Sand casting
Sand casting can create exceptionally complex or detailed castings and can be used to cast nearly any metal alloy.
Benefits
- High production adaptability
- Small quantities are possible
- Large components can be made
Possible materials
- Ductile cast iron (also ADI – Austempered ductile iron)
- Grey cast iron
- (Stainless) steel
- Non-ferrous metal
Technical specifications
- The commonly used casting tolerance table for linear dimensions is CT10 according to ISO 8062 (wall thicknesses CT11)
- Weight: from 0.2 kg
- Maximum dimensions: 2,000 mm
- Casting wall thickness: ≥ 6-8 mm. Smaller is possible, depending on the structure
- Draft angle: min. ± 1.5°
- Geometric tolerances that are required for the function should be specified in the drawing
- As far as possible, use uniform wall thicknesses to achieve a uniform solidification of material. In case of different wall thicknesses, inclusions and cracks, and even porosity may result
Finishing options
- Electrolytic zinc plating
- Blasting
- KTL (Cataphoresis)
- Primer, wet painting and powder coating
- Hot-dip galvanising
