[QUOTE="Pug}{maN, post: 6740140, member: 619705"] i have seen it done, they get it wet with something (chemical mix) till its flexible, then shape it to whatever.... just like drywall MDF, or medium density fibreboard, is a common replacement for wood. It is usually manufactured as flat sheets, and is a stiff, rigid, inflexible material that is difficult to bend into the sort of complex shapes often required. It has now been found that by impregnating MDF with ammonia (used in anhydrous - that is to say, dry gaseous - form) the MDF can be made relatively plastic, and in its plasticised state can quite easily be pressed or bent into almost any shape required.
