Metal fabrication

CNC punching

CNC punching is our core in-house process. Numerically controlled turret punching machines hold accuracy and repeatability across production runs. They cover punching, stamping and nibbling of flat sheet metal.

• Max sheet size: 3000 x 1500 mm. Thickness: 3 mm for standard sheet, 5 mm for pre-coated sheet
• Shaped hole punching
• Extruded holes for M2.5 to M6 threads
• PEM fastener insertion

On thin sheet, these machines also let us:

• Shorten set-up times between runs and keep short-run work flexible
• Produce many different cut-outs from a single sheet clamping
• Draw zinc over the cut edges when processing pre-coated sheet

Sheet metal cutting

We cut on guillotine shears and a sheet metal shear.

Pressing

Pressing parameters:

• Eccentric presses: 6 - 160 tonnes
• Hydraulic and mechanical presses: 6.3 - 250 tonnes

Bending

We use numerically controlled press brakes from established manufacturers. This gives us:

• High accuracy
• Repeatable bends
• A constant angle along the full bend length

We bend, cut and perforate sheet metal, and turn, drill and mill steel, stainless steel and aluminium.

Bending of profiles, tubes and sheet on CNC AMADA press brakes.

Welding

We weld a wide range of materials by several methods. Years of experience in material selection go into the strength, durability and appearance of the welds.

Steel and aluminium welding:

• Semi-automatic, CO2-shielded machines using wire of 0.8, 1.2 and 1.6 mm diameter
• TIG AC/DC: 400 A
• MIG/MAG: 500 A

Resistance (spot) welding of sheet 0.5 - 4 mm thick:

• Stud and bush welding
• Resistance welding of sheet components, including projection welding of rivets, nuts and grounding terminals

Laser cutting

We cut sheet metal and aluminium to an accuracy of 0.05 mm, with a max sheet size of 3225 x 1535 mm.

Powder coating

We powder coat steel and aluminium on our own automatic in-house lines. Work is carried out to EU health, safety and environmental standards.

  • 550 x 1550 x 6000 mm
  • 800 x 1700 x 6000 mm
  • 1750 x 1750 x 7000 mm
• Polyester powders to the RAL palette
• Gloss grades: 80, 70 and 30 (±5)
• Smooth or textured finishes, from gloss through semi-matt to matt
• All powders free of heavy metals
• Compliant with ISO 9001 and RoHS (Directive 2002/95/EC of 27 January 2003)

Aluminium anodizing

Matt (satin) anodizing on an automatic rack line, profile size 500 x 1700 x 6200 mm. Profiles for building facades and interior design.

Minimum load (jig) of 50 m². Allow up to 50 mm at each end for mounting in the jig.

Anodizing on stationary equipment for smaller parts, for example furniture finishes, stands and shower-enclosure parts. Profiles up to 3500 mm in length.
