Aluminum Mould Restoration
Moulds are hollowed-out blocks that are used as tools for the mass production of parts such as plastic bottles and automotive parts. These moulds are expensive to manufacture and are therefore designed to have a long service life. Manufacturing industries thus seek cost-effective processes to maintain and repair moulds damaged in service.
Wits researchers have developed a cold spray advanced technology that restores mechanical damages, removes and repair corroded surfaces, and can add material as a 3D metal printing alternative, offering a solution to the challenges encountered in the moulding industry.
