Glass Beads

Glass bead is a unique and popular air blasting abrasive for cleaning and conditioning surfaces. It is manufactured from high-grade glass, annealed in its spherical shape to equalize internal stresses and resist fracture. In addition, the inherent strength of glass bead is such that it can survive multiple impacts, allowing for economies of continuous recycling.

Quality Assurance

At every stage of the manufacturing process, Medias submits its products to rigorous quality control: the grinding of the glass, the granulometric distribution, surface treatment, packaging, etc, Sophisticated computerised control techniques ( laser diffraction granulometer, digital image analyser, etc) guarantee that the most rigorous standards and specifications are adhered to. SOVITEC is the longest-established producer in Europe, dating back to 1954, and in 1991 became the first to be granted ISO 9002 certification.


Its application include cleaning moulds, glass carvings and decorative works in glass industry, removing rust and corrosion without disturbing the base material; blasting for cleaning and conditioning surfaces without changing their dimensional tolerances or contaminating them and shot peening aircraft parts to increase fatigue strength, reduce wear and friction and to relieve stress.
