Main causes of sink marks and voids in plastic parts, emphasizing part thickness variation and uneven shrinkage. It suggests that the key to addressing these surface quality problems lies in improving mold design and modifying process settings. The proposed solutions include adjusting the cooling layout, gate location, and gate diameter in the mold design, as well as making process setting modifications such as increasing packing time, decreasing melt temperature, and increasing cooling time. These changes aim to reduce the occurrence of sink marks and voids.
