Plastic injection molding technical data and secondary operations
| Rib thickness and rib height | Rib thickness is recommended to be 60% to 80% of nominal wall thickness; Rib height is recommended to be 3-4 times of nominal wall thickness |

|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Plastic injection mold draft | 0.5 -2 degree for the wall side which shrinks onto the mold in part releasing | ||||||||||||||||||
| Plastic injection molded part wall thickness consideration | Uniform wall thickness is recommended to reduce Sink marks, Residual stresses, Voids, Warpage. 0.06″ – 0.16″ is considered to be normal wall thickness range. | ||||||||||||||||||
