High Density,Zero Deficiency,CloseTo Final Shape(tube),Corrosion Resistance,Fatigue Strength,Excellent Machinability,High Purity

 Based on horizontal continuous casting for cast iron profile(dense bar),we've developed new casting tech ‘physics force field confinement and shaping continuous casting’ in 2006, by using this tech we manufactured new kind of cast iron profiles ---Cast Iron Hollow Bar , which have been tested by chinese authority sector in mechanical industry and proved that the quality is much better than traditional sand-casting or centrifugal casting profiles .Our profiles have many advantages such as high density,zero deficiency,close final shape(tube),wear resistance,high purity,excellent machinability and fatigue strength etc. It has been widely used in mechanical industries,such as railway vehicle, oil machine,engineering machine,auto parts,compressor, hydraulic pressure,chemical pump, machine tool,metallurgical equipment etc.Meantime, we also supply related products in blank, such as cylinder liner,piston ring,ADI bushing,sealing ring,suction pipe etc. By using our profile, the working life of our products will be 5 times than sand casting,and no pore,sonim... Adapt to strict requirments in precise manufacturing,such as F1 racing car,air engine,petroleum facilities etc.
