Plating Services
We offer a high-quality plating service to finish your castings. As with all our services, plating is done on-site to ensure utmost quality and minimal lead times for your items. Choose from gold or rhodium plating on most metals to create a luxurious edge to silver jewellery or a bright white finish on white gold.
HIGH QUALITY AS STANDARD
On-site precious metal alloying allows us to offer high quality as standard, such as 18k white gold with a high palladium content for a brighter, whiter finish.
Hallmarking with our On-Site Assay Office
Since 2013, Merrell Casting has operated with an on-site Sub-Office of the Birmingham Assay Office to offer hallmarking services, authorised by the British Hallmarking Council. This benefits our customers’ lead times, reduces the movement of precious metal to different facilities and allows us to store Maker’s Marks for the many brands and designers we work with.
