Material Shrinkage Data
Plastic Resin Injection Tolerances
Our scientific molding parameters adjust directly for material shrinkage variations across resin types. Standard draft angles of 1° to 2° are required for smooth part ejection.
| Resin Classification | Common Materials | Linear Tolerance |
|---|---|---|
| Low-Shrinkage Resins | ABS, PC, PMMA | ±0.05 mm to ±0.10 mm |
| High-Shrinkage Resins | POM, PP, PA66 | ±0.12 mm to ±0.20 mm |
