Quality begins at the source. The high quality of casting in our foundry using optimized online process controls ensures that piston blanks with desired alloy compositions & physical properties with optimum micro structures are manufactured.
Our CNC machine line up includes turning centers for machining of re-entrant combustion cavities to ensure high accuracy of profile & machining centers for machining of pin hole relief / oval boring / trumpet boring (for enhancing fatigue life). We have deployed special machining facilities such as Camless CNC Oval Turning in order to achieve piston profile with desired tolerance & to machine symmetrical as well as asymmetrical profiles.
Pistons with surface treatments & coatings, reduce friction & thereby improve fuel efficiency of environmentally friendly engines. Reduced scuffing makes cold engine start up more reliable and quicker. A skirt coated piston has better piston to cylinder 'SEAL' reducing the amount of combustion gases that can escape past the piston & leak into the crankcase. Thus, skirt coating reduces the amount of hydrocarbon emission that would normally pass into the environment as Air Pollutant.
Our setup covers all the four types of surface treatment viz. 1.) Phosphating ( Offers better adherence for graphite coating helps in quicker running-in )
2.) Graphite coating ( Aids in initial lubrication ),
3.) Tin plating ( Aids in initial running-in and protection )
4.) Hard anodizing ( Protection against thermal cracks )
5.) Screen printing with Molybdenum Disulphide.
