Bendywood® should always be bent around a mould. To this end you can use clamps, presses, tension belts, etc. and then you should wait until the bent form has stabilized, best by drying it to 8% final moisture content. Pictures of moulds can be seen on our website under the rubric "Bending moulds for Bendywood®".
When loosening the bent part from the mould, the curve will slightly open up. Also see on our website under "Spring-back after being taken from the mould".
At a moisture content of about 12% Bendywood® can be bent:
- up to a radius of 1 : 10 if not jointed in length (e.g. a 10 mm thick section up to a radius of 100 mm)
- up to a radius of 1 : 20 if jointed in length (e.g. a 10 mm thick section up to a radius of 200 mm)
The dryer the Bendywood®, the more dimensionally stable it is.
Only humidify dry Bendywood® when you need to bend it to a tight radius.
Bending radii up to a radius of 1 : 30 can also be reached when the wood has a moisture content of 8%.
Should you be in need of raising the moisture content, the Bendywood® should be placed between two layers of moist cardboard. A few spacers should be positioned above and below the wood in order to avoid direct contact with the cardboards. Finally, the whole lot should be covered with a plastic foil and left at rest for 1 - 2 days and nights: in this way the moisture content is raised to about 12%, the ideal humidity for bending.
Using this technique (referred to as "Sandwich Method") the Bendywood® absorbs humidity form the air without getting wet.
BENDYWOOD® MUST NOT BE PLUNGED INTO WATER OR COME IN DIRECT CONTACT WITH WET MATERIAL.
The ingress of water will make the wood swell and – in case of jointed parts – it can cause the glued joints to open up.
