Ukukhipha i-aluminium ngokucindezela: Izinduku, amashubhu namaphrofayela
Cishe yonke induku, ishubhu, i-engeli nephrofayela ye-T-slot ye-aluminium kukhishwa ngokucindezela: isilinda se-aluminium, i-billet, sishiswa sifike cishe ku-350–500 °C, sifakwe esitsheni esinezindonga eziwugqinsi bese siphushwa ngumshini ophushayo sidlule ku-die yensimbi enembobo emise njengomkhiqizo, njengokhilimu wamazinyo ophuma eshubhwini. Imishini yokucindezela isukela cishe kumathani angu-230 kuya ku-11,000. Izimo ezingenalutho phakathi njengeshubhu zidlula zizungeza i-mandrel noma zidlula ku-die ehlukanisa insimbi bese iphinde iyihlanganise. Ingxenye ende ekhishiwe iyapholiswa, idonswe ukuze iqonde, isikwe ngobude futhi, kuma-alloy aqinile, ilashwe ngokushisa.
Lena inqubo yezimboni; ichaza ukuthi impahla abakhi abayithengayo yenziwa kanjani.

Ama-ingot e-aluminium ayancibilikiswa futhi nezengezo ze-alloy bese athelwa njengezingodo ezinde eziyindilinga, bese esahwa abe ama-billet.

I-billet ngayinye ishiswa ifike cishe ku-350–500 °C, ithambe ngokwanele ukuze igeleze kodwa ingaphansi kakhulu kwezinga lokuncibilika.

I-billet ingena esitsheni somshini phambi kwe-die; umshini ophushayo uyiphusha idlule ngokucindezela okungamashumi kuya emakhulwini ama-megapascal. Imbobo ye-die inquma iphrofayela.

Ama-blueprint ahlobene
Lama-blueprint abelana ngolwazi — amasu, izinto noma izimiso
CC0 Isizinda Somphakathi
Le blueprint ikhishwe ngaphansi kwe-CC0. Ukhululekile ukukopisha, ukuguqula, ukusabalalisa, nokusebenzisa ngaphandle kwemvume.
Sekela uMenzi ngokuthenga imikhiqizo nge-Blueprint yabo IKhomishane Yomenzi kumiswe ngabathengisi, noma dala inguqulo entsha yale Blueprint bese uyifaka njengoxhumaniso ku-Blueprint yakho ukuze wabelane ngemali engenayo.
