Ububanzi obuthile obutholakalayo bungenziwa ngokwezidingo zekhasimende.

Yebo, i-201 stainless steel narrow coil ingashiswa kusetshenziswa izindlela ezijwayelekile zokushisela, okuhlanganisa i-TIG, i-MIG, nokushisela amachashaza, uma nje kulandelwa izinqubo ezifanele. Ukuba nikel okuphansi kwayo kusho ukuthi imingcele yokushisela ingadinga ukulungiswa kancane uma iqhathaniswa ne-304, kodwa into leyo inikeza ikhono elihle lokushisela ezinhlelweni eziningi zokuhweba. Ukukhetha into efanele yokugcwalisa nokulawula ukufudumala okungenayo kuqinisekisa ukuthi amalunga okushisela aqinile.

Kunezindlela eziningi zokuqeda ezitholakalayo, kufaka phakathi i-2B finish evamile, i-No. 4 brushed finish, ne-mirror finish, kanye nezinketho ezikhethekile ezifana ne-PVD colour coating, i-embossing, ne-etching. Ukukhethwa kwe-finish kuncike ezidingweni zobuhle nokusebenza okudingekayo kusetshenziswa lokho ekugcineni. Abakhiqizi abaningi banikela nge-finish engenziwa ngokwezifiso ukuze bahlangabezane nezidingo ezikhethekile zamakhasimende.

I-201 steel grade stainless steel narrow coil isetshenziswa kakhulu ekwakheni nasekuhlobiseni, ezingxenyeni zezimoto, ezitsheni zokupheka nasezintweni zikagesi, nasemishinini yezimboni. Ithandwa ngenxa yokungabizi kakhulu, amandla ayo aphezulu, nokumelana nokugqwala okuhle ezindaweni ezingenamandla okulimaza. Ukusebenza kwayo ngezindlela eziningi kuyenza ibe into esemqoka emikhiqizweni eminingi ebunjiwe, ebunjiwe, neshiselwe.

Nakuba insimbi engu-201 ingasetshenziswa ngaphandle ezindaweni ezinemozulu epholile, ayinikezi izinga elifanayo lokumelana nokugqwala njengezinga elingu-304 noma elingu-316. Ezindaweni ezisogwini noma ezingcolile kakhulu, ingase ithinteke ekuboleni nasekubalekeni kombala. Ngakho-ke, ezicelweni ezibalulekile zokwakha zangaphandle, kubalulekile ukuhlola ngokucophelela izimo zemvelo futhi kungenzeka ukhethe izinga eliphezulu.

Ububanzi bunqunywa ukuhlelwa kwemimese yokudwengula ejikelezayo, ebekwa kububanzi obunqunyiwe kusetshenziswa izihlukanisi ezinembile ku-arbor. Lokhu kuhlela kuvumela imicu eminingi yobubanzi obufanayo noma obuhlukile ukuthi ikhiqizwe ekudluleni okukodwa. Inqubo iqinisekisa ukubekezelela kobubanzi obunembile kakhulu, ngokuvamile phakathi kuka-±0.1 mm.

Yebo, abakhiqizi abahloniphekile banikeza ububanzi bokusika ngokwezifiso kanye nezinhlobonhlobo zokuqedwa kwendawo ukuze kuhlangatshezwane nezidingo ezithile zomkhiqizo. Abathengi ngokuvamile banikeza umthengisi ukubekezelela ububanzi abakudingayo, ukumbozwa, nokuqedwa, okwenza umthengisi akwazi ukulungisa ulayini wabo wokukhiqiza ngokunjalo. Leli khono lokwenza ngokwezifiso libalulekile kubakhiqizi abanezinqubo eziyingqayizivele zokugxiviza noma zokubumba.

Amakhoyili kufanele agcinwe endaweni eyomile, enomoya omuhle ngaphakathi, ngokufanelekile emashalofini avimbela ukuthintana okuqondile nomphansi kanye nokungena komswakama. Kubalulekile ukugwema ukugcina impahla eduze kwamakhemikhali noma ezindaweni ezinomswakama ophezulu ukuze kuvinjelwe ukungcoliswa kwendawo. Ukuphatha ngendlela efanele ngemishini yokuphakamisa efanele nakho kubalulekile ukuze kuvinjelwe ukulimala kwemiphetho kanye nokuguquka kwekhoyili.

Bheka abahlinzeki abagcina izitifiketi zokuphatha ikhwalithi ezifana ne-ISO 9001, futhi abakwazi ukunikeza izitifiketi zokuhlola izinto ezikuqinisekisa ukwakheka kwamakhemikhali nezimfanelo zemishini. Ukuqinisekiswa ezindinganisweni ezifana ne-ASTM A240 noma i-JIS G4305 kuqinisekisa ukuthi into ihlangabezana nezindinganiso zamazwe ngamazwe ezaziwayo. Umhlinzeki ohloniphekile njenge-Guangdong Shiji Feiyang uzobe esobala mayelana nokulawula ikhwalithi yakhe nezinqubo zokuhlola.
