Metal is a substance that is widely present in nature and is rich in properties such as ductility, electrical conductivity, and thermal conductivity. It is widely used in life. Metal surface defect detection is an effective way to optimize the quality of metal products, providing quality monitoring at all stages of production to ensure production stability.

The surface inspection system can detect cold-rolled steel, color-coated steel plate, copper foil, aluminum foil, stainless steel and other materials, and can be deployed in multiple production links such as cold rolling, annealing, coating, testing, and slitting. Common surface defects of metals include pinholes, peeling, wrinkling, oil stains, bumps, etc. Among them, "pinhole" defects are small in size, fast in production line, and require high detection accuracy, making identification difficult. Many technologies of the company's detection system are advanced. First of all, the smart camera has patented technology, which has high detection accuracy and meets the detection needs. Secondly, the "pinhole" detection mostly adopts the "transmission" lighting method. The company's high-brightness and patented technology LED light source can ensure the light efficiency. The "Bi-Level" light source technology can more clearly and accurately reflect the true appearance of material defects and detect subtle optical distortions. Supported by a number of technologies, to achieve accurate detection of "pinhole" defects.

In addition, the system can also help users to choose the best slitting scheme, automatically rank sub-rolls, remove imperfect parts, and ensure the quality of customer shipments.
