FIELD: wood-working industry. SUBSTANCE: operation of plasticization is performed at application of electric voltage to the wood material, and the process of compression is accomplished by wood extrusion at continuous feed of material to the extruder. Operations of plasticization and compression are accomplished with imparting of vibration to the treated wood material and may be performed simultaneously. Vibration is produced by a system of extruder body oscillations including different frequencies, from low to high ones. EFFECT: low duration of process, ecological purity, enhanced quality of produced items. 3 cl, 1 ex |
