About US

        Dongguanshi zhangli machine fittings co.,ltd. is a thermal spraying factory located in the beautiful Humen town Dongguan city China,established in 1998,specializing in the production and repairing of the machinery part with thermal spraying coating in wire & cable,textile & chemical fiber,metallurgy industries,printing and packaging,canned food industry. 
        We have the state of the art spraying equipment : the detonation spray coating series, HOVF spraying series,the wire flame spraying series,the rods and bars flame spraying series and so on.they mainly apply in regeneration of the professional mechanical fitting function,improve the wear-resistance,anti-corrosive,erosion resistance,high temperature proof and conductor adiabatic etc.The mental materials for the spray coating mainly are : chromium oxide ceramics,aluminum oxide,titanium oxide,tungsten carbide,nickel base,cobalt base and so on.we use different material and powder according toclients requirements. 
        In order to provide more satisfactory service to customers and also to improve the quality of products,we've cooperated R&D with colleges and universities positively,for the newest and highest technician of spraying and coating.Furthermore,we have brought in the new coating technician of sintering of Tungsten carbide and Nickel powder on the surface of base material from Germany in 2014,which weed out the traditional hand operation fire flame spraying,and obtained the technician of better rigid and stable coating.
        Aim to improve the products precision,and provide better service to customer,we have equipped with digital controlled lathe center,internal and external grinding machine,milling,drilling,dynamic balance equipment.We have passed the ISO9001:2008 quality management system certification so that we can devote ourselves to offering more superior products and service.
        The surface coating being with high hardness,smoothness and strong binding of the base material,which is of great importance to the industrial level improving,energy saving and the environment protecting.
        Owing to our years of endeavor and research,now our products are applied in many domestic machinery field,within which the tungsten carbide and the ceramic machinery accessories were exported to more than 30countries,and were very well-received among European and southeast Asia countries.
