1.Define the requirements and constraints for each component. This includes things like size, shape, functionality, material, manufacturing method, and assembly requirements.2.Create concept designs for each component, using sketches, surfacing, or digital models.3.Create 3D parametric models of each component using CAD software. Ensure that each component's A-surface (visible surface) meets the design specifications without any clash, undercut, or deviation.4.Design the B-side features of each component, such as snaps, dog houses, locators, and supporting ribs, while considering any undercuts or lifter/slider usage. These features are important for assembly and often require careful consideration to ensure that they are both functional and manufactural.Conduct draft analysis and ensure that each part is feasible for tooling. This involves analyzing the angles and directions of the surfaces to ensure that the part can be easily and effectively molded or formed. Design the plastic tooling for each component, including details such as the core, cavity, slider, and lifter concepts. This requires an understanding of injection molding techniques and the ability to identify potential issues such as warping or sink marks.Conduct gap and flushness checks, and evaluate the designs for manufacturability using DFM (Design for Manufacturability) and DFA (Design for Assembly) principles. These checks help to identify and resolve any potential issues early in the design process. Develop a locating strategy and assess packaging feasibility, ensuring that each component can be easily located and assembled within the product. Design mounting schemes and assembly sequences, considering the use of locators, fixations such as dog houses and snaps, and other concepts to ensure proper alignment and function. Basis knowledge stack up analysis.
