The use of coated glass has raised significantly in many applications. This is why perfect coating and highest glass quality are a must to maintain the competitive edge. Here the newly developed, fully automated optical inspection system POWERSCAN-COATING helps. It provides operators with an easy, efficient and economic set-up for excellent defect detection and exact classification of coating and other irregularities in the surface over the entire glass sheet. The increase in processing efficiency and quality is achieved by applying the completely new, patented multi-dimension, multi-mode and multi-view technology. A 100% in-line inspection can be guaranteed for coating, color, surface, edge and shape - all at the same time, even in mixed batches. All typical coating defects, also smallest color variations for all coating types are detected as well as inclusions of all types and other surface defects. In addition the coating is checked for inhomogeneity and color flow. The system classifies and categorizes all defects and makes a distinction of removable contaminations in the products possible. This helps to react and adjust quickly during the manufacturing process. The overall result: highest quality and maximum productivity with minimized production costs.
