Case Study
Mold & Die Case Study 12 / 15Optical molds are used to manufacture components that control, reflect, or transmit light.
Case Overview
Customer Background
This project comes from a Optical / Precision Mold & Die manufacturing requirement for Lens / Light Guide Plate / Display Components / Automotive Lighting. The buyer needed stable machining quality, repeatable inspection results and a machine configuration suitable for real production rather than a one-time sample.
Machine Selection
HYR-CNC selected the machine plan around part size, material, tolerance, surface finish, tool capacity and expected production volume. The recommended setup focuses on rigidity, spindle stability, fixture access, tool change efficiency and inspection control.
