What is Troubleshooting Tear Drop Defects about?

Tear drops are tear drop-shaped irregularities on plastic surfaces caused by entrapped air. They can be caused by air trapped in engraved areas, grooves or depressions in molds. To remedy this, reduce injection speed in critical areas, improve mould venting in locations like weld lines and depressions, and apply a vacuum to the mould.
