What is precision optical mold parts?
Optical mold refer to key precision mold components used in the molding process of optical components (such as lenses, prisms, light guide plates, etc.) to ensure high precision, high surface quality, and optical performance of products.
Characteristics of precision machining for optical mold components:
● Ultra-high precision
● Mirror-grade surface
● Long life & stability
What are the commonly used materials of precision machining for optical mold components？
High hardness and high wear resistance steels such as S136、P20 or 45# steel ect . These materials can achieve a hardness of 50-52HRC after heat treatment to meet the high-precision and long-life requirements of molds.

What are the processing of precision machining for optical mold components?
First, the appropriate processing plan and materials will be determined according to the drawings. The main processing links include:
● CNC processing: complete the initial molding, accurately shape the basic contour of the parts, and control the basic dimensional accuracy.
● Wire cutting: for complex shapes or fine structures, high-precision cutting is achieved through electrode wire discharge.
● Grinding: improve surface flatness and dimensional accuracy, reduce roughness, ensure the parallelism of related surfaces, etc.
● Mirror EDM: use precision EDM to make the mold molding surface high smoothness, laying the foundation for the mirror effect.
● JG (coordinate grinding): focus on the processing of high-precision holes, grooves and other structures to ensure that the tolerances of key positions meet the standards.
● Ultra-precision machining: for high-end optical parts, ultra-precision turning or grinding is used to achieve extremely high precision and smoothness.
Finally, polishing treatment is carried out. The surface is meticulously ground with special tools to remove micro-defects and ultimately achieve a mirror-like effect, meeting the strict requirements of optical molds for surface quality.
