Why Your CAD Lies to You
Walls look fine in CAD — and warp in the mold. Draft looks adequate — and the part galls on ejection. Our reviews are built on 41 years of real failure data from the floor, not theory. Here's what we catch, and what it costs if you don't:
| Error Type | Typical Cost After Tooling | With Pre-Tooling Review |
|---|---|---|
| Wall thickness issues | $25,000–$75,000 — Major tool rework or re-cut | Caught in review |
| Draft angle errors | $15,000–$50,000 — Ejection damage, surface defects | Caught in review |
| Gate location problems | $10,000–$30,000 — Visible flow marks, weld lines | Caught in review |
| Undercut design | $20,000–$60,000 — Additional slides or lifters needed | Caught in review |
| Rib/boss proportions | $15,000–$40,000 — Sink marks, structural failure | Caught in review |
