Method for molding vitreous optical elements |
摘要 |
A method for molding optical glass elements including the steps of injecting molten glass material into a mold cavity through an injection port, runner and gate; cooling molten glass material in the mold cavity to a solidified state; and applying vibrations to solidified glass material in the mold cavity through a gate-forming member inserted into the mold assembly to form a gate to make a gate cut by concentration of stresses at boundary regions between the gate and the mold cavity.
