futhi kuhilela ukuhambisa ucezu lokusebenza phakathi kweziteshi, kuyilapho ama-progressive dies alungele ukukhiqiza izingxenye ezilula ukuya kwezilingene eziyinkimbinkimbi ngokuphakela okuqhubekayo nokusebenza okulandelanayo ngaphandle kokuhambisa ucezu lokusebenza.Zombili izinhlobo zokufa zibalulekile ekukhiqizeni kwanamuhla ukuze kuzuzwe ukukhiqizwa kwezingxenye zensimbi ngesivinini esikhulu sezimboni ezihlukahlukene.
