Composite panel

Working with Composite panels

No lubricant is necessary. Ensure that all chips or splinters are removed after each processing step in order to avoid scratches. While working with composite panels, the protective film must remain on the tiles. It is recommended to only work with composite panels at room temperature.

1. Cutting

Sawing

The usual sawing methods for aluminium can be used, e.g. panel saw, circular hand saw, jigsaw, band saw.

Circular sawing

  • Cutting blade with planar or trapezoidal teeth
  • Cutting speed: from 3 to 5,000 rpm
  • Feed: 30 m/min.

Cutting

Composite panel tiles can easily be cut using aluminium guillotine shears. When cutting, pull the cover sheet gently downwards at the edge so that the visible side is facing downwards.

2. Punching

Follow the same instructions as for cutting. The blade clearance must be no wider than 0.10 to 0.15 mm.

3. Drilling

  • With standard metal drills: high-speed or carbide drill
  • Cutting speed: from 30 to 300 rpm
  • Feed: max. 0.5 mm/revolution

4. Milling

CNC milling, portable router and all other standard aluminium milling processes can be used:

  • Cutting speed: 3 to 5,000 m/min
  • Feed: 30 m/min

5. Manual bending

Composite panels can be bent easily by hand if you mill out V-shaped grooves on the back of the sheet. When milling, we recommend stopping at 0.5 mm from the plastic core. To bend the material properly, the milled groove should have a flat area of 2 to 3 mm.

6. Bending

Minimum bend radius: R mini* = 15 x thickness (* depending on the system) Look out for the rebound effect, which usually occurs when bending sheets. Composite panels can be bent on a folding machine, press brake and roll bending machine.

7. Bonding technique

Rivets

Composite panels tiles can be bonded with each other or other materials using the standard rivet types for aluminium.

Screws

Wooden, self-tapping or metal screws may be used, depending on the substructure. Use the largest possible screw heads and washers to ensure that the surface pressure is not too high.

Adhesive bonding - hot air welding

Tiles can be bonded with the standard metal adhesives or with adhesive tape on both sides. Try to avoid simply sticking tiles together end-to end. In such cases, use the hot air welding process and PE wire.

8. Surface processing

Spray painting
(reverse)

Air-drying acrylic or two-component polyurethane paints are highly suitable for spray painting. Oven drying up to max. 80°C will speed up the drying process.

Adhesive bonding

A good bond can only be achieved if surfaces are free of grease and dirt.

9. Storage

The tiles must be stored at room temperature when dry, in a place not directly exposed to sunlight. After removing a few tiles from their original packaging, they must be repacked in their original condition. This is the only way to ensure that the crates can be stacked on top of each other.

10. Cleaning and maintenance

We recommend an annual inspection of the façade. Clean with water and a sponge or brush. If tiles are heavily soiled, an alkaline-free, synthetic cleaning agent may be used. Do not use any strongly alkaline or acidic cleaning agents, baking soda, caustic soda or an abrasive scouring agent.
