Effect of non-unifrom wall thickness of plastic parts

πŸ‘‰ Sink marks result from a wall yielding to the shrinking interior mass.

πŸ‘‰ The already cooled sections will not yield to the shrinking action of the cooling interior mass causing voids in the thick portion of the part.

πŸ‘‰ A part with non-uniform wall thickness will cool unevenly, resulting in high molded in stress.

πŸ‘‰ Concentrated stress at the junction of high and low shrinkage areas may cause a part to warp.
