Hariho uburyo bwinshi bwo gutondekanya ibinyabiziga bya pulasitiki, ukurikije uburyo butandukanye bwaibice bya plastikigushiraho no gutunganya, birashobora kugabanywamo ibyiciro bikurikira.
1 - Inshinge
Uburyo bwo kubumba inshinge zirangwa no gushyira ibikoresho bya pulasitike muri barri ishyushye yimashini itera. Plastike irashyuha ikanashongeshwa, igasunikwa nicyuma cyimashini itera inshinge cyangwa plunger, hanyuma ikinjira mu cyuho kibumbabumbwe binyuze muri nozzle hamwe na sisitemu yo gusuka, kandi plastiki ikira mu cyuho kibumba binyuze mu kubika ubushyuhe, kugumana umuvuduko, no gukonjesha. Kubera ko igikoresho cyo gushyushya no gukanda gishobora gukora mubyiciro,gushushanya inshingentishobora gusa gukora ibice bya plastike bigoye, ariko kandi ifite umusaruro mwinshi kandi mwiza. Kubwibyo, kubumba inshinge bifata igice kinini mubice bya plastike, kandi inshinge zatewe hejuru ya kimwe cya kabiri cyibibumbano bya plastiki. Imashini ibumba inshinge ikoreshwa cyane cyane mugushushanya ibintu bya termoplastique, ariko mumyaka yashize nayo ikoreshwa buhoro buhoro muguhindura plastike ya termosetting.
2-Kwikuramo
Ibishushanyo byo guhunika nabyo byitwa gukanda reberi. Uburyo bwo kubumba iyi miterere irangwa no kongeramo ibikoresho fatizo bya pulasitike mu cyuho gifunguye, hanyuma ugafunga ifumbire, nyuma ya plastiki imaze gushonga bitewe nubushyuhe n’umuvuduko, yuzuza urwobo igitutu runaka. Muri iki gihe, imiterere ya molekulike ya plastike itanga imiti ihuza imiti, kandi igenda ikomera igashyiraho imiterere. Ifumbire mvaruganda ikoreshwa cyane cyane muri plastiki ya termosetting, kandi ibice bya pulasitike byabumbwe bikoreshwa cyane mugikonoshwa cyumuriro wamashanyarazi nibikenerwa buri munsi.
3-Kwimura ifumbire
Kwimura ibishushanyo nabyo byitwa extrusion mold. Inzira yo kubumba iyi miterere irangwa no kongeramo ibikoresho bya pulasitike mu cyumba cyuzuza ubushyuhe, hanyuma ugashyiraho igitutu ku bikoresho bya pulasitike mu cyumba cyuzuyemo inkingi y’umuvuduko, plastike ishonga munsi yubushyuhe bwinshi n’umuvuduko kandi ikinjira mu mwobo binyuze mu gusuka. sisitemu yububiko, hanyuma imiti ihuza imiti ibaho kandi ikira buhoro buhoro. Ihererekanyabubasha ryimikorere ikoreshwa cyane muri plastike ya termosetting kandi irashobora kubumba ibice bya plastike bifite imiterere igoye.
4 - Gukuramo bipfa
Gusohora bipfa nanone kwitwa umutwe wa extrusion. Uru rupfu rushobora guhora rutanga plastiki zifite imiterere imwe ihuriweho, nk'imiyoboro ya pulasitike, inkoni, amabati, n'ibindi. Plastike muri leta yashongeshejwe inyura mumutwe kugirango ikomeze itembera ibice bya pulasitike bibumbabumbwe, kandi umusaruro uba mwinshi cyane.
Usibye ubwoko bwavuzwe haruguru bwubwoko bwa pulasitike, hariho nububiko bwa vacuum bubumba, ibicu byumuyaga byugarije, ibishishwa byangiza, ibishushanyo bya pulasitike bifuro byinshi, nibindi.
