Ibyuma byamazi gisukwa mu mwobo kiba gifite ishusho ibereye igice, kandi nyuma yo gukomera, igice cyibice hamwe nuburyo runaka, ubunini nubwiza buboneka, bwitwa casting. Ibintu bitatu by'ingenzi: Ubugome, kwerekana imideli, gusuka no gukomera. Inyungu nini: Ibice bitoroshye birashobora gushingwa.

2. Iterambere ryo guta

Umusaruro watangiye mu 1930 ukoresheje imashini za pneumatike hamwe na gahunda yibumba.

Sima yubwoko bwicara bwagaragaye muri 1933

Mu 1944, ubukonje bukomeye bwo guhiga umucanga bwa Scan Scan yagaragaye

CO2 HARD YAKOMEYE UMUKINNYI W'UMUKINNYI wagaragaye muri 1947

Mu 1955, amabuye yubushyuhe yo gusiga umucanga

Mu 1958, Furan Resin Nta-Guteka Mold Umusenyi wagaragaye

Mu 1967, sima itemba ku mucanga wagaragaye

Mu 1968, ikirahuri cy'amazi hamwe na kama kama kugaragara

Mu myaka 50 ishize, uburyo bushya bwo gukora ibibumba nuburyo bwumubiri, nka: POLTic Pellet Molding, uburyo bwa magneic bubimbukiranya, bwatakaye uburyo bwo kubumba, nibindi byubwoko butandukanye bushingiye kubikorwa byicyuma. Nka Centrifugal Casting, igitutu kinini gitera, igitutu gito gitera, hakurya yamazi, nibindi.

3. IBIKURIKIRA

A. Guhuza n'imihindagurikire y'ibisanzwe no guhinduka. Ibicuruzwa byose. Gutera ntabwo bigarukira kuburemere, ingano nuburyo. Uburemere burashobora kuba kuri garama nke kugeza kumatori amagana, ubunini bwurukuta burashobora kuva kuri 0.3mm kugeza kuri 0m, kandi imiterere irashobora kuba ibice bigoye cyane.

B. Ibyinshi mubikoresho bibisi nibikoresho byabafasha byakoreshejwe cyane kandi bihendutse, nko guhunika igiti n'umucanga.

C. Gutakamba birashobora kunoza urwego hamwe nubunini bwubuso bunyuze mu ikoranabuhanga ryateye imbere, bityo ibice bishobora kugabanywa bike kandi bitaka.
