Abstract

PURPOSE:To provide a high quality formed product that keeps only useful forming strain through the forming process by forming molten resin with applying minute vibration of ultrasonic vibration, high frequency vibration, etc. CONSTITUTION:In the process of the injection of an injection molding machine A that produces desired formed products by intermittently injecting mold resin into the cavity 1 by the action of an injection mechanism, the molten resin in a molten resin repository is formed as it is continuously given ultra-sonic vibration by the action of an ultra-sonic vibration source 9. By this arrangement harmful forming strain in the molten resin that is poured into the cavity 1 is eliminated and very dense formed products are obtained. Incidentally instead of the ultra- sonic vibration source a high frequency vibration source can be used.
