Four-Hole Button Mold Mirror Finishing

Core Technology of High-Precision Mirror Finishing

Achieving a fine mirror finish on mold surfaces requires precise control of the EDM finishing process to ensure a smooth and uniform surface appearance. NEUAR CNC EDM technology enables high-precision mirror finishing for mold applications, producing a reflective surface while maintaining the fine details and geometry of the machined cavities.

This machining case demonstrates the mirror finishing capability of NEUAR CNC EDM on a four-hole button mold, highlighting the surface quality and consistency achievable through fine finishing.
