Our 45 years of expertise in machining steel, aluminum, and copper alloy profiles enables us to produce precision components for various industries.

  • Security : locking bolts
  • Watchmaking : links for watch straps
  • Agriculture : hydraulic components
  • Electrical : copper alloy connectors
  • Building : aluminum fixing and connecting components for verandas, guardrails, solar panels and carpentry.

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 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

Our precision components are primarily used for applications in housing, such as verandas, guardrails, and fixing and connecting parts for aluminum carpentry and solar panels.

Steel and stainless steel

We machine precision components from round or profiled bars made of steel and stainless steel to meet 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.

Our precision components are mainly used for watchmaking (watch straps), high pressure hydraulics and industrial equipment applications.

We are specialized for over 30 years in the manufacturing of locking bolts for locksmithing (over 100,000,000 pieces produced) for locking and security systems.


We manufacture precision components from copper alloys that promote electrical conductivity. These components are used for low and high voltage connections on vehicles.
  • Material types (copper or brass) : Cu, C11000 H04, TeCu, C14500
  • Surface treatments to improve conductivity such as silver plating
Applications of copper alloy profiles:
  • Electrical Cable Connectors
  • Connection Terminals
  • Battery Connectors
  • Solar Panel Connectors
  • Industrial Machine Connectors
  • Lighting System Connect
  • Electric Heating Connectors
  • Communication System Connectors

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.
