Troubleshooting Focus: Flowlines

Flowlines are wavy or rippling surface defects. They can appear as lines, streaks, or patterns, but are consistent with the material flow within the cavity of the mold. They occur when the molten plastic passes through the mold or gate and can have many causes and corrective actions.

If you have more questions about flowlines or other molding defects, talk with your Eastman technical service representative—and ask how to receive your free copy of our Injection Molding Troubleshooting Guide
