Hettinject is easily integrated into workflows. All conventional fittings based on a 5 mm screw can be used in furniture making. Unlike methods with integrated glue, the fact that the glue is supplied separately offers enormous advantages for process control, as the amount and type of glue can be precisely matched with the board. In addition, the glued dowel automatically compensates tolerancesfrom manufacture of the board. Even the hole drilled in the board need not meet any particular demands. The lower face layer remains untouched, leaving 1 mm of air under the dowel. This prevents the dowel pressing through or marking the lower face layer. Through just one channel in the dowel the glue automatically spreads to the attachment points via a number of other flow channels.
