What are the typical tolerances for injection molded parts?
Tolerance is one factor that is carefully considered during the injection molding process. However, there is no set tolerance range for molded items. The only factors that matter are the part size, geometric complexity, and mold design. The standard tolerance range for common molded parts is as follows:
| Parts Types | Tolerance (Inches) |
| Simple Injection Molded Parts | +/- 0.001 to 0.003 |
| Geometrically Complex Parts | +/- 0.005 to 0.01 |
| Large molded parts | +/- 0.01 to 0.02 |
