| titleOfInvention |
A method and a system for manufacturing shaped objects of wood dust |
| abstract |
It is attractive to produce small wooden objects, e.g. pipe heads or furniture handles, by a moulding process based on an aqueous suspension of wood dust, but by the attempts made so far the process time has been so long that it has not been economical to produce objects with a required high quality by such a technique; one important thing is that the moulded objects should be dried out to a very low content of water. With the invention a very short process time is achieved by the use of injection mould parts (32), in which electrodes (34) are placed for subjecting the moulding cavities (8) to a HF-heating field such that both a rapid curing of a heat setting glue agent in the aqueous wood dust mass and a rapid driving out of the major part of the water will be obtained. The moulding cavities (8) have exhaust channels (24, 26) for the steam, and the means (6) for holding the mould parts (2 and 4) together are designed so as to be able to be effective by the very high steam pressure that is developed in the mould cavities. |
