Visual inspection of injection‑molded components is essential for ensuring that every part meets the functional, cosmetic, and regulatory requirements expected in high‑reliability industries like pharma, biotech, and medical devices. Because molding defects can directly impact assembly performance and patient safety, inspection focuses on identifying:
- Surface defects: flow lines, sink marks, weld lines, burn marks, splay
- Structural issues: short shots, warpage, incomplete features, cracks
- Contamination: embedded particles, fibers, discoloration, foreign material
- Dimensional anomalies: flash, gate vestige irregularities, deformation
Effective programs rely on controlled lighting, standardized inspection criteria, and qualified inspectors capable of detecting subtle variations. High‑quality visual inspection reduces scrap, prevents downstream failures, and ensures consistent part performance across production lots.
