METHOD AND APPARATUS FOR FORMING ITEMS MADE OF PLASTIC MATERIAL WHEREBY THE PLASTIC MATERIAL IS HEATED BY ULTRASONIC VIBRATIONS

摘要

For formed article (one), be made of polymeric material, including following operation: make a large amount of polymeric material (14) and predetermined fluidised form or viscous state be suitable for obtaining plastic article (one) and formed required for predetermined shape the number of polymers material (14). Under conditions of sequence is so that the substance enters default viscosity, this method needs to send the number of polymers material (14) of ultrasonic activation.
