Bendywood® -    The Bending Wood Without Steam

Bendywood® lipping
Always
bend the Bendywood® 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".   

When loosening the section from the mould, the curve will slightly open up. This is not a problem for sections that subsequently are being fixed onto a stable support. It only is a problem for sections that are meant to be freestanding. Therefore these sections need to be overbent , i.e. the radii need to be kept proportionally smaller. Also see on our website under "Spring-back after being taken from the mould".

At a moisture content of about 12% Bendywood® not jointed in length can be bent up to a radius of 1 : 10 (e.g. a 10 mm thick section can be bent up to a radius of 100 mm).

The dryer the Bendywood®, the more dimensionally stable it is.

 

IMPORTANT:
Only humidify dry Bendywood® when you need to bend it to a tight radius.
Bending radii up to a radius of 1 : 40 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 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 two days and two nights: in this way the moisture content is raised to about 12%, the ideal humidity for bending. 

Sandwich Method Bendywood®

Using this technique (named "Sandwich Method") the Bendywood® absorbs humidity form the air without getting wet.

ATTENTION: 
Bendywood® MUST NOT BE PLUNGED INTO WATER OR COME IN DIRECT CONTACT WITH WET MATERIAL.

A possible infiltration of water will make the wood swell and – in case of jointed sections – it can cause the joints to come apart.
