Cadbury workers are using chocolate machines to produce visors for medics who are treating coronavirus patients.

Mondelez International, the company behind the chocolatier, has joined forces with engineering company 3P Innovation to help produce thousands of visors to protect NHS staff from COVID-19, the disease caused by coronavirus.

The visors will be made using 3D printing technology normally used to make chocolate sculptures at the food manufacturer's factory in Bournville, the home of Cadbury, in the West Midlands.

Historically, Cadbury's Bournville factory stepped in to help make gas masks, jerrycans, service respirators and aeroplane parts for Spitfires and Lancaster Bombers during the Second World War.

Louise Stigant, UK managing director at Mondelez International, said: "I'm extremely proud that our research and food engineering teams have come up with a creative way to repurpose our chocolate making skills and technology, so we can make and print parts for the medical visors.

"By working in partnership with 3P and other businesses we can scale our operations and help protect those who are working so hard to protect us and beat coronavirus."

3P innovation has already delivered the first visors to a Warwickshire NHS clinic and will be scaling up its operations, with the aim of making and delivering up to 10,000 units every week.

Printing business Ricoh 3D, based in Telford, Shropshire, is also in discussion with NHS trusts across the country to produce thousands of face shields a week.

Work has already begun on making the reusable visors with 250 delivered to New Cross Hospital in Wolverhampton on Thursday.

Ricoh said that it can ramp up production to make 40,000 visors a week.

Prospect School, a secondary school in Reading, Berkshire, has also worked to produce face shields, which will be distributed to local GP surgeries and to the Royal Berkshire Hospital.

The school has also delivered goggles and protective clothing from its science department to the hospital.

Meanwhile, Toy giant Lego is making medical visors for doctors and nurses.

It said six of its moulding machines in its factory in Billund, Denmark, is producing the safety masks for Danish health authorities.

Lego said it can deliver 13,500 visors daily, which can grow to 58,000 a day within two weeks to meet growing demand.

While the operation is still in the early stages, Lego said it is considering expanding production in other factories around the world.

It comes after the British Medical Association warned doctors' lives were being put at risk by a lack of personal protective equipment, with some medics describing the current provision as "useless" in a recent survey.

The news follows the announcement by Jaguar Land Rover which commenced production of reusable visors for medical staff on April 3, with the aim to produce 1,300 each week.
