Profile machining for thermal automotive

We have been a Tier-2 supplier for 45 years, providing machined components to automotive equipment manufacturers (Tier-1).

Our products are primarily used in safety and regulatory systems, including:

  • Steering columns
  • Anti-theft systems
  • Cooling systems
  • Injection systems
  • Hydraulic systems
  • Braking systems
  • Lighting systems
  • Alternators
  • Clutches
  • Turbochargers
  • EGR valves

We manufacture precision components for thermal vehicles from 4 families of materials: steel, stainless steel, aluminum and copper alloys.

I want to be contacted

Manufacturing of precision components in aluminum

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 machined components out of aluminium profiles for thermal vehicles :

Optical reflector

we have 3 patents for the production of reflectors for lighting systems with a coefficient of reflectance >85% for the diffusion of LED light.

Chassis

Some chassis components, such as cross members or reinforcements, can be made from machined aluminum profiles to reduce the overall weight of the vehicle.

Structural and anti-vibration components

Some structural or reinforcing elements can be made from machined aluminum, such as anti-vibration components and control arms.

Components for braking systems

Machined from high-precision aluminum profiles with a high cleanliness standard for fluid flow.

Cooling systems

Aluminum profiles can be used in the manufacture of radiators or other cooling system components to ensure effective thermal dissipation.

Steering systems

Components related to steering, such as brackets or reinforcements, can be made of aluminum to design lighter systems.

Transmission components

Certain parts of the transmission, such as housings or brackets, can be made from aluminum profiles.

Suspension components

Certain suspension elements such as mounts and shock absorber brackets can be machined from aluminum profiles to reduce the weight of the vehicle.

Manufacturing of precision components in steel and stainless steel

We machine precision steel and stainless steel components for the thermal automotive industry from round bars or drawn profiles in steel and stainless steel to meet the needs of demanding, high-volume markets.

Our production is carried out on 30 rotary transfer machines with automatic bar feeders or on 3 or 5- axesCNC lathes.

    • Steel types : 11SMn37, 16MnCr5, 42CrMo4, C45, etc.
    • Stainless steel types : AISI 303, 304, 316L
    • Mechanical properties are improved through heat treatment: nitriding, quenching and tempering, and passivation for stainless steel.
I'd like to have more details
