Expertise

Test technology & laboratory

BUTTING relies on quality assurance with modern testing methods – both destructive and non-destructive – and thus guarantees consistently high product quality.

Always a leader

Quality inspection at BUTTING

BUTTING is a pioneer in quality inspection and the documentation of production results. The use of innovative X-ray technology was already routine for us in 1962, and we have been monitoring and documenting our entire production process since 1988 in order to guarantee long term traceability of every product.

Safety now and in the future

At BUTTING, we invest sustainably and permanently in quality assurance, particularly in the optimisation of our in-house testing. Through the consistent certification and accreditation of our various testing procedures, we also emphatically ensure and prove the consistently high quality and reliability of our products and services.

Extensive testing technology

Accredited laboratory

The quality management system at BUTTING is certified in accordance with DIN EN ISO 9001. Our in-house laboratory with its modern equipment is accredited according to DIN EN ISO/IEC 17025. Based on this standard, we carry out laboratory activities independently and fulfil the requirements for competence, impartiality and uniform working methods of laboratories.

Partner for innovative solutions

Hillger NDT

With Hillger NDT GmbH, which we integrated into the BUTTING Group as an independent company in 2019, we were able to gain the expertise of a renowned partner for innovative solutions and testing tasks in the field of non-destructive testing. Since then, Hillger has been supporting our internal specialists in all areas of research and development.

Hillger NDT GmbH develops and sells ultrasonic imaging inspection systems as an upstream development unit for the production and quality assurance at BUTTING. One focus is on aerospace technology. Thanks to the innovative strength of this partner, we are constantly expanding our outstanding quality assurance with additional non-destructive testing methods.
