Design for manufacturing for injection molding

Learn injection molding design for manufacturing, from draft angles and undercuts to snap hooks, for designers and engineers with 3D modelling skills.

<h2>About this course</h2>In this course, you learn how design for manufacturing (DFM) applies to injection molding, a fundamental process of modern manufacturing. After an introduction to DFM for injection molding, you work through the core design rules: dealing with sharp corners, adding draft angles, handling undercuts, and choosing surface finishes.You then move into more specialist features, including crush ribs, snap hooks, and ribs and support material, and learn how mold modifications affect a design. The section also covers the practical details that connect your CAD model to the tool: gates, ejector pins, and parting lines, the file types used in production, and adding molded text to parts. Together, these lessons help you design parts that are functional and optimized for the molding process, and a quiz checks your understanding.The second section applies these concepts in two case studies. First, a hinge case study shows the DFM principles at work in a real-world context and how molding decisions shape the finished part. Then an electronics enclosure case study brings together the molding aspects covered earlier, before a conclusion ties the key points together for your own injection molded designs.<h2>Who should take this course</h2>This course is for you if you have some 3D modelling knowledge and want to improve your manufacturing skills for injection molded parts. It suits product designers, mechanical engineers, engineering students, and hobbyists who design parts in CAD for injection molding. It is especially useful if you are preparing parts for molding and want to understand how draft, undercuts, ribs, snap hooks, gates, ejector pins, and parting lines should shape your design decisions.<h2>Prerequisites</h2>You should have some 3D modelling knowledge before starting. SolidWorks 2022 or later is recommended, and earlier versions can be used, but access to SolidWorks is optional. The course is rated easy.
