Course Description

Eliminate recurring defects, boost part quality, and achieve efficient, waste-free production of plastics even in high-pressure environments!

Recurring defects, long troubleshooting cycles, and wasted production time, these challenges drain productivity and profits. This course is your shortcut to mastering how to identify, analyze, and eliminate common injection molding defects like air traps, sink marks, weld lines, jetting, and more while optimizing cycle time and reducing operational cost.

Led by Enric Pascual, a seasoned injection molding expert with real-world industry experience, this practical training will help you:

  • Solve defects faster with a structured problem-solving approach, defect visualization, and root cause analysis.
  • Leverage simulation tools like Moldex3D to predict, test, and validate fixes before hitting production.
  • Cut down cycle time and energy use by adjusting process parameters and applying smarter mold and part design strategies.

Why should you view this course?

Injection molding professionals are under constant pressure to deliver high-quality, defect-free parts and fast. But in real-world conditions, repeated defects like weld lines, air traps, sink marks, or burns continue to show up despite multiple adjustments. Troubleshooting is often time-consuming and based on trial and error, leading to lost production hours, excessive scrap, and unresolved root causes. Many still struggle to connect how mold design, material selection, and processing parameters interact to cause these failures.

This course is designed to break that cycle giving you a structured, efficient method to identify, resolve, and prevent defects with clarity and confidence.

You'll gain:

  1. A systematic troubleshooting framework to pinpoint and fix the most common injection molding defects saving time and material waste.

  2. Clear understanding of root causes by connecting defect types to mold design, process parameters, and material-related issues.

  3. Skills to use simulation tools effectively (like Moldex3D) to predict issues, validate solutions, and reduce dependence on guesswork.

  4. Techniques to improve cycle time and energy use while maintaining part quality and reducing operational costs.

  5. Real-world case studies to show how experts tackle defects in practice and how you can replicate those strategies.

Who should join this course?

  • This course is ideal for professionals involved in injection molding, part quality, and production efficiency, including:

    • Process Engineers and Injection Molding Technicians who troubleshoot defects on the shop floor
