Ipayipi lensimbi elishisayo elikhishweisetshenziselwa ukukhiqizwa kwenqubo ye-hot extrusion ukwenza amashubhu ensimbi angenamthungo.

I-extrusion eshisayo isetshenziswa kabanzi ekukhiqizeni i-aluminium, ithusi namanye amapayipi ensimbi yensimbi namaphrofayili.I-extrusion eshisayo yensimbi yokukhiqiza kokubili amapayipi akhethekile namaphrofayili, kunzima ukusetshenziselwa ukukhiqizwa kwe-extrusion ebandayo noma i-extrusion yesikhungo esiqinile nesifudumele somgodi (ngembobo noma imbobo eyimpumputhe) i-carbon steel kanye nezingxenye zensimbi ye-alloy, ezifana njengenduku enekhanda eliwugqinsi, umgqomo, iziqukathi, njll. I-extrusion eshisayo yokunemba kwe-dimensional kanye nokuqedwa kwengaphezulu kungcono kunezingxenye ezishisayo zokubumba, kodwa kusadingeka kudlule nengxenye yokuqedela okuvamile noma ukukhanda.

Ubuchwepheshe be-extrusion obushisayo buwuhlobo lwensimbi ngaphezu kokushisa kwe-recrystallization ye-extrusion, i-tube billet evela ku-extrusion yokufa, ukuze uthole indlela yokufa yokufa kwengxenye yepayipi yensimbi yokwakha.Enqubweni ye-extrusion eshisayo (kusuka epayipini ukuya kushubhu ye-arakawa), i-tube billet i-deformation ngaphansi kokuthathu kuya esimweni sokucindezeleka esicindezelayo.Lokhu akukwazi nje kuphela ukuxazulula inkinga yokwakheka kwepayipi lensimbi elingagugi, kodwa futhi kungagwema amashubhu ngaphakathi nangaphandle kokukhubazeka okubangelwa ukucindezeleka okuqinile.Ngakho indlela yokubumba eshisayo ye-extrusion ifaneleka ngokukhethekile kuzo zonke izinhlobo zensimbi ye-alloy, engenasici
