Piston Manufacturers & Suppliers in India

Piston is a very important component of an engine. Piston manufacturers fabricate Grindlays Pistons from high quality aluminum alloys which cater to International standards and are known for their best performance, reduced friction and non-expansion in the engines. As per Piston suppliers, it is very important that piston is made of good quality material because it is a disc or short cylinder fitting closely within a tube in which it has to move up and down against a liquid or gas, used in an internal-combustion engine to extract motion, or in a pump to impart motion. Only properly manufactured pistons can assure the right transfer of force from and expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. In case of a pump, this function is reversed and the force is transferred from the crankshaft to the piston to compress or eject the fluid in the cylinder. In some cases, the piston also acts as a valve by covering and uncovering ports in the cylinder wall.

Quality Commitment

Accuracy is maintained “in all fronts”  Weight, Dimentions, Raw Materials. All the pistons are heat treated to provide best efficiency and non expansion at elevated temperatures. All the pistons produced are subjected to various inspection tests such as - Weight, Dimentional check(Diameter, Height, Cam, Ovality, Pin Bore, Stroke / Compression Ratio, Cavity Volume etc.), Hardness, Porosity.
