Wine manufacturers must ensure that the cork stoppers used to seal their products are of the highest quality. However, because they are cut from the bark of an oak tree, some corks may have imperfections such as holes or color imperfections. While effects such as holes may not be acceptable, minor imperfections in the color of a cork may be deemed acceptable. To sort these, M3C Industrial Automation and Vision has developed a line of automated systems that uses 3D imaging to inspect different types of cork stoppers and to inspect disks that are used to build cork stoppers. The system inspects these disks at up to 25,000 parts per hour.
