Flagship Product
Foil Sheet Shape
Measuring Instrument
4th generation non-contact laser measurement system for detecting wavy edges on metallic foils and separators used in lithium-ion battery production.
The laser sensor performs equidistant sampling across the entire stroke, compares deviation against a reference line, and automatically determines pass/fail status.

Online Profile
Measuring Instrument
Installed on foil forming, slitting, carbon coating, or coating machines for real-time profile measurement during continuous production. Multiple laser displacement sensors scan perpendicular to the tape running direction.
Can link with production equipment to trigger alarms or shutdowns, reducing scrap from profile defects such as wrinkling, diagonal lines, edge collapse, and wavy edges.
