1. All standard and special sizes are available with drawing 2. ISO 2000 quality control 3. Strong engineering team makes high
We produce the casting production according to the drawing or samples from our customers, including kind of material. Such as SUS304, SUS316, SUS201, SUS202 and so on. Below it is the tolerance list.
1. Linear tolerance
casting basic size (mm) | ≤10 | 10~25 | 25-50 | 50-75 | 75-100 | 100-150 | ≥150 |
General tolerance (mm) | ±0.15 | ±0.25 | ±0.40 | ±0.50 | ±0.70 | ±1.0 | ±1.0 |
Special tolerance (mm) | ±0.10 | ±0.15 | ±0.25 | ±0.40 | ±0.50 | ±0.65 | ±0.8 |
2. Flatness straightness roundness tolerance
casting basic size (mm) | 0~25 | 25~50 | 50~75 | 75~100 |
General tolerance (mm) | 0.2 | 0.4 | 0.6 | 0.8 |
3. The limited size of core hole
item | Aperture range (mm) | L/D |
Blind hole (deep * aperture D) | 2~3 | ≤1 |
4~7 | ≤2 | |
≥8 | ≤2.5 | |
The through-hole (long L* aperture D) | 2~3 | ≤2 |
4~7 | ≤4 | |
≥8 | ≤5 |
4. The range of casting size and casting weight
item | max | min | best |
Overall dimensions | 400*300*300 | 10*10*10 | 200*100*100 |
weight | 50 | 0.005 | 0.2000~2.000 |
