Ndi chitukuko chosalekeza cha chuma, moyo wa anthu ukupitilirabe bwino, ndipo zofunika zauzimu ndi zakuthupi zikuchulukirachulukira.Kufuna kumeneku kwadzetsanso chitukuko ndi kutsogola kosalekeza kwa makampani opanga nyumba.Kufuna kwamakampani opanga zida zam'nyumba kukukulirakulira.Makampani a hardware akuwonetsa kusintha kosiyana.Makampani a nkhungu ndi gawo lofunika kwambiri pamakampani opanga zida za Hardware ku China.Zaka khumi ndi ziwiri zazaka zisanu ndi nthawi yovuta kwambiri kuti dziko la China liziyankha moyenera kusintha kwakukulu kwa chitukuko cha kunyumba ndi kunja ndikufulumizitsa kukwaniritsa cholinga chomanga anthu olemera m'njira zonse.Ndi nthawi yovuta kwambiri pakukula bwino kwamakampani opanga nkhungu aku China.Ngakhale kuti pali zambiri zosatsimikizika za chilengedwe, chitukuko cha chuma cha China chikadali mu nthawi ya kukula mofulumira.Ubwino wofananiza wa nkhungu zaku China pamsika wapadziko lonse wa nkhungu ukadalipo.Msika wa nkhungu wapakhomo ukuyembekezeka kupitiliza kukhala ndi chiyembekezo, ndipo makampani opanga nkhungu akuwonetsa zomwe zikuchitika.Kuphatikiza kwa maonekedwe ndi ntchito: Zida zamagetsi zimagawidwa m'magulu awiri: hardware yokongoletsera ndi hardware yogwira ntchito.Ambiri opanga mipando yamagetsi amalekanitsa awiriwa, zida zokongoletsera sizilabadira kukula kwa magwiridwe antchito, ndipo zida zogwirira ntchito zili ndi kafukufuku wosakwanira pakukula kwake kokongoletsa, ndipo pali kusagwirizana pakati paziwirizi.Tengani zida zolowera pakhomo mwachitsanzo.Kwa zaka zambiri, ntchito ndi kapangidwe kake zakhala zikupitilizidwa bwino komanso zangwiro, koma salabadira mgwirizano wa zokongoletsera.Ngakhale kuti mankhwala ambiri ndi othandiza kwambiri, nthawi zonse amawoneka osasangalatsa.M'zaka zaposachedwa, ndikusintha kwa kapangidwe kazinthu zatsopano, opanga ambiri amayang'anitsitsa zida zapanyumba ndikuwunikanso zida za mipando ndi lingaliro la kapangidwe ka mafakitale.Ndi kachitidwe kachitukuko ka zida zam'mipando kuti aphatikize bwino mawonekedwe ndi magwiridwe antchito amipando..Kulondola kwa nkhungu kudzakhala kokwera kwambiri.Zaka khumi zapitazo, kulondola kwa nkhungu zolondola nthawi zambiri kunali ma microns 5, ndipo tsopano zafika pa 2 mpaka 3 microns, ndipo nkhungu zokhala ndi 1 micron zidzagulitsidwa posachedwa.Izi zimafuna kumaliza kwambiri.Bizinesi ya nkhungu idzakhala yayikulu komanso yayikulu.Izi zimachitika chifukwa cha kukula kwa nkhungu imodzi yokhala ndi zibowo zingapo chifukwa cha kukula kwa magawo opangira nkhungu komanso zofunikira zazikulu zopanga.Mipikisano zinchito composite nkhungu mu makampani nkhungu adzapitiriza kukula.Kuphatikiza pa kupondaponda ndi kupanga zigawo, nkhungu yatsopano yamitundu yambiri imagwiranso ntchito pamisonkhano monga lamination, tapping, riveting, and locking.Zofunikira pakugwira ntchito kwachitsulo zikuchulukirachulukira.
