Detailed Description

Describes irregular wall thickness screw boss issues found during injection molding design analysis.

The irregular wall thickness screw boss issues refers to the challenge of molding features with deviating from the nominal wall thickness. Irregular wall thickness screw boss can cause non-uniform cooling and fails applied loads. Therefore, it is recommended to maintain screw boss's thickness variance from 40% to 60% across the nominal thickness to minimize the risk of sinking or fracture.

Contains screw boss that fails the following conditions:

\[ R_{min} \leq \frac{D_b-D_h}{T_n} \leq R_{max} \]

\[ \begin{aligned} & \small D_b - \text{analyzed boss outer diameter} \\ & \small D_h - \text{analyzed boss core hole diameter} \\ & \small T_n - \text{nominal wall thickness} \\ & \small R_{min} - \text{minimum boss to wall thickness ratio} \\ & \small R_{max} - \text{maximal boss to wall thickness ratio} \\ \end{aligned} \]
