ʻO ka Railway Bogie Bolster Spring Housing he mea koʻikoʻi koʻikoʻi i loko o nā ʻōnaehana hoʻokuʻu kaʻa kaʻa, hana ʻia i ka hale a alakaʻi i ka hui pūnāwai bolster e kākoʻo ana i ke kaumaha o ke kaʻa a hoʻopaʻa i nā ukana ikaika i ka wā o ka hana. Ma ke ʻano he ʻāpana koʻikoʻi palekana i nā noi kaʻaahi, pono ka hale puna bolster e kū i ka hoʻouka ʻana o ka cyclic, vibration, a me nā kūlana kaiapuni ʻoiai e mālama ana i nā hoʻomanawanui dimensional.
Hana ʻo Ningbo Ruican i nā hale punawai bogie bolster me ka hoʻohana ʻana i ka silica sol investment casting (lost wax casting), e loaʻa ana i nā geometries paʻakikī o loko a me ka hoʻopau ʻana o ka ʻili maikaʻi e paʻakikī a hiki ʻole ke hana me ka hoʻolei ʻana i ke one maʻamau a i ʻole nā hana hana. Hoʻopili pololei ʻia kēlā me kēia hale ma nā kikowaena mīkini CNC multi-axis no ka hōʻoia ʻana i ka concentricity o ka pahu, ka palahalaha o nā ʻili e kau ana, a me nā kūlana puka wili e kūpono i nā kūlana ʻoihana kaʻaahi.
Me 17+ mau makahiki o ka ʻike i ka hoʻolei pololei ʻana a me ka hoʻohui ʻana i ka mīkini CNC, lawelawe ʻo Ningbo Ruican i nā mea hoʻolaha mea kaʻaahi, nā mea hana bogie, a me nā hale mālama kaʻaahi ma ka honua holoʻokoʻa. ʻO kā mākou ʻōnaehana hoʻokele maikaʻi IATF 16949 e hōʻoiaʻiʻo i ka traceability piha mai ka hōʻoia ʻana i nā mea maka ma o ka nānā hope ʻana, me nā hōʻike dimensional a me nā palapala hōʻike hōʻike waiwai i hāʻawi ʻia me kēlā me kēia hoʻouna.
