Sheldon Precision Engineering Ltd is a North Devon-based subcontract CNC machining company specialising in precision-turned parts for clients across the UK. The business has developed a strong reputation for combining advanced technology with rigorous quality control, delivering high-tolerance components to industries where accuracy and reliability are critical.
“For me, precision engineering has always been about problem-solving,” explains Managing Director Howard Sheldon. “It’s not just about producing a part, it’s about giving customers confidence that what we deliver will work first time, every time.”
Company History
Founded in 2014 by Howard Sheldon, the company was established with a clear mission: to provide customers with high-quality machined parts supported by a dependable and transparent service. Although a relatively young business compared to some competitors, Sheldon Precision quickly distinguished itself by investing heavily in modern machinery, digital quality assurance systems, and a customer-first approach.
The company holds ISO 9001:2015 UKAS accreditation, ensuring that every stage of its operations—from quoting to order fulfilment—follows strict standards of traceability and reliability. This accreditation, supported by the use of the FitFactory MRP system, allows the business to offer complete visibility across quotations, work orders, invoices, and management reporting.
“When I started Sheldon Precision, my goal was simple: to create a company that clients could trust,” Howard adds. “That’s why quality and reliability are the foundations of everything we do.”
