DESIGN OF INJECTION-MOLDED PLASTIC PARTS, ACCORDING TO ISO STANDARDS

Abstract


Currently, the trend among automobile manufacturers and automotive subsystem producers is rapidly shifting towards reducing manufacturing costs, driven by increasingly intense competition. One of the solutions to achieve this is replacing metal materials with plastics, which offer lower costs and a more efficient mass-production process. This paper presents part of the design methodology for an injection-molded plastic part by calculating the precision grade and applying tolerances in accordance with ISO 20457:2018. Additionally, it introduces a tool designed to facilitate the designer's work in this area. This tool leverages information from the standard, automating the necessary steps for implementation while providing supplementary explanations and examples that extend the standard’s information.
