GMP-54-7S
High Precision Optical Glass Molding GMP Machine
The GMP Series is a high-precision optical glass molding press machine designed for molding small to large diameter lenses, including diameters up to 150 mm depending on the model. It supports both die-molding fix and transfer systems, with infrared heating up to 800°C, AC servo press control, load cell force detection, and controlled cooling for stable molding quality. Optional automatic loading is available on select models to support efficient production of glass materials and molded optical parts.

Innovative reduction of optical element production processes
This molding process innovatively reduces traditional grinding and polishing processes.
Innovative reduction of optical element production processes
Selection is possible between a die-molding fix system and die-molding transfer system, which is based on customer production process.
High reproductivity realizes high quality
Uniform and high speed heating is realized via the infrared lamp. This machine excels at reproducing the molding conditions, and provides stable quality among molded parts.
