Gushushanya ni inzira yo gukora uburyo butandukanye bwa polymers (ifu, pellet, ibisubizo cyangwa gutatanya) mubicuruzwa muburyo bwifuzwa. Nibyingenzi muburyo bwose bwo kubumba ibikoresho bya pulasitike kandi ni umusaruro wibikoresho byose bya polymer cyangwa imyirondoro. Inzira ikenewe.Uburyo bwo kubumba plastike burimo gushushanya ibicuruzwa, gushushanya inshinge, kubumba compression, kubumba kwimura, kubumba laminate, kubumba, guhindagura kalendari, kubumba ifuro, kubumba hamwe nubundi buryo bwinshi, byose bifite aho bihurira.
Thermoformingni uburyo bwo gukora ibicuruzwa ukoresheje impapuro za thermoplastique nkibikoresho fatizo, bishobora guterwa no kubumba kwa kabiri kwa plastiki. Ubwa mbere, urupapuro rwaciwe mubunini nubunini rushyirwa kumurongo wububiko, hanyuma rushyutswe kumurongo muremure hagati ya Tg-Tf, urupapuro rurambuye mugihe rushyushye, hanyuma hashyirwaho igitutu kugirango rufunge Kuri Ifumbire Imiterere isa nubuso bwubuso, kandi ibicuruzwa birashobora kuboneka nyuma yo gukonjesha, gushushanya no gutema.Mugihe cya thermoforming, umuvuduko ukoreshwa ushingiye ahanini kubitandukaniro ryumuvuduko ukorwa no guhumeka no kwinjiza umwuka wugarije kumpande zombi zurupapuro, ariko nanone hakoreshejwe ingufu za mashini hamwe nigitutu cya hydraulic.
Ikiranga thermoforming nuko igitutu cyo gukora ari gito, kandi inzira ya thermoforming nuburyo bukurikira:
ikibaho (urupapuro) ibikoresho → gufatisha → gushyushya → igitutu → gukonja → gushiraho products ibicuruzwa byarangije igice → gukonjesha → gutema.Thermoforming yibicuruzwa byarangiye bitandukanye na tekinoroji yo gutunganya inshuro imwe nko guterwa inshinge no kuyisohora. Ntabwo ari kububiko bwa pulasitike cyangwa pellet zo gushyushya ibumba cyangwa guhora ubumba hamwe nigice kimwe binyuze mu rupfu; eka kandi ntabwo ikoresha ibikoresho byimashini, ibikoresho nubundi buryo bwo gutunganya imashini kugirango ugabanye igice cyibikoresho bya plastiki. Ibikurikira, kugirango ubone imiterere nubunini busabwa, ariko kubikoresho bya plastiki (urupapuro), gushyushya, ukoresheje ifu, vacuum cyangwa igitutu kugirango uhindure ibikoresho (urupapuro). Kugera kumiterere nubunini busabwa, byunganirwa nuburyo bwo gushyigikira, kugirango umenye intego yo gusaba.
Tekinoroji ya thermoforming yatejwe imbere ishingiye kuburyo bwo gukora impapuro. Nubwo igihe cyiterambere cyacyo atari kirekire, ariko umuvuduko wo gutunganya urihuta, urwego rwo kwikora ruri hejuru, ifu ihendutse kandi yoroshye kuyisimbuza, kandi guhuza n'imikorere birakomeye. Irashobora gutanga ibicuruzwa binini nk'indege n'ibice by'imodoka, bito nkibikombe byibinyobwa. Ibisigara biroroshye kubisubiramo. Irashobora gutunganya impapuro zoroshye nka 0,10mm z'ubugari. Izi mpapuro zirashobora kuba mucyo cyangwa zidasobanutse, kristaline cyangwa amorphous. Ibishushanyo birashobora gucapishwa kurupapuro rwambere, cyangwa ibishushanyo bifite amabara meza birashobora gucapurwa nyuma yo kubumba.
Mu myaka 30 kugeza kuri 40 ishize, kubera ubwinshi bwibikoresho bya shitingi (urupapuro) bigenda byiyongera nkibikoresho fatizo, gukomeza kunoza ibikoresho bitunganyirizwamo imiti, hamwe no gukoresha ibicuruzwa byinshi, tekinoroji ya thermoforming yateye imbere Hamwe niterambere ryihuse, ikoranabuhanga ryaryo n'ibikoresho bigenda birushaho kuba byiza. Ugereranije no gushushanya inshinge, thermoforming ifite ibyiza byo gukora neza cyane, uburyo bworoshye, gushora ibikoresho bike, hamwe nubushobozi bwo gukora ibicuruzwa bifite ubuso bunini. Nyamara, ikiguzi cyibikoresho bya termoforming ni byinshi, kandi hariho inzira nyinshi zo gutunganya ibicuruzwa. Hamwe niterambere ryiterambere ryiterambere ryikoranabuhanga kandi rikeneye inyungu nyinshi mubukungu, ibikoresho bya thermoforming byagiye bivanaho ibyahozeho gusa nka sisitemu yigenga ya plastike yigenga (urupapuro), kandi yatangiye guhuza nibindi bikoresho byabyara umusaruro kugirango ihuze ibiyigize. Umurongo wuzuye wibikorwa bikenewe, bityo ukarushaho kunoza umusaruro no kugabanya igiciro cyibicuruzwa byanyuma.
Thermoformingirakwiriye cyane cyane gukora ibicuruzwa bifite inkuta zoroheje hamwe nubuso bunini. Ubwoko bwa plastike bukunze gukoreshwa burimo polystirene, plexiglass, polyvinyl chloride, abs, polyethylene, polypropilene, polyamide, polyakarubone na polyethylene terephthalate.
