AUTOMATIC POURING DEVICE AND POURING METHOD FOR LENS MONOMER
20210078270 · 2021-03-18 · ·

The present invention provides an automatic casting device for a lens monomer and a process thereof. When the lens monomer within a mold cavity reaches a liquid level monitoring point P, the cavity is exactly 50% filled with the lens monomer. The remaining of the casting process will be precisely controlled based on the obtained data from the past process to ensure an exact 100% monomer filling into the cavity.
