친환경 포장재 적용을 위한 플라스틱 사출 스프링 설계 파라미터 연구

Abstract

Recently, environmental interest in packaging materials has been increasing as the manufacturing industry related to packages has diversified and increased. As the life cycle of products is shortened, the amount of industrial waste is also increasing. As environmental protection issues have emerged as an international concern, manufacturing companies are corporate social responsibility (CSR) and conducting various research activities to reduce the impact of industrial waste on the environment. Companies that manufacture and sell products should develop and produce products by devising ways to reduce environmental pollution, such as recyclable products and products that can be separated and discharged. In this paper, the method of separating and discharging cosmetic packaging materials was studied. The design parameters of plastic springs that can replace metal springs used in cosmetic pumps were studied. The mechanical properties of injection springs according to the design shape were pre-validated through structural analysis and the experimental results were obtained through prototyping. In addition, a plastic material that satisfies and replaces the mechanical properties similar to metal springs was tested, and the design and materials that could be reflected in the product were selected.
