GSM Series (Soda Lime-Molded) High Quality solid Glass spheres.
Made from superior quality raw material (Soda Lime).
Produced using state of the art Molding technology.
This process enables a targeted and exact forming of glass beads, especially with diameters > 4.0mm. This type of production is quite labor intensive, but allows for production of beads with excellent roundness in a size range up to 25mm.Advantages
-
high degree of purity
-
low proportion of air bubbles
-
smooth and shiny surface
-
Very high roundness
