Dibond can be cut with a circular, band or jig saw. More detailed information on request.


Dibond can be drilled with twist drills normally used for aluminium and plastic and using standard metal drilling equipment.

Dibond can be easily routed on conventional equipment (universal, vertical, horizontal routing machines). Plastic or wood vice jaws should be used when chucking the workpieces to avoid pressure marks on the surface. High-speed steel or carbide tipped cutters suitable for cutting Dibond or aluminium have a wide tooth pitch, radiused and smooth grooves and small lip angles.

Edge trimming
A file with a rasp-like cut can be used to file roughly cut contours.

Dibond can be cut to size with mechanical fret saws, profile milling machines, jig saws.

Routing and folding technique

Dibond composite panels can be shaped by an extremely simple method. This method of routing and folding enables the manufacturer to produce pieces in many and varied shapes and sizes. A V-shaped or rectangular groove is routed into the reverse surface of the Dibond panel by means of a disk or end milling cutter. Part of the plastic core and the front cover sheet are left untouched. Due to the reduced thickness, the material can now be folded by hand and no bending/folding press is necessary. The folding radius is determined by the shape and depth of the groove. Routing can also be done with panel saws equipped with a routing appliance for Dibond, or with a hand milling machine.

The advantages of the folding and routing technique are:

With a guillotine, padding on holding-down clamp required, causes slight indentation in the cover sheet.

With a folding / bending press or a brake press

Bending / folding
With roll bending machines. Please only use perfect ground rolls must be used. More detailed information on request.

Dibond panel 2 and 3mm thick can be punched with steel band tools. Dibond panels of all thicknesses can be punched with conventional sheet punching machines. For clean cuts please use evenly ground tools and a narrow blade clearance. Causes slight indentation on the panel cover sheet.

With conventional equipment and rivets e.g. blind rivets. For exterior use please take expansion into account.

With the usual metal adhesives. There is no adhesion on front-end plastic edges. For indoor use please apply double sided tapes.

With conventional stainless wood, sheet metal or metal screws. For exterior use please take expansion into account.

With serrated corner and butt joint sections for 3 and 4mm thick Dibond panels.

Hot air welding has proved suitable for joining Dibond. The plastic core and plastic welding rod are heated and welded with electric hot air.

Lacquering / spray painting
With air drying acrylic or two component polyurethane lacquer.

Application of film lettering
The panel must be clean and free of dust and grease.

Screen printing
With the usual screen printing inks. The panels must be clean and free of dust and grease - for paints and processing methods please refer to our screen printing leaflet.

Whether the surface is treated manually or by machine, lacquer does not peel off when cast or calandered self-adhesive film is changed. Photo mounting with adhesive tape or moist with dispersion adhesive. The panel must be clean and free of dust and grease.
