Sand casting
Alteams delivers sandcasting solution, ideal for custom designs, low volume aluminium parts and complex geometries. At Alteams, it is possible to produce aluminium castings with pouring weights up to 600 kg and mould weights up to 5 tons.
What is Sand casting?
Sand Casting is a manufacturing process used to make metal parts by pouring molten metal into a mould made of sand. It’s one of the oldest and most versatile casting methods.
In sand casting, a mould is created by packing sand around a pattern of the part to be made. The molten aluminium is then poured into the mould cavity. Once the metal solidifies, the sand mould is broken apart to remove the casting. The part is then cleaned and inspected.
When is Sand casting used?
- Medium-volume production → Ideal when quantities are smaller, or tooling cost must be low.
- Large or heavy parts → Can handle sizes that die casting cannot.
- Complex shapes → Works for geometries that are difficult to produce with die casting.
Why is Sand casting used?
- Very versatile → Can produce almost any shape or size.
- Low-cost tooling → Patterns cost less than steel dies, so the upfront investment is lower, making them more economical for short production runs.
- Good for complex or heavy parts → Can create shapes that other casting methods struggle with.
- Flexible production → Useful for prototypes, one-off parts, or very large industrial components.
Where is Sand casting being used?
- Automotive: large engine blocks, cylinder heads, housings → low-volume, complex shapes, flexible in alloy choice.
- Industrial Machinery: pump bodies, valve bodies, gearbox housings → robust, heavy, and able to handle large geometries.
- Energy / Power Generation: turbine casings, boiler parts, generator housings → large, heat-resistant, and customizable.
- Marine / Shipbuilding: propeller hubs, rudder stocks, engine housings → corrosion-resistant alloys, large-scale parts.
