In as high-tech an area as surface engineering, it quickly became necessary for HEF to make itself known outside France so as to permit the expansion of its most innovative solutions and to put them within everyone's reach. In addition, this early and controlled worldwide development enables the HEF Group to make its considerable Research & Development efforts profitable and always to keep itself at the forefront in the resolution of tribology problems. Today, the Group is present in about twenty countries and can guarantee large accounts that the same technologies and the same levels of quality as those proposed in France or in Germany are available in its Chinese, Polish, Brazilian, American, etc. units.
