Film / Sheet
KEYENCE sensors offer solutions for a variety of process improvement and quality control challenges in the film and sheet industries. Whether the film/sheet is transparent, opaque, thick, or thin, the solutions below can help your process run more efficiently.
Measure transparent film immediately after coating using the SI Series. By traversing the sensor, you can get real-time process feedback across the width of the web to improve overall quality while minimizing waste.
Micro-head Spectral-interference Laser Displacement Meter
By monitoring the gap between coating rollers at one or both ends, it's possible to maintain tight control over sheet thickness. The LS-9000 Series can measure gaps as small as 10μm, so this solution works for even extremely thin films.
High-speed optical micrometer
2D Laser Profilers can inspect the end profile of a roll as the sheet is wound to prevent telescoping/dishing. With in-process inspection, issues like wrinkles and meandering during unwinding can be avoided, leading to overall improved efficiency.
Measure the width and thickness of rubber sheets with a single system. By using a laser profiler on each edge of the sheet, you can monitor the height difference between the roll and the material to get thickness and edge profile, in addition to sheet width.
Complete 3D inspection of belt surfaces for small irregularities or foreign matter to prevent quality issues. The WI-3000 is a 3D displacement sensor that can quantify these defects to help inform preventative maintenance decisions.
