Gukuramo plastike, bizwi kandi nka plasitike yo gukuramo, ni uburyo bukomeza bwo gukora ibintu byinshi aho ibikoresho bya termoplastique - muburyo bwa poro, pellet cyangwa granules - bishonga kimwe hanyuma bigahita biva mubishusho bipfa hakoreshejwe igitutu. Mugukuramo screw, igitutu kiva mukuzunguruka kwa screw kurukuta rwa barriel. Iyo gushonga kwa plastiki kunyura mu rupfu, bigira imiterere yumwobo bipfa gusiga extruder. Ibicuruzwa byakuwe hanze byitwa extrudate.
Ubusanzwe extruder igizwe na zone enye:
Ahantu ho kugaburira
Muri iyi zone, ubujyakuzimu bwindege burahoraho. Intera iri hagati ya diameter nini hejuru yindege na diameter ntoya ya screw hepfo yindege ni ubujyakuzimu bwindege.
Inzibacyuho cyangwa Agace ko guhunika
Ubujyakuzimu bw'indege butangira kugabanuka muri iyi zone. Mubyukuri, ibikoresho bya thermoplastique birahagarikwa kandi bitangira gukora plastike.
Agace kavanze
Muri iyi zone, ubujyakuzimu bwindege burahoraho. Kugirango ibikoresho bishonge rwose kandi bivanze kimwe, ikintu kidasanzwe cyo kuvanga gishobora kuba kiri.
Agace k'ibipimo
Iyi zone ifite ubujyakuzimu buto ugereranije no kuvanga ariko bikomeza guhoraho. Nanone, igitutu gisunika gushonga binyuze muri shaping bipfa muri iyi zone.
Ku rundi rwandiko, gushonga kwa polymer bivanze biterwa nibintu bitatu byingenzi:
Kwimura Ubushyuhe
Ihererekanyabubasha nimbaraga ziva muri moteri ya extruder ikajya muri shaft ya extruder. Nanone, gushonga kwa polymer bigira ingaruka kumurongo wa screw nigihe cyo gutura.
Ubuvanganzo
Ibi bizanwa no guterana imbere kwa poro, umwirondoro wa screw, umuvuduko wa screw, nigipimo cyibiryo.
Extruder Barrel
Ibice bitatu cyangwa byinshi byigenga byubushakashatsi bikoreshwa mukubungabunga ubushyuhe bwa barriel.
