Abstract
diaphragm thermoformer for thermoforming a wood fibres-thermoplastic composite material such as wood fibres and polypropylene comprises at least one pair of flexible diaphragms 26 mountable adjacent a mould 29 on one side of the pair of diaphragms and an inlet into and outlet from a space between the diaphragms enabling hot fluid to be circulated between the diaphragms to heat a wood fibres-thermoplastic composite material placed between the diaphragms and the mould. A space is on the other side of the pair of diaphragms. A fluid under pressure may be introduced into the space, to force the diaphragms and the wood fibres-thermoplastic composite material against the mould after heating and cause the removal of the hot fluid from between diaphragms 26, to shape the wood fibres-thermoplastic composite material to a mould.
