AI Technical Summary
In existing array mold manufacturing, hard materials are difficult to process, resulting in low processing efficiency, rapid tool wear, and difficulty in controlling mold precision, which seriously affects the forming accuracy and production cost of optical lenses.
Ultra-precision machining is performed using a mold substrate material with low hardness to form micro-nano array grooves. A high-hardness ceramic layer is then grown on the substrate surface using a crystal growth method to ensure that the ceramic layer complements the substrate array structure, thereby reducing tool wear and improving accuracy.
It achieves high-precision, low-cost array mold manufacturing, resulting in high lens forming accuracy, long mold life, improved production efficiency, and reduced costs.
