Setup

High capacity and precision production processes

Our contact manufacturing operations are split across several workshops, each with their own expertise, but working together to optimize costs and lead times:

 

  • Screw machining: with automatic swiss cames, as well as cam-driven and digitally-controlled machines such as CNC routers, milling machines, which allows us to maintain a high production rate and to produce complex shapes.

 

  • Secondary-operation machining (Transfer): through which we can apply our expertise in performing complex operations: in particular when working with complex shapes.

 

  • Bending: another area of our expertise, producing simple and complex bent contacts, including bendings in multiple locations, such as the "S-shaped contact". All of these procedures are performed manually or automatically depending on the volume.

 

  • Partial annealing: We have developed a partial annealing process to improve our customization capabilities, working on small-diameter as well as long and fine parts, using flame annealing and induction annealing machines specifically designed for this operation.
  • Plating: We are specialized in galvanoplasty, nickel plating, copper plating, SWISSCOAT, silver, gold, selective gold, and more.

 

  • Assembly: during which we perform assembly of hood and crimping operations, with 100% testing of contact retention forces.

 

  • Colour-coding: allowing us to provide as per standard specs or customize your contacts using colored bands or dots.

 

  • Mechanics & Tooling: through which we oversee the production of our own cams, tooling, etc., allowing us to control costs, lead times, and quality.

 

  • Washing: a crucial operation to clean all parts before any further work or shipping.

 

  • Heat treatments: to increase the hardness or to reduce on the electrical contacts, also to homogenous the material.

 

  • Sand blasting: finalising the cleaning of parts for smooth burr-free products.
     

Innovative production methods adaptable to your needs

As a subcontractor in the connectics sector, we are more than just a manufacturer. Our engineers can support you by co-designing the drawings for your contacts to ensure high-quality products adapted to your needs. Our first class machines (milling machines, CNC routing and machining, etc.) allow us to manufacture orders of any size.

Key facts

Our technology offers several advantages

High-precision screw machines

With more than 50 years of experience and our constant quest for innovation, we are masters of precision screw machining and work with contacts from 0.20 mm to 10 mm in diameter.

Know-how in different materials

We ensure safe production processes are used with different types of materials: copper, copper alloys, brass, bronze, beryllium copper, stainless steels, and thermocouples. Let us know what you need!

High flexibility thanks to a rich machinery

Thanks to supplementary machines with high technological capability, automation and capacity, we are able to set-up various machines, allowing us to produce contacts for any type of connectors, including non-standard sizes.
