Sand Casting
Capability bounds and precision manufacturing specifications for Sand Casting.
Capability Bounds
| Standard Tolerance | Typically +/- 1.5 mm for the first 150 mm, plus an additional +/- 0.008 mm per mm thereafter. A dedicated machining allowance of 3 mm to 6 mm is standard industry practice and should be added to all critical surfaces. |
|---|---|
| Min Feature Size | Min Wall Thickness: ~4 mm (Ferrous Metals), ~3 mm (Aluminum/Bronze Alloys). Min Draft Angle: 1.5° - 3° on all surfaces parallel to the pattern draw direction. |
