Umkhiqizi ochwepheshe wemishini yokushisa ukushisa.
I-Thermoforming kuyinqubo yokukhiqiza lapho ishidi lepulasitiki lishiselwa libe yi-a isimo esivumelana nezimo, esibe sesibunjwa noma sibunjwe kusetshenziswa isikhunta, bese kusikwa ukwenza ingxenye yokugcina noma umkhiqizo. Kokubili ukwenza i-vacuum kanye ukwakha ingcindezi izinhlobo ezahlukene zezinqubo ze-thermoforming. I Umehluko omkhulu phakathi kokwenza ingcindezi kanye nokwenza i-vacuum yi- inani lezibunjwa ezisetshenziswayo.
Ukwakhiwa kwevacuum uhlobo olulula lweipulasitiki ye-thermoforming futhi isebenzisa isikhunta futhi vacuum ingcindezi ukufeza oyifunayo ingxenye geometry. Ilungele izingxenye ezidinga kuphela ukulolongwa ngokunembile ohlangothini olulodwa, njenge ukupakishwa okuqondile kokudla noma izinto zikagesi.
Lapho ziyizinhlobo ezimbili eziyisisekelo zokubunjwa—owesilisa noma oqondile (okuyi-convex) kanye eyesifazane noma enegethivu, eyi-concave. Okwesikhunta sabesilisa, ishidi lepulasitiki ibekwe phezu kwesikhunta ukwenza uhlaka lwezilinganiso zangaphakathi ze ingxenye yepulasitiki. Ngokubunjwa kwabesifazane, amashidi e-thermoplastic abekwe ngaphakathi kwesikhunta ukuze kwakheke ngokunembile izilinganiso zangaphandle zengxenye.
Ekwakheni ingcindezi, a ishidi lepulasitiki elishisayo licindezelwa phakathi kwesikhunta ezimbili (ngakho igama), kunokuba udonswe eduze kwesikhunta esisodwa ngokumuncwa. Ingcindezi ukwakha ilungele ukukhiqiza izingxenye zepulasitiki noma izingcezu ezidinga kube nokuma okunembe kakhudlwana ezinhlangothini zombili futhi/noma kudinga umdwebo ojulile (zidinga ukunwebeka kakhulu/zijule zibe yisikhunta), njengezinto ezisetshenziswayo ama-casings adinga ukubukeka ebukeka kahle ngaphandle futhi ngena endaweni noma ulingane usayizi oqondile ohlangothini lwangaphakathi.
