Tolerance Guide
Automation component inspection should focus on assembly‑related features: hole patterns, datums, locating faces, mutual positions, parallelism, perpendicularity, fit and motion clearances, and interface coordinates.
Assembly‑related features are more critical than isolated dimensions and should be the inspection priority.
- Ensures consistent molding performance
- Reduces defect rate in high-volume production
- Enables interchangeability of components
- Critical for complex molds with deep cavities
- Supports high-end industry standards
