The elliptical injection molding item which was formed from the thermoplastics which are strengthened with the long fiber, especially, process in order to produce the screw and the screw stick

摘要

(57) Abstract As for this invention, fusion ones of the long fiber-reinforced thermoplastics, from the injection molding machine, through the gate, at least injecting to one gate and in one which possesses overflow cavity at least, the elliptical injection molding item, especially, being manner in order to produce the screw and the screw stick by restoration the said cavity, excluding actual restoration job, until array of axial direction of the above-mentioned fiber it becomes dominantly as a result of the shear flow, aforementioned fusion ones with the flow of unidirectional, through aforementioned overflow, in fusion thing akiyumiyuretaIt regards the manner which features that the process which it forces is had. In addition as for this invention, it relates to also the elliptical injection molding item itself.
