Sand casting is a very traditional and widely used casting process for copper fittings of all shapes and sizes. For copper fittings, sand casting is particularly suitable for the following situations:
Complex shapes: Sand casting is able to handle complex geometries because the sand mould is relatively flexible and can fulfil a wide range of design requirements. This makes it suitable for casting copper fittings with complex structures, such as decorative parts or mechanical parts requiring specific details.
Medium to large copper fittings: Sand casting is suitable for medium to large copper castings. Compared to other casting processes, sand casting is able to handle larger sizes of copper fittings.

Copper fittings for small series production: The sand casting process is suitable for small series production or pilot stages due to the shorter cycle time and lower costs of mould making. This is especially true for copper fittings that are produced in small quantities.
Wear- and corrosion-resistant fittings: copper alloys have good wear- and corrosion-resistant properties, and sand casting is able to produce copper fittings with these characteristics, e.g. for machinery, construction or marine applications.
Cost control: Compared to investment casting, sand casting is less costly, especially in terms of moulds and raw materials. This makes it suitable for projects that are cost-sensitive.
Overall, sand casting is a flexible and cost-effective casting method that can handle a wide range of shapes and sizes of copper fittings, and excels especially in complex shapes, medium to large castings and small production runs.
