Hariho uburyo bwinshi bwo gutondekanya ibishushanyo bya pulasitike, kandi birashobora kugabanywamo ibyiciro bikurikira ukurikije uburyo butandukanye bwo gukora no gutunganya ibice bya plastiki:
Urupapuro rwinshinge rwitwa kandi inshinge.Uburyo bwo kubumba iyi miterere irangwa no gushyira ibikoresho fatizo bya plastike muri barrique yo gushyushya imashini itera.Plastike irashyuha kandi igashonga, kandi igatwarwa na screw cyangwa plunger yimashini itera inshinge, yinjira mu cyuho kibumbabumbwe binyuze muri nozzle hamwe na sisitemu yo gusuka, kandi plastiki ikorwa mu cyuho kibumbwe no kubika ubushyuhe, gufata igitutu, na gukonja.Kuberako igikoresho cyo gushyushya no gukanda gishobora gukora mubyiciro, kubumba inshinge ntibishobora gusa kubumba ibice bya plastiki bifite imiterere igoye, ariko kandi bifite umusaruro mwinshi kandi byiza.Kubwibyo, gushushanya inshinge bigira uruhare runini mugushushanya ibice bya plastiki, naho inshinge zatewe hejuru ya kimwe cya kabiri cyibumba bya plastiki.Imashini yo gutera inshinge ikoreshwa cyane cyane muburyo bwa termoplastique.Mu myaka yashize, yagiye ikoreshwa buhoro buhoro mu kubumba plastiki ya termosetting.
Ifumbire yo guhunika nayo yitwa compression mold cyangwa rubber mold.Uburyo bwo kubumba buranga ubu buryo ni uko ibikoresho bya pulasitiki byongewe mu buryo butaziguye mu cyuho gifunguye, hanyuma ifunga rigafungwa.Nyuma ya plastiki iri mumashanyarazi yashizwemo nubushyuhe nigitutu, urwobo rwuzuyemo umuvuduko runaka.Muri iki gihe, imiterere ya molekulike ya plastike yabyaye imiti ihuza imiti, igenda ikomera buhoro buhoro.Ibishishwa byo guhunika bikoreshwa cyane muri plastiki ya termosetting, naho ibice bya pulasitike bibumbabumbwe bikoreshwa cyane cyane kubamo amashanyarazi hamwe nibikenerwa buri munsi.
Kwimura ibishushanyo byitwa kandi inshinge cyangwa inshinge.Uburyo bwo kubumba iyi miterere irangwa nuko ibikoresho bya pulasitiki byongewe mu cyumba cyo kugaburira mbere, hanyuma igitutu kigashyirwa ku bikoresho fatizo bya plastiki mu cyumba cyo kugaburira n’inkingi y’igitutu.Plastike yashonga munsi yubushyuhe bwinshi nigitutu kandi ikinjira mu cyuho binyuze muri sisitemu yo gusuka.Imiti ihuza imiti ibaho kandi igenda ikomera.Ihererekanyabubasha ryimikorere ikoreshwa cyane muri plastike ya termosetting, ishobora gukora ibice bya plastiki bigoye.
Extrusion ipfa nanone yitwa umutwe wa extruder.Iyi shusho irashobora guhora itanga plastike ifite ishusho imwe ihuriweho, nk'imiyoboro ya pulasitike, inkoni, n'amabati.Igikoresho cya extruder yo gushyushya no gukanda ni kimwe nicy'imashini itera inshinge.Plastike yashongeshejwe inyura mumutwe wimashini kugirango ikore igice cya pulasitiki gikomeza kubumba, gifite umusaruro mwinshi cyane.
