Even the best‑designed molds and machines can produce defects under poor management. Part problems cost processors time, money, and ultimately customer trust. That’s why strong troubleshooting skills are essential.
Learning to identify and correct the most common and costly molded-part problems gives you an invaluable competitive edge. Featuring plastics pioneer and veteran industry educator Don Paulson, our troubleshooting course provides insider information on the cause and effect method of problem analysis. Injection Molded Part Problems & Solutions with SkillBuilder is one of Paulson’s most popular programs for a reason—it teaches molders, designers, and supervisors how to identify, analyse, and correct the 11 most common and costly injection molded-part defects using a scientific approach.
Structured, scientific instruction combining theory and visualisation has been shown to help learners understand the complex relationships between machine controls, plastic behaviour, and molded-part properties. In this course, part defects are described and analyzed to show how each develops. Then machine control adjustments and/or tooling and part-design changes to correct specific defects are explained in detail.
Integrating SkillBuilder™ lab lessons, this course leads students through guided simulations. Learners practice solving real, relevant molding problems on a virtual injection-molding machine without tying up production equipment or risking damage to molds. These Skillbuilder lessons cover issues like burn marks, flash, sink marks, voids, weldlines, and warp. Learners can adjust pack/hold pressure, melt temperature, fill rates, clamp force, and more, seeing the results instantly in a realistic 3‑D environment.
This hands‑on practice builds confidence and accelerates learning for a wide range of roles: setup personnel, foremen, process engineers, supervisors, and molding managers. Anyone responsible for part quality or machine performance will benefit from the cause‑and‑effect method of problem analysis. And by the end of the training, learners can recognise and correct defects such as:
- Burn marks
- Cracks and part breakage
- Dimensional variations
- Flash
- Jetting
- Short shots
- Sink marks
- Splay
- Voids
- Warp
- Weldlines
With 15–20 hours of training and 7 SkillBuilder labs, the course delivers a deep, practical understanding of scientific molding principles. This revolutionary training package features a fully functioning injection-molding machine simulator with crisp 3-D graphics and complete molding animations.
If you’re looking to hone your skills, strengthen teams, reduce scrap, and improve consistency, this course is among the most effective training investments available. Download the course brochure here.
