The same defect comes back every week? The problem is the method, not the machine
In many plants a defect is answered by changing several parameters at once. The defect disappears and returns a week later, because nobody established its cause. This course teaches diagnosis in five steps: describing the symptom, collecting facts, forming hypotheses, testing one variable at a time and setting a lasting standard. The same method works for short shots, warpage and cracks.
- You carry out diagnosis in fixed steps and determine the processing window.
- You recognise a raw material batch change, check ring wear and a failed heater band in the controller data.
- You keep the process stable when processing recycled material.

Who is this course for?
Process engineers, experienced operators, quality control staff and production managers who know the basics of injection moulding and are responsible for eliminating part defects.
What you will be able to do
- Diagnose short shots, flash, streaks, sink marks, warpage and cracks.
- Separate causes in the raw material, the machine and the mould.
- Match the dryer to raw material consumption and accept recycled material batches with control.
- Apply lockout/tagout (LOTO) during diagnosis and mould changes.
- Keep a diagnostic card that becomes a standard in your plant.
Seven practical topics
The logic of diagnosis; raw material and process stability (PP, rPP, HDPE, ABS, SAN); filling and surface defects; shrinkage, warpage, stresses and cracks; the machine and the mould as sources of problems; health and safety during diagnosis and mould changes; cases from production and the diagnostic card.
Learning materials you can use at work
Cases from production described step by step, a diagnostic card template for your plant, checklists and review questions with explanations.
Certificate and assessment
After completing the course you receive a Rolbatch Academy certificate. The final quiz has 28 questions, with an explanation for every answer.
