Abstract
Description
Technical Field
[0001] The invention relates to a glass blank casting machine and belongs to the field of die casting equipment. Background Art
[0002] The rough material of crystal glass beads is made by heating glass rods and then die-casting them through molds. The die-casting machines on the market are still based on the design and principle of 20 years ago. They mainly use gas and oxygen to heat the glass rods.
