Nga ekintu ekikulu eky’obuyambi mu mulimu gw’okusaanuusa n’okusuula ebyuma, obwetaavu n’omutindo gwa carburizer byeyongedde nnyo mu myaka egiyise nga okulongoosa amakolero g’amakolero aga waggulu-End manufacturing industry. Nga ekirungo ekigatta ekiyinza okwongera obulungi ku kaboni ali mu kyuma ekisaanuuse, omutindo gwa carburizer gukosa butereevu eby’obutonde eby’ebyuma, obugumu n’okuziyiza okwambala kw’ekintu ekisembayo, kale kifuuse ekintu ekikulu ekitasobola kubuusibwa maaso mu kifo ky’ebyuma.
Mu ngeri y’ebintu, ebirungo ebizimba omubiri (carburizers) bisinga kugabanyizibwamu graphite carburizers, petroleum coke carburizers ne coal-ebikozesa carburizers ebisinziira ku. Mu byo, graphite carburizers zikozesebwa nnyo mu kukola high-end castings n’ebyuma eby’enjawulo olw’obulongoofu bwabyo obw’amaanyi, sulfur entono n’engeri entono ey’okukuuma obutonde bw’ensi. Petroleum Coke Carburizers zitwala akatale wakati -enkomerero n’ebirungi by’omuwendo omutono n’okugabira okutebenkedde, ate amanda-okusinziira ku carburizers gasuulibwa ku bbali mpolampola akatale olw’obucaafu bwabyo obw’amaanyi. Enjawulo mu kigero ky’okunyiga, okuddamu okukola n’okukuuma obutonde bw’ensi mu bikozesebwa eby’enjawulo eby’ebintu eby’enjawulo bizifuula ezisaanira ebyetaago eby’enjawulo eby’enkola y’okusaanuusa.
Ku nsonga z’ebyetaago by’okukuuma obutonde bw’ensi mu nsi yonna okweyongera, ekibiriiti ekitono, nayitrojeni omutono n’obulongoofu obw’amaanyi (high purity carburizers) bifuuse oludda olukulu mu kukulaakulanya amakolero. Abakola ebintu bangi bongera okulongoosa enkola y’okunyweza ebbugumu n’okunyiga kaboni mu bikozesebwa mu kuzzaamu amaanyi nga balongoosa enkola y’okuyooyoota n’okwongerako ebiziyiza. Mu kiseera kye kimu, okumanyisa enkola z’okukuba bbomu mu ngeri ey’obwengula (automated batching systems) nakyo kifudde okukozesa eddagala erikola ebirungo ebizimba omubiri (recarburizers) okutuufu, okukendeeza obulungi ku kasasiro n’obucaafu mu nkola y’okusaanuusa.
Okusinziira ku ndowooza y’akatale k’okutunda ebweru w’eggwanga, obwetaavu bw’ebikozesebwa mu kulongoosa ebirungo ebizimba omubiri ebya waggulu-eby’omutindo mu makolero g’ebyuma n’ebyuma ebikozesebwa mu kukola ebyuma mu Southeast Asia, Middle East ne Bulaaya byeyongera okukula. Nga amakolero ga China ag’amakolero gakyuka ne gafuuka omuwendo omunene-ebitundu eby’ongerako, ensengeka y’okutunda ebweru w’eggwanga eya recarburizers nayo egenda ekyuka mpolampola okuva ku low-enkomerero y’ebintu okudda ku 3}}End customization. Mu biseera eby’omu maaso, abagaba eddagala eriweweeza ku bulwadde buno abasobola okuwa omutindo omutebenkevu, okugoberera obutonde bw’ensi n’okutuukiriza ebyetaago eby’enjawulo bajja kusinga kwagala katale k’ensi yonna.
Okulongoosa mu tekinologiya n’enkyukakyuka mu bwetaavu bw’akatale mu mulimu gwa Recarburizer biraga omulimu gw’okukola ebintu mu nsi yonna ogw’okukola ebintu eby’amaanyi n’enkulaakulana ey’olubeerera. Mu biseera eby’omu maaso, olw’okutumbula enkola empya n’ebintu ebipya, abaddamu okukola ebirungo ebiddamu okukola ebirungo ebizimba omubiri (recarburizers) bajja kukola omulimu ogutayinza kukyusibwa mu bintu ebisingawo.
