The fundamental principle that underpins everything we do.

Quality is part of everyday life – Inspection / Assurance / Prevention / Optimisation. As you would expect, all our sites are fully accredited to ISO/TS 16949 – the international standard relating to the design, development and production of automotive related products.

LPSplus, the LEONI Productivity System, is an integrated suite of tools used worldwide in our manufacturing facilities, development departments and business support areas to drive continuous improvement throughout our business. All LEONI employees contribute to the achievement of our company targets. Employees work in teams and are empowered to take responsibility for their own work.

Customer satisfaction is the ultimate proof of effective performance – this is evidenced by the numerous prestigious supplier awards received from major customers worldwide.

Product quality verification

Product quality is ensured through attention to detail – a combination of effective processes and state-of-the-art equipment.

Comprehensive test systems are an integral part of our production lines – checking for presence, fit and functionality.

Our test systems incorporate vision systems and provide a flexible approach to ensuring the product performs to specification and everything is as it should be. In additional to electrical and dimensional tests typical functionality built into our test systems might include – leak tests, colour tests and push-back tests. Specialised test systems and bespoke test procedures are in place for HV (high voltage) products.

Attention to detail. Product quality. Reliability.
