Metal casting is a casting process in which a copper liquid is injected into a mould with a melting point higher than that of copper alloy for casting processing. The following copper fittings are suitable for metal casting:
Complex shaped copper fittings: metal casting produces various moulds, which are used to produce copper fittings with complex geometrical shapes.
Suitable for mass production: As the metal casting moulds are divided into a one-time and permanent, permanent moulds suitable for mass production of copper fittings, improve the utilization rate, cost savings.
Wear-resistant and corrosion-resistant copper fittings: copper and its alloys have excellent wear-resistant properties, suitable for high-load applications, copper has good resistance to many corrosive media, making it good performance in harsh environments.
For example: copper bushings, copper nuts, copper worm gears, copper tiles and other copper fittings.

Summary
The metal casting process offers the advantages of design flexibility, high material utilisation and suitability for high volume production when producing copper fittings. However, it also faces challenges such as high mould costs, problems with surface quality and inherent defects, and post-processing requirements. These advantages and disadvantages need to be considered when selecting a casting process to ensure that copper fittings are produced to meet requirements.
