Inzira z'amakara ni inzira zikozwe mu bikoresho bya karaba n'ibisuguti, zikoreshwa cyane mu mashini z'ubwubatsi, imashini z'ubuhinzi n'ibikoresho bya gisirikare.

Isesengura ry'uko urwego rw'inganda zikora imipira ya kawa rubi ruhagaze ubu

Inzira za kabuturabyakozwe bwa mbere na The Japanese Bridgestone Corporation mu 1968. Byakozwe mbere kugira ngo bifashe inzira z'ubuhinzi zivanze n'ibyuma bifunganye byoroshye gupfukiranwa n'ibyatsi, ibyatsi by'ingano n'umwanda, amapine ya kabutike agwa mu mirima y'ubuhinzi, n'inzira z'ibyuma zishobora kwangiza inzira za kaburimbo na sima.

Inzira y'umupira w'amaguru yo mu BushinwaImirimo yo guteza imbere yatangiye mu mpera za 1980, yabereye i Hangzhou, Taizhou, Zhenjiang, Shenyang, Kaifeng na Shanghai n'ahandi, yashoboye guteza imbere imashini zitandukanye z'ubuhinzi, imashini z'ubuhanga n'imodoka zitwara imizigo ku buryo butandukanye, kandi yashyizeho ubushobozi bwo gukora ibintu byinshi. Mu myaka ya 1990, Zhejiang Linhai Jinlilong Shoes Co., Ltd. yateguye kandi itanga uburenganzira ku giti cy'inzira y'icyuma idahuza imigozi, yashyizeho urufatiro rw'inganda z'inzira z'umugozi mu Bushinwa kugira ngo zirusheho kunoza ireme, zigabanye ikiguzi kandi zongere ubushobozi bwo gukora.

Kugeza ubu, mu Bushinwa hari inganda zirenga 20 zikora imiyoboro ya rubber, kandi icyuho kiri hagati y’ubwiza bw’ibicuruzwa n’ibicuruzwa byo mu mahanga ni gito cyane, kandi gifite inyungu ku giciro runaka. Ibyinshi mu bigo bikora imiyoboro ya rubber biri i Zhejiang. Hagakurikiraho Shanghai, Jiangsu n’ahandi. Mu bijyanye n’ikoreshwa ry’ibicuruzwa, imiyoboro ya rubber y’imashini z’ubwubatsi ikorwa nk’umubiri mukuru, hagakurikirahoinzira z'ubuhinzi za kabutike, ibiti by'inzira za rubber, n'inzira za rubber zo gushwanyagurika. Yoherezwa cyane cyane mu Burayi, Amerika ya Ruguru, Ositaraliya, Ubuyapani na Koreya y'Epfo.

Ukurikije umusaruro, Ubushinwa ubu ni bwo bukora ibicuruzwa byinshi ku isiinzira za kabutura, no kohereza ibicuruzwa mu bihugu byinshi ku isi, ariko guhuza ibicuruzwa ni ibintu bikomeye, irushanwa ry'ibiciro rirakomeye, kandi ni ngombwa kongera agaciro k'ibicuruzwa no kwirinda guhangana guhuza ibikoresho. Muri icyo gihe, hamwe n'iterambere ry'imashini z'ubwubatsi, abakiriya bashyira imbere ibisabwa byinshi by'ubuziranenge n'ibipimo bya tekiniki ku mihanda ya rubber, kandi imiterere n'impinduka mu mikorere birimo kugenda birushaho gutandukana. Inganda zikora imihanda ya rubber, cyane cyane amasosiyete yo mu Bushinwa yo mu gihugu, zigomba kunoza ubwiza bw'ibicuruzwa kugira ngo ibicuruzwa byazo birusheho gukurura ku isoko mpuzamahanga.
