how to resolve the sink marks issues by design scheme.

how to resolve the sink marks issues 

sink mark evaluation standard                           the guidelines for improve the sink                                                                                     mark by decrease plastic 

∅E ≤ 1.18A                                                                                                  ∅E ≤ 1.18A ,         D＞10C







Example :

The maximum thickness in the red area is 2.55mm, which is more than 1.18 times the average wall thickness, so sink marks may occur in the red area.


decrease plastic  on the red surfaces.


this tthicken analysis result that it is decreased plastics below,  the maximum thickness from 2.55mm to1.70mm, so the sink marks can be avoided on the product surface.
