Title:
INDUCTION HEATING MOLDING APPARATUS
Document Type and Number:
Japanese Patent JP2005179084
Kind Code:
A
Abstract:
To provide an induction heating molding apparatus in which more rapid and efficient temperature control can be performed by heating focused on molding parts of molds brought into contact with an optical element material for heat-molding an optical element product.
The induction heating molding apparatus melts and press-molds the optical element material by induction heating an upper mold and a lower mold used opposite to each other by using a magnetic flux generated by a common induction coil, wherein a first heater heats the upper mold with a first heat quantity by the flux, and a second heater heats the lower mold with a second heat quantity larger than the first heat quantity by the flux.
