Detailed Description

Describes high screw boss issues found during injection molding design analysis.

The high screw boss issues refer to situation when the height of the boss is much greater compared to the thickness. High bosses are more susceptible to warping and shrinkage, and can also cause non-uniform cooling and blocking removal from the mold. Proper height value is required to avoid potential stress failures caused by thick regions.

Contains screw boss that fails the following conditions:

\[ \large H_b \leq T_b * R \]

\[ \begin{aligned} & \small H_b - \text{analyzed boss height} \\ & \small T_b - \text{analyzed boss thickness} \\ & \small R - \text{maximum boss height to thickness ratio} \\ \end{aligned} \]
