Uyini Umehluko Phakathi Kokwenza I-Vacuum, I-Thermoforming, kanye Nokwenza Ingcindezi?

I-Thermoformingkuyinqubo yokukhiqiza lapho ishidi lepulasitiki lishiselwa libe yisimo esivumelana nezimo, esibe sesibunjwa noma sakhiwe kusetshenziswa isikhunta, bese siyasikwa ukwenza ingxenye yokugcina noma umkhiqizo. Kokubili ukwakhiwa kwe-vacuum kanye nokwenza ingcindezi kuyizinhlobo ezahlukene zezinqubo ze-thermoforming. Umehluko omkhulu phakathi kokwenza ingcindezi kanye nokwenza i-vacuum yinani lezibunjwa ezisetshenziswayo.

Ukwakhiwa kwevacuumiwuhlobo olulula kakhulu lwe-thermoforming yepulasitiki futhi isebenzisa isikhunta nengcindezi ye-vacuum ukuze kuzuzwe ingxenye yejiyomethri oyifunayo. Ilungele izingxenye ezidinga kuphela ukulolongwa ngokunembile ohlangothini olulodwa, njengokupakishwa kwe-contour yokudla noma izinto zikagesi.

Kunezinhlobo ezimbili eziyisisekelo zokubunjwa—owesilisa noma oqondile (okuyi-convex) nowesifazane noma onegethivu, okuyi-concave. Esikhunjeni sabesilisa, kufakwa ishidi lepulasitiki esikhunjeni ukuze kwakheke uhlaka lwezilinganiso zangaphakathi zengxenye yepulasitiki. Ezikhunjini zesifazane, amashidi e-thermoplastic afakwa ngaphakathi kwesikhunta ukuze enze ngokunembile ubukhulu bengxenye yangaphandle.

Ekwakhekeni kwengcindezi, ishidi lepulasitiki elishisayo licindezelwa phakathi kwesikhunta ezimbili (yingakho igama), kunokuba lidonswe eduze kwesikhunta esisodwa ngokumuncwa. Ukwakhiwa kwengcindezi kulungele ukukhiqiza izingxenye zepulasitiki noma izingcezu ezidinga ukulolongwa ngokunembe kakhudlwana nhlangothi zombili futhi/noma zidinga ukudonsa okujulile (zidinga ukunwebeka kakhulu/zijule zibe isikhunta), njengama-casings kagesi adinga ukubukeka ngendlela ebukekayo. ngaphandle bese uchofoza endaweni noma ulingane nosayizi oqondile ohlangothini lwangaphakathi.
