Abstract

Injection molding is the most commonly used process that uses plastic material. Today, the uses of plastic material are continuously increasing, and the range of application is also being extended by the development of novel materials. An inline skate consists of 4 components: the boot, frame, wheel and brake. Among these components, the frame is the most critical. The injection formability for a variety of injection materials for inline skate frames was studied. We also studied the injection formability of the product for various sizes of the runner and gate. In this study, injection molding analysis was performed using MOLDFLOW, and structural analysis was performed using ANSYS.

플라스틱 재료를 사용한 가공법 중에서 가장 보편적인 가공법이 사출성형이다. 오늘날에는 플라스틱 재료의 활용도는 지속적으로 증가하고 있으며, 신소재 등의 개발로 그 적용범위 또한 확대되고 있다. 인라인 스케이트는 4 가지 구성품으로 이루어진다. 그 4 가지 구성품은 부츠, 프레임, 휠, 브레이크로써 프레임이 가장 중요한 부품이다. 사출 재질에 변화에 따른 사출 성형성을 알아보았다. 런너와 게이트의 치수 변화에 따른 제품의 사출 성형성을 알아보았다. 본 연구에서는 Moldflow를 이용해서 사출성형 해석을 수행하였다. ANSYS를 이용해서 구조해석을 수행하였다.
