I-Railway Bogie Bolster Spring Housing iyingxenye yesakhiwo esibalulekile ezinhlelweni zokumiswa kwezimoto zikaloliwe, ezakhelwe ukwakha nokuqondisa umhlangano wasentwasahlobo osekela isisindo somzimba wemoto futhi emunca imithwalo eguqukayo ngesikhathi sokusebenza. Njengengxenye ebaluleke kakhulu ezokuphepha ezinhlelweni zikajantshi wesitimela, i-bolster spring housing kumele imelane nokulayishwa komjikelezo oqhubekayo, ukudlidliza, nezimo zemvelo ezeqisayo kuyilapho igcina ukubekezelela okunembile kobukhulu.
I-Ningbo Ruican ikhiqiza izindlu zentwasahlobo ze-bogie bolster spring zisebenzisa inqubo ye-silica sol yokutshala imali (i-wax casting elahlekile) inqubo, ukufeza amajiyometri angaphakathi ayinkimbinkimbi kanye nokuqedwa okuphezulu okungaba nzima noma okungenakwenzeka ukukukhiqiza ngezindlela ezijwayelekile zokuphonsa isihlabathi noma izindlela zokwenza. Indlu ngayinye ibuye ifakwe ngomshini ngokunemba ezikhungweni zemishini ye-CNC ye-multi-axis ukuze kuqinisekiswe ukujula kwe-bore, ukucaba kwezindawo ezikhuphukayo, kanye nezindawo zembobo ezinentambo zihlangabezana namazinga emboni kaloliwe.
Ineminyaka engu-17+ yokuhlangenwe nakho kokunemba kokusakazwa kanye nokuhlanganiswa kwemishini ye-CNC, i-Ningbo Ruican isebenzela abasabalalisi bezingxenye zikaloliwe, abakhiqizi be-bogie, namadepho okulungisa ujantshi emhlabeni wonke. Uhlelo lwethu lokuphatha ikhwalithi lwe-IATF 16949 luqinisekisa ukulandeleka okugcwele kusukela ekutholeni isitifiketi sempahla eluhlaza ngokuhlolwa kokugcina, ngemibiko enobukhulu kanye nezitifiketi zokuhlola ezibonakalayo ezinikezwa ngakho konke ukuthunyelwa.
