Common Injection Molding Defects and How to Fix Them

Injection molding defects often result from small process variations. Below are common issues and solutions:

Dimensional Instability

Cause: Inconsistent pressure or temperature
Solution: Stable parameters and mold optimization

Bubbles or Silver Streaks

Cause: Moisture or poor venting
Solution: Material drying and vent improvement

Surface Defects

Cause: Uneven flow or cooling
Solution: Gate and cooling system optimization
