For reliable processing, you should always apply solid aluminium edgings with PUR hotmelt adhesive and heat them to approx. 45 - 50 °C first. To do so, use a veneer press or place hot air blowers underneath the edging table of the edgebanding machine. Before milling, both sides of the edging roll - i.e. the protrusions to be milled - should be treated with a cloth wet with Teflon spray. To complete this process you can then sand the radius / chamfer with 240 grit sandpaper and seal the milled edge with hard oil.
