Keep molded blind holes short enough that the supporting core pin stays stiff
Rule Card¶
| Field | Value |
|---|---|
| Pack | G_BASELINE — DFM Baseline Codex |
| Title | Keep molded blind holes short enough that the supporting core pin stays stiff |
| Severity | major |
| Check logic | Deterministic |
| Applies to | CAD hole feature |
| Inputs required | hole_depth, hole_diameter |
| Fix template | Shorten the blind hole, convert it to a through feature, or redesign the local geometry so the core pin is not forced into a high-deflection aspect ratio. |
Short Description¶
A long unsupported core pin bends under melt pressure, so deep blind holes become a tooling stiffness problem before they become a feature convenience. Through holes are much easier to hold straight than blind ones.
When It Applies¶
This rule belongs to G_BASELINE (Shared across multiple manufacturing routes) and targets CAD hole feature.
