Standard Tolerance For Preforms
Diameter Tolerance
| OD(mm) | Basic allowance(mm) | Sintering Tol.(mm) |
| > φ5-φ14 | 0.8 | ±0.2 |
| > φ14.1-φ25 | 1 | ±0.3 |
| > >φ25.1一φ48 | 1.2 | ±0.4 |
| >>φ48.1 | 1.6 | ±0.5 |
Center and Exit hole tolerance
| Hole dia (mm | Tolerance (mm) |
| >φ0.8一φ1.5 | ±0.1 |
| >φ1.6一φ3.0 | ±0.2 |
| >φ3.1一φ8.0 | 土 0.3 |
Length & Concentricity
| Basic allowance(mm) | Sintering Tol. (mm) | Concentricity |
| +(0.4+0.5%L) | ±0.5%L | <=0.3 |
| For example, if L=100mm, then it's basic allowance is +0.4+0.5%*100=0.9mm Sintering tolerance is ±0.5%*100= 100.9±0.5mm. | ||
