Piston Reconditioning
Precision Laser Cladding Reconditioning of Piston Crown Grooves to Restore OEM Ring Clearance & Operability
Pistons in 4-stroke marine engines are subjected to extreme pressures, high combustion temperatures, and continuous friction, especially in the piston grooves area, where wear is most severe. This often leads to costly pistons replacements and operational downtime.
KIMI provides advanced laser cladding reconditioning as a durable, precision-engineered, and cost-effective alternative, restoring worn pistons to exact OEM dimensions. Our reconditioning solutions are suitable for steel, cast iron, and aluminum pistons, ensuring full compliance with OEM standards across all major 4stroke engine makers, such as MAN 23/30, MAN 32/40, MAN 27/38, Wärtsilä 32/20 and MaK M20/M25/M32.
In addition, our process includes piston skirt coating application using state-of-the-art technology to enhance lubrication, reduce friction, and extend overall piston and engine life.
