Mu buryo bunini kandi bugoye bwo gutunganya polimeri, aho imashini zigezweho zikunze gufata umwanya munini, ikiyunguruzo cya rubber gikora nk'umurinzi utuje kandi w'ingenzi kandi ufite ubuziranenge. Iyi mashini ikomeye kandi isa n'aho yoroshye igira uruhare runini mu kwemeza ko rubber ikora neza, ihamye kandi ikora neza, bigatuma iba inkingi ikomeye mu gukora ibicuruzwa bya rubber.
Mu by’ingenzi, akazi k’icyuma gisukura umupira, cyangwa icyuma gisukura umupira, ni ukuyungurura. Intego yacyo y’ibanze ni ugukuraho imyanda—nk’ibice by’icyuma, uduce twa raba tutavuwe, imigozi yo gufunga, cyangwa utundi duce tw’inyuma—mu gice cy’icyuma cyashyizwemo umupira mbere yuko gihinduka impapuro, uduce duto, cyangwa imiterere ya nyuma. Kwinjizwamo imyanda mito cyane bishobora gutuma ibicuruzwa byarangiye binanirwa, bigatera ahantu hadakomeye, amapine agacika, insinga z’amashanyarazi zangirika, cyangwa inenge mu byuma bifunga by’ubuvuzi. Bityo, icyuma gisukura gikora nk'umurongo wa nyuma w’uburinzi mu kugenzura ubuziranenge.
Imiterere y'iyi mashini ifite intego nziza. Ubusanzwe igizwe n'agasanduku gakomeye gafite vis ikomeye. Agasanduku gakozwe mu buryo buvanze gashyirwa mu gasanduku, aho agasanduku gashyirwa mu gikoresho cya pulasitiki kakagashyira mu buryo bukomeye mu ihuriro ry'ingenzi: isahani igabanya ubushyuhe n'agasanduku k'icyuma. Agasanduku k'icyuma gakozwe mu buryo bw'icyuma gafite imiyoboro mito (ikunze kuva kuri mesh 20 kugeza ku 100), imashini zivanga ibikoresho byo mu rwego rwa laboratwari, ni wo mutima w'inzira yo kuyungurura. Uko agasanduku gashyizwemo umwuka gashyirwa mu buryo bukabije muri utu dusanduku duto, imyanda ikomeye irafatwa. Agasanduku kayunguruwe gahita kanyura mu mutwe w'icyuma kagakora umugozi ukomeza cyangwa ishusho runaka, hanyuma gakonjeshwa ku gikoresho gikonjesha.
Utwuma duto twa rubber dukoreshwa mu buryo bw'ikoranabuhanga twubatswe kugira ngo twihanganire imimerere igoye cyane. Tugomba guhangana n'umuvuduko mwinshi, akenshi urenga 300 bar, ukorwa no gushyira rubber mu cyuma gishyushye. Kugira ngo tubigereho, dufite imiterere ikomeye ifite imigozi ikomeye n'udupira duto. Igishya cy'ingenzi ni ubushobozi bwo gukora buri gihe. Utwuma duto twagombaga gufungwa kugira ngo dusukure intoki. Moderi zigezweho zikoresha uburyo bwa dual-piston cyangwa slide-plate butuma agasanduku k'icyuma gahindurwa cyangwa gasukurwa nta kubangamira amazi, bikongera cyane imikorere n'ubuziranenge.
Uburyo bwo gukurura irangi buri ku isi hose mu nganda. Ni ingenzi cyane mu gukora amapine ku rukuta rw'inyuma, ku rukuta rw'imbere, no ku ruhu rw'imbere. Ibikoresho bya tekiniki bikora neza cyane nk'imiyoboro, imikandara, n'ibikoresho bifasha mu kuvura uruhu bishingiye ku bikoresho bifasha mu kuvura imiterere y'urukuta. Ahari ikintu cy'ingenzi cyane, uruganda rukora imigozi ya rubingo, rushobora kuganirwaho mu gukora ibikoresho by'ubuvuzi, ibiryo, n'ibikomoka ku isuku, aho isuku ari yo ihambaye cyane.
Uretse gukuraho ubwandu gusa, imashini itwikira imipira, ikiyunguruzo kinafasha mu guhuza ibicuruzwa. Gukata no gushyushya cyane bihuza imvange ya mipira, bigatuma ibintu bihinduka neza kandi bigakwirakwira mu buryo buhoraho. Ibi bituma habaho kunoza uburyo bwo gutunganya ibintu mu buryo bukurikira nko gushushanya cyangwa gushushanya, gutwikira imipira ya silicone ku mashini zikora imyenda, kugabanya imyanda no kongera imiterere y'ibicuruzwa bya nyuma.
Mu gusoza, ikiyunguruzo cya rubber si ikintu cyoroshye cyane kuruta akayunguruzo. Ni ingenzi mu kwemeza umutekano, ubwizerwe, n'ubuziranenge mu gukora rubber. Gukora kwayo mu buryo buhoraho mu bihe bibi bituma ibikoresho bigezweho byakozwe muri laboratwari bihinduka ibicuruzwa byizewe mu isi nyayo. Nubwo bishobora kubura uburyohe bw'ibikoresho bimwe na bimwe byo mu nzira, uruhare rwayo ntirushobora gusimburwa—intwari nyayo idashimwa, irinda bucece ubusugire bw'ibice byinshi bya rubber bigize urufatiro rw'ubwikorezi bwa none, inganda, n'ubuzima bwa buri munsi.
