Ukuhanjiswa: iintsuku ezi-7-15 emva kwentlawulo.
Umphezulu: Iityhubhu ziza kuvanishi (Ngaphandle kuphela) ukunqanda umhlwa.
Ukumakishwa: iBanga eliMgangatho + leNsimbi + Ubungakanani + Ubushushu Hayi + iLoti yeNombolo.
Ukupakishwa: Iinyanda (ezinehexagonal), iibhokisi zoMthi, iiCreyithi (intsimbi/umthi) okanye njengoko kufuneka.

Iindlela Zokuvelisa

(1)Indlela yokwenza intsimbi
Isinyithi senziwa ngesithando sombane, isiguquli seoksijini okanye indlela yokuvula iziko.

(2)Indlela yokwenziwa kwetyhubhu engenanto
I-tube engenanto inokuveliswa ngendlela eshushu, kunye ne-billet eqhubekayo yokuphosa okanye i-ingot yensimbi nayo ingasetyenziswa.

(3)Indlela yokuvelisa umbhobho wentsimbi
Umbhobho wensimbi unokuveliswa ngokutshisa okutshisa (i-extrusion, isandiso) okanye umzobo obandayo (i-rolling) indlela engenamthungo.

Uvavanyo

(1)Uvavanyo lwe-hydraulic
Umbhobho wentsimbi kufuneka uvavanywe nge-hydraulically nganye nganye.

(2)Uvavanyo oluthambileyo
Imibhobho yentsimbi enobubanzi obungaphandle obungaphezulu kwe-22mm ukuya kwi-400mm kunye nobukhulu bodonga obungekho ngaphezu kwe-10mm iya kufakwa kuvavanyo lokucaba.

(3)Uvavanyo oluvuthayo
Umbhobho wensimbi kunye nobukhulu bodonga obungekho ngaphezu kwe-8 mm unokuvavanywa kwi-flare test kunye ne-taper ephezulu ye-30 °, 45 ° okanye 60 °.

(4) Uvavanyo lokugoba
Imibhobho yentsimbi enobubanzi obungaphandle obungekho ngaphezu kwe-22 mm iya kufakwa kuvavanyo lokugoba.

(5)Uvavanyo olungonakalisi
Ngokweemfuno zomthengi, umbhobho wensimbi uya kuvavanywa nge-ultrasonically nganye.

Umgangatho womphezulu

Indawo yangaphakathi nangaphandle yombhobho wensimbi ayinayo i-cracks, i-folds, i-creases, i-crusting okanye ukwahlukana, kwaye ezi ziphene kufuneka zisuswe ngokupheleleyo.Ubunzulu bokucoca abuyi kudlula ukutenxa okungalunganga kobunzima bodonga lwegama, kwaye ubukhulu bodonga lokwenene kwindawo yokucoca abuyi kuba ngaphantsi kobuncinci obuvunyelwe ludonga.
