发明名称 MICRO-FILLER WHICH IS FORMING SURFACE OF RESIN-INJECTION MOLDING PRODUCT & INJECTION MOLDING MACHINE USING THE SAME & INJECTION MOLDING METHOD FOR THE SAME
摘要 A micro-filer and an injection molding machine using the micro-filer and an injection molding method are disclosed. The micro-filer and an injection molding machine using the micro-filer and an injection molding method includes a micro-filer; an injection molding machine comprising metal molds in which micro-filers are distributed in resin and the cavity is formed to have the resin injected, thereby injection molding a product and a magnetic force generation unit for generating a magnetic force strong enough that the magnetic force is applied to the micro-filers distributed within the resin and the micro-filers are distributed concentratedly at one side of the injection molded product of resin; and a method of injection molding comprising a resin injection step in which resin having magnetic micro-filers distributed therein is injected, a magnetization step in which a magnetic force is generated in one side direction of metal molds and applied to the micro-filers within the resin for concentratedly distributing the micro-filers on one side of the resin, a cooling step in which the resin is cooled and hardened in the metal molds, and an extraction step in which the hardened resin is extracted from the metal molds.
