Electronics & Optics Industry Applications | Micron-Precision Circular Blades and Specialized Knives
Industry Challenges and Requirements
As the electronics, optical display, and new energy industries continue to advance toward higher precision and thinner materials, some manufacturing applications require cutting accuracy at the micron (µm) level.
In lithium battery electrode slitting, excessive metal burrs generated during the cutting process may increase the risk of separator damage and internal short circuits. Likewise, during the cutting of optical films such as polarizers and diffuser sheets, the generation of particles, burrs, or edge deformation may affect subsequent processing, optical performance, and overall product yield.
Therefore, material selection, cutting-edge quality, dimensional tolerances, and runout control are all important factors in high-precision cutting processes.
Core Application Scenarios
- Lithium Battery Electrode Slitting
Suitable for high-speed, continuous precision slitting of cathode aluminum foil, anode copper foil, and related electrode materials, helping reduce burr formation and edge defects. - Optical Display Film Cutting
Suitable for precision slitting of polarizers, diffuser sheets, prism sheets, and optical film materials such as TAC and PET. - Semiconductor and FPC Precision Die-Cutting
Applied to the precision die-cutting of flexible printed circuits (FPC), dicing tapes, and related electronic materials.
