Indlela yokufanisa phakathi komkhono wangaphakathi osebenzayo womgqomo we-extrusion kanye nesikhunta kufanele kukhethwe ngokusho kokukhiqizwa kwemikhiqizo ye-aluminium alloy.Ku-extruder evundlile, izindlela ezimbili ezihambisanayo zivame ukusetshenziswa: indlela yokuvala eyisicaba, okungukuthi, ukuvala phakathi kwesilinda sokukhipha kanye nobuso bokugcina bokufa kuyindlela yokuxhumana yendiza.Izinzuzo ukuthi kulula ukucubungula, kulula ukusebenza, ingcindezi yeyunithi ekugcineni kwesikhunta kanye nolwelwesi lwangaphakathi luncane, futhi akulula ukuchotshozwa nokukhubazeka.Ububi ukuthi ukusebenza kokuvala akulungile.Uma amandla okuqinisa akwanele, noma indawo yokuxhumana ingalingani, insimbi ekhubazekile izochichima kalula ukusuka endaweni yokuxhumana ukuze yakhe "ikepisi elikhulu".
Zama ukugcina uhlaka lwe-extrusion cylinder luqinile, noma sebenzisa i-gasket ukuhlanza uhlaka ngesikhathi.Uma ithuluzi le-extrusion ligugile kakhulu noma kukhona ukungcola esihlahleni se-cylinder extrusion, i-liner yangaphakathi ayihlanzwa ngephedi yokuhlanza ngesikhathi, futhi ayishintshwa ngokuhamba kwesikhathi, izobangela ukuncipha (ekupheleni kokunye. imikhiqizo ye-extrusion, ngemva kokuhlolwa okuphansi okuphindwe kabili, kukhona into efana nophondo engxenyeni emaphakathi ye-cross-section, ebizwa ngokuthi ukuncipha).
Uma ulwelwesi lwangaphakathi lwesilinda e-extrusion lugqokwe kakhulu, isikhunta asikwazi ukumiswa ngokuqinile, okuholela eccentricity, okuzodala ukushuba kodonga olungalingani lwephrofayili ekhishwe.
