The European Union and Wallonia invest in your future.
Walloon research centre for the study of
assembly technology and material testing
Service centre to the industry performing studies and applied research, founded in 1989.
Two main divisions :
Assembly & Material testing :
welding, brazing, mechanical joining and mixed joints (WPS, WPQR, WQ)
destructive and non-destructive testing (acc. ISO 17025)
Industrial Hydraulics and Hydromechanics
Target : mainly SME’s (comparable size and culture)
Multiple disciplines and flexibility : synergy between divisions
Support and management during all project phases
Feasibility studies, simulations, design, prototyping, pre-series …
