Detailed Description

Describes small screw boss hole base radius issues found during injection molding design analysis.

The small screw boss hole base radius issue refers to a situation where there is sharp corners at the base of the hole in a boss. Proper base radius value is required to minimize potential defects caused by failure of the core pin.

Contains screw boss that fails the following condition:

\[ \large \frac{R_b}{T} \geq R \]

\[ \begin{aligned} & \small R_b - \text{hole base radius in analyzed boss} \\ & \small T - \text{wall thickness} \\ & \small R - \text{minimum hole base radius to wall thickness ratio} \\ \end{aligned} \]
