Some common molding defects that can occur in automotive plastic products include sink marks, flash, warping, air traps, short shots, and burn marks. Sink marks are depressions on the surface caused by uneven cooling or insufficient material flow. Flash is excess material that escapes from the mold, resulting in thin, unwanted edges. Warping occurs when the product becomes distorted due to uneven cooling or shrinkage. Air traps are pockets of trapped air that create voids in the product. Short shots happen when the mold does not completely fill with material, leading to incomplete parts. Burn marks are discoloration or blackening on the product caused by overheating or excessive material exposure to the mold surfaces.
Some of the different molding defects that can occur in automotive plastic products include sink marks, warpage, flash, short shots, gas traps, and flow lines.
There are several common molding defects that can occur in automotive plastic products. These include sink marks, which are depressions on the surface of the product caused by uneven cooling or insufficient material flow. Another defect is warpage, where the product becomes distorted or bent due to uneven cooling or improper mold design. Flash is another defect, which refers to excess material that is squeezed out of the mold cavity and forms a thin layer on the product's surface. Other defects include air traps, flow marks, and weld lines, which are all caused by improper material flow during the molding process.
