Ascott Analytical secures first patentTamworth-based Ascott Analytical ( has secured its first patent for the testing equipment that it supplies to the world’s leading automotive and aerospace companies.

It has spent several years developing Mag-Drive — a magnetic drive that powers the salt spray applicator in its range of corrosion test chambers — and two years after its application, the patent has been granted.

The company has made corrosion test chambers for major automotive manufacturers — including Jaguar Land Rover, Tesla, BMW, Volvo and Bentley Motors — for aerospace giants such as Boeing, Airbus, Safran and BAE Systems, and for airlines such as Lufthansa.

Ascott’s patented Mag-Drive followed the development of stringent standards by Volvo, Ford and Scania.

Corrosion tests require salt spray to be applied to components for prolonged periods to test their resistance; the new demanding protocols require the salt spray to be administered from above in a swaying motion.

Actuating a spray bar would require an access hole for the drive shaft, and because the salt spray is very corrosive, the Ascott team sought another solution.

The Mag-drive shaft is actuated entirely by rare-earth magnets sitting either side of the fibreglass shell and providing the required oscillation.

Managing director Adrian Wain, said: “We’re absolutely delighted to have been granted this patent. It is further proof that we are continually pushing the boundaries of British manufacturing here at Ascott.”

Be seen in all the right places!
