In-House Chrome Plating for Marine Piston Crown Reconditioning

0.50 mm per groove side. Complete process control. Entirely at KIMI.

Chrome plating of piston ring grooves is a critical stage in the reconditioning of two-stroke piston crowns. Keeping this process in-house gives KIMI direct control over surface preparation, plating parameters, final thickness verification and quality inspection, while reducing dependence on external subcontractors. KIMI invested in a dedicated in-house chrome plating facility to integrate this stage into its piston crown reconditioning workflow. This enables closer coordination between restoration, machining and plating, with full process traceability and greater control over repair schedules.this means fewer external handovers, coordinated quality checks and better control over the complete reconditioning schedule.

No outsourced plating

In-house chrome plating removes the need to fit this critical stage into an external subcontractor’s schedule.

Fewer component transfers

Piston crowns remain at KIMI for welding, machining and plating, reducing transport and external handling.

Controlled plating quality

Surface preparation, plating parameters and final thickness are controlled and verified within KIMI’s facilities.

Full process traceability

Process records and inspection results document the work performed throughout piston crown reconditioning.

Controlled plating thickness. Documented verification.

For piston crowns, KIMI applies a controlled chrome plating thickness of 0.50 mm per groove side, in accordance with the applicable Maker’s requirements.

Control extends beyond the plating operation itself. Surface preparation, process parameters and final thickness verification are managed within KIMI’s facilities, keeping responsibility for execution and inspection with the same engineering partner.

Integrated with welding, machining and inspection

Chrome plating forms part of KIMI’s complete piston crown reconditioning capability, alongside AI-controlled robotic welding, CNC machining and staged inspection.

Managing these processes under one roof allows each stage to be coordinated with the next. Welding restoration and machining are connected directly with plating and quality inspection, reducing external handovers throughout the repair workflow.

This integrated approach supports shorter repair lead times while maintaining consistent reconditioning quality. KIMI’s complete piston crown reconditioning service is backed by a 20,000 operating hours guarantee.
