Nkuko inganda zitwara ibinyabiziga zirimo igihe cyiterambere ryihuta, ubuziranenge bwo hejuru, imikorere myiza hamwe nigiciro gito cyibicuruzwa bigenda bisabwa byingenzi mumarushanwa yisoko.

Kubisabwa kugirango habeho gutunganya no gutunganya ibice byimodoka, C&W yateje imbere ibikoresho byabigenewe hamwe nibikoresho bifasha ibisubizo, hamwe nuruhererekane rwibintu bishya byagezweho, bitanga ibisubizo byumwuga byo gutunganya moteri ya moteri ya moteri, umutwe wa silinderi, guhuza inkoni, kamashaft, crankshaft na sisitemu yohereza, sisitemu yo gufata feri, axe nibindi bice byimodoka.

Ukurikije ibiranga inganda zo mu kirere, indege irashobora kugabanywamo ibyiciro bibiri:

kimwe ni ukumenyera gutunganya aluminium, magnesium alloy nibindi byuma, bikarangwa no kuvanaho ibyuma binini, gutunganya umuvuduko mwinshi, ikindi nukumenyera gutunganya itunganywa rya titanium, nikel ishingiye ku mavuta, ibyuma bitagira umwanda nibindi bikoresho bikomeye byo gutunganya, ibikoresho byo gukata kugirango bikore neza kandi bikore neza, bihuze no gukata gukomeye. C&W irashobora gutanga igisubizo cyiza kubice bya moteri yinganda zo mu kirere.

Imashini zubaka zirimo ibicuruzwa biva mu mahanga, imizigo, crane, ibizunguruka mu muhanda, amakamyo ya pompe, imashini ikingira, n'ibindi.

Ibigize bigizwe ahanini nuruzitiro rukomeye-rukomeye rwicyuma, ibyuma bidashobora kwangirika, ibyuma bya manganese ndende, ibyuma byangirika, hamwe nudusimba twinshi. Berekana amafaranga menshi yo gutunganya, imitwaro iremereye, hamwe nibikoresho bikomeye. Kwinjiza karbide ya sima, hamwe nibyiza byo gukomera kwinshi, kwihanganira kwambara cyane, kurwanya ingaruka, no kwihanganira ubushyuhe bwinshi, byahindutse ibikoresho byingenzi byo gutunganya.
