Lens molding requires decentering, appearance accuracy and thinning.
Sumitomo molding machines support molding the foremost lens products with the following features:
・Keeping parallelism of platens by Thermal Free Platen
・Optimal design for optical molding with Screw assembly for lens
・Achieving thinner lenses by High precise ejector compression
・Preventing misalignment and galling by Nozzle touch force
