Injection molding is one of the most widely used manufacturing processes for producing plastic parts in large volumes. It offers excellent repeatability, high production efficiency, and the ability to create complex geometries. However, even with advanced molding equipment and high-quality molds, defects can still occur during production.
Injection molding defects not only affect the appearance of plastic products but can also compromise their mechanical performance, dimensional accuracy, and overall quality. Understanding the causes of these defects and implementing effective corrective measures can significantly improve production efficiency and reduce scrap rates.
This article explores the most common injection molding defects, their causes, and practical solutions for prevention and improvement.
