During the inspection process, Precision Strip has the ability to stencil, or mark those areas of a coil that are defective. Material is marked with a black ink stencil placed in the center of the strip close to where the defect is located. Some examples of defects include lamination, floppers, gouges, and holes. The stencil lists the owner from which the coil came as well as the coil identification. When the end user is processing the coil, a camera is used that detects the stencil, which triggers the operator to reject the defective area.
Stenciling is a cost effective solution to deal with defects in material. Because the coil is not broken down into multiple parts due to defects, there is a higher yield per coil. The customer receives both larger, and fewer coils. The number of coils unloaded and stored is reduced. Fewer coils loaded on the end user’s line saves head and tail scrap and reduces downtime. In addition, transportation costs can be saved.
Material identification stencil can be customized to include coil number, heat number, material type, and footage markers. This enables the customers to maintain identification throughout their process.
