Plastic Part Design Fundamentals for Engineering and Manufacturing

Designing plastic components requires a solid grasp of material behaviors, manufacturing constraints, and structural requirements. This text-based course guides you through the foundational principles of engineering robust plastic parts suitable for real-world production. You will explore essential concepts step by step, progressing from basic polymer terminology to practical design rules. What you'll learn: Understand core polymer classifications, material properties, and selection criteria for engineering plastics; Apply fundamental design for manufacturing rules including uniform wall thickness, draft angles, and rib design; Identify and prevent common injection molding defects such as sink marks, warpage, and weld lines; Design functional features including snap fits, bosses, living hinges, and parting lines; Evaluate modern considerations such as sustainable plastics, recycling standards, and rapid prototyping workflows; Analyze product case studies through detailed written breakdowns. The curriculum begins with fundamental definitions and material mechanics before walking through detailed feature-level engineering guidelines and practical case assessments. Designed for beginner engineers, product designers, and technical enthusiasts, this course requires no prior experience in plastic molding.
