Blanking

We are specialists in blanking: The customer expresses a need for a particular part, which is obtained from a flat blank cut from strip different parts of which can then be bent, roll bent and cambered.

A technical and costing study (part geometry and complexity, dimensional tolerances, materials, etc.) is carried out so that we can propose one or more technical solutions, determine a process, then a production operation sheet, and finally present prototypes and initial samples before approval for series production.

Materials

All metals

  • cuprous metals: copper, brass, bronze, nickel silver, beryllium copper, etc.
  • steels: high and low carbon, high-yield, silicon steel (electrical plate), etc.
  • all grades of stainless steel: AISI 301, 304 (L), 316 (L), 430, etc.
  • all grades of aluminium
  • special and custom alloys: tantalum, titanium, special copper alloys (Cuprofor), etc.
  • other (metallic and non-metallic) materials on request, after validation of a representative sample

Parts

  • 1
    Dimensions handled:

    • Thickness: from 0.03 mm to 8.00 mm (depending on the material and geometry of the part)
    • Feed strip width: from 3.00 mm to 500 mm (depending on the material and geometry of the part)

  • 2
    Part forming and assembly process :

    • Blanking, cambering
    • Stamping
    • Drilling, flow drilling, tapping, chamfering, specific machining operations
    • Welding, crimping, clinching, etc.

  • 3
    Subcontracted treatments :

    • Degreasing, tribofinishing
    • Heat treatment
    • Surface treatment (tin plating, zinc coating, silvering, gilding, rhodium plating, etc.) painting, shot peening, etc.
    • Precision fine sheet metal work, bar turning, etc.

  • 4
    Batch size :

    • No minimum production run: we can procure the materials and mount tools to make a single part if necessary
    • Fixed and variable costs are calculated according to the size of the batch required by the customer
    • Maximum batch size depends on the technical characteristics of the part: geometry, dimensions, thickness, material, etc.

  • 5
    Capacities :

    • Maximum production capacity of up to 1,500 strokes per minute over several shifts
    • Maximum batch size of several million parts.

Production – Maintenance

We have all the right equipment to produce and maintain our tools, including EDM machines, surface grinders, lathes and milling machines
