Plastic mold design
Plastic mold design
The Plastic Mold Design course is an advanced training program focused on the design and development of plastic injection molds—essential tools in mass production across automotive, consumer goods, electronics, and medical devices industries. This course equips learners with the theoretical foundation and practical skills to design high-performance, manufacturable, and cost-effective molds. With a strong focus on mold mechanics, thermoplastic behavior, tooling elements, and CAD/CAM integration, this program prepares engineers to meet real-world production challenges.
🔍 What You Will Learn
The course dives deep into mold components, design methodology, and part analysis. Students learn to evaluate part geometry for moldability, determine parting lines, select appropriate gating systems (hot or cold runner), and design essential elements like cores, cavities, ejectors, sliders, and cooling systems. Focused sessions cover mold flow analysis, shrinkage compensation, and material selection strategies. Learners are trained in industry-standard tools like Siemens NX, CATIA, Creo, or SolidWorks, with practical assignments to reinforce every concept.
🧪 Tooling Materials & Manufacturing
Beyond design, the course also introduces tool steel selection, heat treatment processes, and machining techniques like EDM, CNC milling, and polishing. Understanding how mold components are manufactured helps designers ensure feasibility and maintainability. The course also covers mold life estimation, maintenance practices, and cost control in tooling development.
🛠️ Mold Elements & Design Techniques
A major part of the training is understanding the function and interaction of mold components:
Cavity/Core design principles
Ejection systems: pin, sleeve, stripper plate, air ejectors
Cooling system layout and flow channel optimization
Runner and gate design: submarine, edge, direct
Venting strategies to prevent short shots and defects
Learners will practice complete mold design for real components and simulate mold performance to ensure balanced filling, optimal cooling, and efficient part ejection.
⏳ Course Duration & Structure
The course is available in various formats to suit different types of learners, including fresh graduates, working professionals, and industry upskillers. A standard full-time course may run between 3 to 6 months, with intensive daily sessions and hands-on project work.
🧭 Industry Applications
Plastic mold design is a core function in mass production industries such as automotive interior parts, electronic housings, medical devices, packaging, and household goods. This course trains professionals to become mold designers who can collaborate with part designers, tooling engineers, and manufacturing teams to deliver optimized tooling for injection molding.
