Material Tech-Focus on centrifugal casting

• 10 series of 25 kinds of materials，include matrix structures of bainite, pearlite, austenite，martensite，ferrolites
• Mature  nodular cast iron and Compacted graphite iron castings Production process
• Tin bronze, aluminum brass and other copper alloy materials
• Chromium Alloy Anti-wear iron

Honing Tech-High Quality and clear

• Plateau honing, spiral sliding honing, laser honing, brush honing, lapping honing

Surface Treatment-Different conditions, a variety of choices

• Phosphating, ion nitriding, gas nitriding, salt bath nitriding, isothermal quenching, vacuum hardening，high frequency hardening, tempering, normalizing, annealing, etc. 
• Effectively improve the capacity of anti-cavitation and anti corrosion, and reduce the frictional work

Strengthening 

• Shot peening and rolling can increase the cylinder liner minimum breaking load,improving the ability of anti fatigue-fracture
