Reconditioning is usually the most cost-effective solution for dealing with piston crown damages. However, reconditioning process can differ a lot from vendor to vendor. Some of the most critical factors that define the quality of the reconditioning service are:

  • The restoration of the piston crown back to the original dimensions. Building up and not just machining is required in order this factor to be satisfactory
  • Grooves chrome plating thickness
  • Grinding of piston ring grooves after machining
  • Quality assurance throughout the repair process and quality control
  • Traceability of the reconditioned component

KIMI offers an end-to-end automated and seamless rebuilding procedure for piston crowns that involves 3-D scanning evaluation, multiple AI Powered welding robots, and latest technology CNC machines. This way we ensure fine-tuned welding parameters, proper penetration, consistent & high quality welds every single time, free of thermal stresses. Also, it is a material adaptive rebuilding process providing the capability to adjust according to material type, considering inherent base material flaws.

As a standard procedure piston ring grooves are completely removed and re-built from scratch.

KIMI’s cutting edge In-house chrome plating infrastructure guarantees both full compliance with maker’s specifications and increased durability.

Grooves are grinded on each side and maximum grinding parallelism deviation is 0.01mm while the chrome plating thickness is 0.50mm on each piston groove side

We, at KIMI, based on the above, offer a full-rebuilding, premium quality service that includes:

  • Full warranty of 20.000 running hours is offered for piston crown rebuilding
  • Improved performance, quality equal to new
  • Cost effective service beyond compare through our cutting-edge AI Robotic systems
  • Reduced downtime through 24/7/365 AI robotic operation
  • Stringent quality control protocols and checks by PCN Level II certified initial and final inspection, if necessary even in between the repair stages, in order to increase customers’ visibility
  • Enhanced traceability with KIMI logo and order number stamp on pistons for easy tracking
  • The option of applying Inconel on piston’s top surface for higher corrosion resistance
  • Piston crowns (available in stock) for providing on exchange basis or for sale
