RBSIC and SSIC
zhejiang dongxin seals co.,ltd was established in 1986,its main products are silicon carbide(reaction bonded silicon carbidel/RBSIC and presssure sintering slicon carbide/SSIC and sintering slicon carbide+ carbon/SSIC+C),carbon graphite,and hot-pressed graphite and tungsten carbide and seried products.
we can make the big size SIC rings(OD more than 680mm).
our company is high and new Tech Enterprise in Zhejiang Province.it is one of the 500 Most Growth Small and Medium size Enterprise in China.it is the butt enterprise with National 863 plan,and it is the leading company who develop and reserach Nanotech Ceramic seals in its industry.
our company passed ISO9001:2000 Quality Management System Certificate in 2002,we are the long term supplier of EagleBurgmann company (Germany) for silicon carbide rings and carbon rings and tungsten carbide rings.
Our market have extended from domestic to oversea,which are included Asia,Europe,and USA and so on,we have already built steady relationship with more than 400 clients.
