FROM DESIGN TO MACHINING
The specification guides the process.
01
The manufacturing route
Forged-blank machining and billet machining follow different preparation routes. Material grade and the route are confirmed for each project.

Internal geometry and machining
Pockets, webs and pin-boss transitions are visible in the supplied product photographs. The design and machining approach are reviewed together.

Precision tolerances. ±1 g matching.
Drawing-based dimensional inspection and weight matching within ±1 g for specified matched sets support consistency from part to part.
Explore this detail ↗MATERIALS & ENGINEERING
Strength starts with the material.
2618 forged aluminium
A dense forged structure designed for higher combustion pressures, temperatures and engine speeds. Selected products use 4032 or 2618 aluminium, with the alloy chosen for the application.
FEA-informed development
Selected designs use finite element analysis to optimise stress distribution. Forging supports thinner-wall, weight-conscious designs while retaining the strength required by the application.
A controlled manufacturing route
From raw-material forging to CNC finishing, process control and inspection focus on ring-groove quality, dimensional tolerances and consistency.
Materials for demanding projects
Specialist projects can specify high-strength aluminium, steel or titanium-alloy solutions for the relevant piston or component. Material and component scope are defined for the application.
SURFACE & FRICTION CONTROL
Engineered beyond the metal.
Molybdenum skirt coating
Molybdenum skirt coatings help reduce friction and improve running-in. Selected skirt-coating configurations also help control operating noise.
Application-specific treatments
A range of surface treatments supports service life and reliability. The finish is selected with the material, running clearance and operating conditions.
PRECISION & VALIDATION
Consistency, part after part.
Weight matching within ±1 g
Piston weight matching is controlled within ±1 g for specified matched sets. Precision tolerances and dimensional consistency are part of the agreed inspection requirements.
OEM experience. Racing development.
JND brings OEM experience and OEM-level validation practices into performance piston development, supported by extensive R&D and motorsport resources.
