Bunting Magnetics has appointed David Summers as its new European quality manager. He brings a wealth of experience in quality management, with exceptional attention to detail and a positive attitude that has immediately resulted in production process improvements.
Bunting Magnetics is one of the world’s leading designers and manufacturers of magnets, magnet assemblies and magnetising equipment with globally located manufacturing facilities. David Summers is a chartered member of the
Institute of Mechanical Engineers (IMechE) and a practitioner of the
www.quality.org Chartered Quality Institute (CQI). He has qualifications both in ‘Lean Six Sigma’ and management and leadership.
Since joining Bunting Magnetics in March 2025, Mr Summers has immersed himself in understanding the diverse nature of customers and the supply chain. He became involved in one particularly challenging project involving a four-pole samarium cobalt (SmCo) rotating magnetic assembly which is used in a permanent magnet motor for an aerospace application.
Complex assemblyThe construction of the complex assembly involves many aspects of the manufacturing process including grinding of magnets, grinding of containment sleeves, and tight tolerance and run-out control of bearing journals. The bearing journals have a 5µm tolerance, one of the tightest specifications in any application.
The final inspection of this critical bearing journal dimension is sub-contracted to the
QCI Group, an industry leader in specialist metrology, quality, and engineering solutions. Established over 20 years ago, it specialises in all aspects of metrology, sub-contract CMM measurement, quality inspection, re-work, and quality engineering.
When a potential measurement issue was raised by the magnet assembly customer, Mr Summers assembled a team from Bunting’s supply chain and the customer to visit QCI and review the latest methods of measuring this challenging dimension. Within just a few weeks, the customer had a new appreciation for the measurement process and capabilities of QCI, as well as an agreed inspection process that would result in reducing the inspection time and, subsequently, cost.
Mr Summers will lead the strengthened Bunting Magnetics quality team, focusing on improving processes and designs to meet the expectations of clients when purchasing magnets, magnet assemblies, and magnetising systems.
