Are resin tables prone to sink marks during injection molding?
Resin tables, like many plastic products, can be prone to sink marks during the injection molding process. Sink marks are surface imperfections that occur when the material cools unevenly, causing depressions or dimples. This issue is particularly common in thicker sections of the resin table, where the cooling rate is slower. Factors such as improper mold design, insufficient cooling time, or incorrect material flow can exacerbate the problem. To minimize sink marks, manufacturers often optimize mold design, adjust processing parameters, and use materials with better flow properties. Understanding these challenges is crucial for producing high-quality resin tables with smooth, defect-free surfaces.
