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
This casting methode is a versatile and widely used manufacturing process that allows for the creation of exceptionally complex or detailed castings. This method involves shaping a mold from a mixture of sand and a binding agent, which can be easily formed to replicate intricate designs. One of the key advantages of sand casting is its ability to accommodate nearly any metal alloy, including aluminum, iron, bronze, and steel, making it suitable for a broad range of applications.
The process begins with the creation of a pattern, which is a replica of the final product. Once the pattern is placed in the sand mold, molten metal is poured into the cavity formed by the pattern. After cooling, the sand mold is broken away to reveal the casting. This method not only allows for complex geometries but also supports the production of large components, making it ideal for industries such as automotive, aerospace, and heavy machinery.
Additionally, this is cost-effective for both small and large production runs, as it requires minimal setup time and can be easily scaled. The flexibility in design and material selection, combined with its capability to produce high-quality castings with excellent surface finishes, makes sand casting a preferred choice for manufacturers seeking reliable and efficient solutions.
