pump head manufacturers with high precision transparent glass ball 3mm4mm5mm glass beads Glass beads production line is the use of the principle of flame floating method, the glass is broken into a certain size of particles, and in a certain way to send glass particles into the flame, under the action of the flame, glass particles softening, melting, beading, cooling and solidification become glass beads. The appearance of glass beads is clean, transparent, without obvious air bubbles and impurities.
