PRODUCT INFORMATION
8.3 Processing
8.3.1 Cutting
• For cutting, we recommend the use of carbide- or diamond-tipped saw blades, as also used for the
processing of DUROPAL HPL.
• With DUROPAL HPL-Solid, a lower feed speed should be used than for DUROPAL HPL elements.
• For compact laminates with décor on both sides, damage to the lower décor layer can be effectively
avoided by changing the exit angle. This can be achieved by varying the height setting of the saw blade.
• Good results can also be achieved by placing plywood, hard fibre panels or DUROPAL HPL under the
panels.
• Optimum cut quality of the lower edge can be achieved by using a pre-scoring device.
8.3.2 routing and drilling
• For routing, we recommend carbide- or diamond-tipped routers with high rotational accuracy, in order to
minimise chatter marks. The use of special router heads has proven useful for processing large quantities
of panels.
• Due to the high cutting pressure, secure tool guides and fences are essential.
• Cutting marks on the milling surface are unavoidable. These can be reduced by using a mechanical
router and by milling in the same direction. Any remaining marks can then be removed by sanding and
polishing.
• Further improvements in the appearance of the edge can be achieved by treatment with silicon-free
furniture oils.
• Projecting corners and edges should be chamfered in order to avoid the risk of injury.
• Drills used for plastics are most suitable for drilling.
• Splintering of the DUROPAL HPL-Solid on the outlet side can be avoided by working on a firm surface
and gradually reducing the feed speed.
• Drills with a tip angle of 50-60° should preferably be used for through-holes.
• Ensure when centre-drilling that a minimum of panel material remains.
• This requires a minimum remaining thickness for blind holes of at least 1.5 mm, and at least 3 mm
for holes parallel to the surface.
• In all DUROPAL HPL-Solid, threads can be cut and self-tapping screws used without any problems.
