Understanding Injection Molding Defects

Injection molding defects are flaws that compromise a part’s appearance, performance, or dimensional accuracy. While some defects are cosmetic, others can impact structural integrity, function, or downstream assembly, making early detection and prevention critical in production environments.

Understanding why defects occur allows manufacturers to make informed decisions around material selection, mold design, and process optimization. A proactive approach reduces scrap rates, improves consistency, and helps maintain production schedules.
