Urban Mobility

We manufacture components for urban mobility machined from profiled or round bars in steel, aluminum and copper alloys.

Our technical department determines the optimal manufacturing process by developing clamping and machining systems to ensure product quality (calculating deformations during machining, anticipating distortions after heat treatment, etc.).

Our technical resources and our patents for high-precision surface finishing of aluminum enable the production of machined components on:

  • 10 5-axis CNC lathes
  • 7 4-axis CNC machining centers
  • – 30 rotary transfer machines

We implement various manufacturing processes for the production of strategic components for urban mobility:

  • Machining from +QT raw materials
  • Nitriding
  • Gear cutting class 6
  • Grinding
  • 100% camera inspection


We manufacture precision components using extruded aluminum profiles. This material offers weight savings (increased energy efficiency), mechanical strength (through T4 or T6 heat treatment), durability, and recyclability.

The aluminum we use can be made up of 75% recycled material, reducing its carbon footprint.

Our production is carried out on rotary transfer machines with automatic aluminum profile loading, or on robotized machining centers.

  • Aluminum alloys : EN AW 2017, 5083, 6060, 6061, 6082
  • Heat treatment to improve mechanical properties: quenching – aging for T4 or T6 state, stabilization.
  • Surface treatment: anodizing, metallization to improve the reflectance coefficient.
Applications of components out of aluminium profiles :
  • Battery cases
  • Motor support
  • Handles and Pedals

High performance metals

Our precision-machined components, made from steel, stainless steel, titane, and nickel alloys, are primarily used for automatic gearboxes such as shafts and transmission components.

  • Steel grades : 11SMn37, 16MnCr5, 42CrMo4, C45
  • Stainless steel grades : AISI 303, 304, 316L
  • Titanium, WASPALOY
  • Mechanical properties are improved through heat treatment: nitriding, quenching and tempering, and passivation for stainless steel.

We manufacture strategic components for automatic gearboxes for electric bikes

Manufacture of the primary shaft out of 42CrMoS4 +QT with gear cutting class 6, heat treatment, grinding and 100% inspection with camera system

We combine additional operations with machining to improve the quality of our products.

Triboloby operations for deburring and polishing

We perform in-house finishing by shot peening or mass finishing for deburring, polishing, and improving surface criteria (roughness and bearing capacity).

Multi-tank, ultrasonic, detergent washing machine

The cleanliness requirements of our products are guaranteed by a multi-tank, ultrasonic, detergent washing line and a robotized, modified alcohol washing line.

Robotized, modified alcohol washing line

The cleanliness requirements of our products are guaranteed by a robotized, modified alcohol washing line.

Robotic cell for traceability through laser marking

Unit traceability is carried out using automatic laser marking machines such as QR CODE or DATAMATRIX.

Geometric compliance is ensured by three-dimensional measuring machines (CMMs) and 6 automatic inspection machines with camera, eddy current, and scanning capabilities to detect various types of damages (surface defects, tearing, cracking).

Quality control

To meet the quality requirements of our customers, we have a metrology laboratory for dimensional measurements equipped with 3 continuous contact CMMs, optical fiber reflectance measurement, and optical surface defect inspection. To ensure 100% compliance of our products, we have a fleet of 7 automatic inspection machines equipped with eddy current, vision for dimensional inspection, and scanning for surface quality. We are certified ISO 9001, TS16949 and IATF.
