Abstract: PURPOSE: A method for manufacturing an assist handle grip for a vehicle is provided to prevent a surface fault of the assist handle grip by forming the assist handle grip using polypropylene with an injection molding process. CONSTITUTION: A predetermined amount of molten polypropylene resin(20) is filled in a mold(30). Nitrogen gas is injected into the molten polypropylene resin(20) through a nozzle. A gas channel(40) is formed in the molten polypropylene resin(20) by nitrogen gas. Then, remaining polypropylene resin(20) is filled in the mold(30) while the molten resin maintains a shape corresponding to the mold(30) by gas pressure. Then, a cooling process is carried out while maintaining gas pressure of 0.4-0.5MPa in molten polypropylene resin(20). After shutting off gas, an article is ejected from the mold(30).

Abstract: PURPOSE: A manufacturing method of a cup holder for a vehicle is provided to support a container stably without vibration and noise in contacting a cup or a can to the cup holder by double injection molding, and to increase the productivity by reducing manufacturing process. CONSTITUTION: A cup holder is composed of a core part forming an inner layer, and a skin part forming an outer layer and surrounding the core part. The core part is injection-molded by PP(polypropylene) resin, and the skin part is injection-molded by TPE(Thermoplastic elastomer). The inner layer is formed with injection-molding PP resin(S10). A mold is turned at an angle of 180 degrees after cooling as 70-80%, and the outer layer is formed with injection-molding TPE resin(S14). The cup holder is separated from the mold after cooling(S16). The core part made of PP is mounted integrally with the skin part made TPE. Manufacturing process is reduced, and the productivity is increased with double injection molding.

Abstract translation: 目的：提供一种用于车辆的杯架的制造方法，其通过双重注射成型稳定地支撑容器而不会使杯或罐与杯架接触而产生振动和噪音，并且通过减少制造过程来提高生产率。 构成：杯架由形成内层的芯部和形成外层并围绕芯部的皮肤部分组成。 核心部分由PP（聚丙烯）树脂注射成型，表皮部分由TPE（热塑性弹性体）注射成型。 内层由注模PP树脂形成（S10）。 冷却后，模具以180度的角度旋转为70〜80％，外层由注塑TPE树脂形成（S14）。 冷却后杯架与模具分离（S16）。 由PP制成的芯部与TPE的皮肤部分整体安装。 制造过程减少，双重注射成型提高生产效率。
