We are an exclusive manufacture producing Continuous Cast Iron Hollow Bar which is..
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 (cylinder liner,bushing,pulley,piston ring...)
Machined parts in these and other industries are already benefiting from us material advantages:
Fluid Power --Oil & Gas-Industrial-Defense--Primary Metals--Automotive Aftermarket
Shaanxi Tongxin Continuous Cast Tube Tech Co., Ltd. is established in August, 2006 and located in west suburb of xi'an city, shaanxi province in China, which is a corporate enterprise co-invested by xi'an university of technology and a private enterprise. Based on horizontal continuous casting for "profiles of cast iron"(solid), we innovated "physics force field confinement and shaping continuous casting technology" independently in 2006, using this technology we manufactured a new product---hollow profiles of cast iron. Our products have been tested by China's authority sector in mechanical industry and proved that the quality is much better than traditional sand-casting and centrifugal casting products. Our products can meet the requirement of high density, zero deficiency and easy cutting". It is also the only product with following appearance characters in China's market of casting products: Thin diameter, thin wall pipe and near net shape. It has been widely used in China's mechanical industries, such as railway vehicle, oil machine, engineering machine, accessories of auto engine, compressor, hydraulic pressure, chemical pump, machine tool, metallurgical equipment and etc. Meantime, some samples are on trial in United States, Korea, Syria, and Denmark.
