Plastic Injection Molds

Young Optics’has a comprehensive system of high precision equipment, including five-axis free-form ultra-precision processing machine, high precision CNC cylindrical grinder, jig grinder, vertical combined finishing machines, electric discharge machines, and ultra-precision co-ordinate measuring machines, to ensure the precision of the jigs/molds meet the quality specification required for key steps in the manufacturing processes. In addition to standard aspherical lenses, the company is also capable of carrying out research and development for micro-lens arrays, diffraction components, free form lens molds. All these have been successfully applied to VR/AR Glass lens and HUD Combiner/Mirror and other optical products.
