The Royal Mint is to manufacture up to 4,000 medical visors per day to help protect NHS staff from coronavirus.
Engineers developed a successful prototype in 48 hours and the first visors are already in use at a hospital in Wales.
Since news of the visor production emerged, the Royal Mint has received requests to supply hospitals across the UK.
Production is now moving to 24 hours a day, seven days a week at the Royal Mint’s site in Llantrisant, south Wales.
