Our Infrastructure


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.

Machine Shop

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.

Surface Treatment

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.

  • Phosphating ( Offers better adherence for graphite coating helps in quicker running-in)
  • Graphite coating ( Aids in initial lubrication),
  • Tin plating ( Aids in initial running-in and protection)
  • Hard anodizing ( Protection against thermal cracks)
  • Screen printing with Molybdenum Disulphide.

Quality Assurance

Quality Labs:

In our quest for comprehensive quality, we have deployed a lineup of Quality Labs equipped with an elaborate range of dedicated state of the art testing & measurement equipments calibrated to globally accepted standards. Quality Assurance activities are undertaken by qualified & experienced engineers using documented manuals revised & updated continually. Apart from our metallurgy & metrology labs we have special setup for final Inspection & Visual Inspection of Critical and major characteristics on the product before the same is sent for packaging.

Product Validation : In-house Test Rigs

Product Testing & Validation is done inhouse at our engine test rigs equipped with AVL blow-by meters, & other peripheral equipments with digital output. Test results are co-related using advanced analytical software. We carry out Tailor made / customer specified tests as per agreed / laid down procedure. Various Piston Performance Tests such as Piston Proving Test, Piston Function Test, Piston Scuff Test, Durability Test are done.

Manufacturing Process

Process Engineering

Menon Pistons is committed to continuous Development & upgradation of manufacturing technology & processes using data driven continuous quality improvement system implemented with qualified teams. Our Process Engineering Team consisting of multi-functional teams organized as temporary matrix structures undertakes continuous Process Upgradation & Optimization missions through incremental changes & streamlining of manufacturing operations to improve efficiency by inter alia reducing variations in quality parameters, & eliminating waste & delay in the manufacturing process. Highly reliable data is generated online & offline by using hi-tech measurement equipments. This data is studied & analyzed using sophisticated techniques like DOE, Six Sigma, Motion & Ergonomic analyses to zero in onto & eliminate the possible sources of variations to achieve less variation & reach consistent product quality parameters via mistake proofing. Techniques like Lean manufacturing, Lean Sigma & Kaizen are used to relentlessly identify and eliminate waste & effect continuous improvements through incremental changes & streamlining of operations.
