What are the defects in plastic?

Question

Accepted Answer

Plastic defect is a flaw or imperfection in a plastic material that affects its quality and performance.

Plastic defects can include air bubbles, warping, sink marks, flow lines, and voids.
Air bubbles are trapped pockets of air within the plastic material.
Warping is the deformation or twisting of the plastic material.
Sink marks are depressions on the surface caused by uneven cooling.
Flow lines are visible lines or streaks on the surface due to uneven flow of plastic during molding.
Voids are empty spaces or gaps within the material.
