Sand casting

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
