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.
Applications
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.
