A high quality alternative to castings due to:
No porosity, slag, shrinkage or other typical casting defects
Dense, fine-grained microstructure
Thin wall tube Min. 7mm only
No pattern or tooling costs
An excellent cost-saving alternative to low-medium carbon steel because of:
Better machinability - up to 3 times faster with better chip control (no more long, tangled, sharp chips)
Minimized deburring
Longer tool life
Improved wear resistance
10% lighter weight
Quieter due to vibration damping
30-70% material saving compare with solid bar for hollow parts
Machined parts in these and other industries are already benefiting from our products:

I. Intro:
Based on horizontal continuous casting for cast iron profile(dense bar), we've developed new casting tech Vertical upward 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 advantages including high density, zero deficiency, close final shape(tube), superb wear resistance, high purity, excellent machinability and fatigue strength etc.
II. Material:
We could supply the continuous cast iron profile as follow:
1. Ductile Cast Iron Pipe/bar(ISO: 400-8/500-7/600-3/700-2/800-1)
---spheroidization rate 90%, ball diameter 7~8, ball number 400~600/mm2
---compare sand casting, at same strength, elongation increase 50~100%
2. ADI(Austempered Ductile Iron)
---b1200PA, 2%, ak35J/mm2
3. Gray Cast Iron Pipe/bar(ISO: 150/200/250/300/350)
---Matrix: Ferrite pearlite
---b=150-380 MPa, HB=150-240, E=1.1-1.7*105MPa
4. Alloy Gray Cast Iron Pipe/bar
--CrNiMo Cast Iron--CrMoCu Cast Iron--High Nb Cast Iron--VNb Cast Iron
--High B Cast Iron--High P Cast Iron--High Ni Cast Iron...
III. Specification:
---Cross-Section: Round, Rectangle, Elliptic, Hexagonal
---OD: 60-320mm, Thickness: 8-35mm
Our products could be widely used in mechanical industries, such as railway vehicle, oil machine, engineering machine, auto parts, compressor, hydraulic and pneumatics, 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.
