Both the shrink mark and shrinkage porosity are defects of injection products due to the molding shrinkage at thick walls where no sufficient follow-up compensation is made. During the injection process, the surface layer of products often condenses first, followed by the center layer, which will cause sinking on the surface of parts with thick [...]
as an injection molding engineer, he should be very familiar with welding mark, the thread mark formed at the front confluence of two or more melt flows in the cavity is called welding mark or welding line. […]
