The most cost-effective way to achieve efficient control of cutting width and coordinates to minimize waste and optimize production.

Engineered for high-speed width measurement in harsh industrial environments

Our width and shape control solutions are optical, laser and vision based sometime standalone, sometime used in combination; they represent the state of the art of non-contact width and shape control on hot and cold strips and slabs, but also on long products such as billets and pipes. The dimensional control of width and shape is of particular importance to facilitate subsequent processing by having immediate information on non-conformity and for the purposes of the waste optimizing.

Widely used during the process to determine the perfect cutting coordinates and promptly communicate them to the shears and online cutting systems. The advanced analytic software ( AAS) give access to a wide range of information which may drive the quality optimization purposes. Bar details are presented in the data tables to the right of the images.

Typical data displayed includes the Bar ID, Thickness, Optimization Criteria (i.e. customer defined strategy), overall width, cut line, cut length, cut status (to cut or not), crop area, crop weight, etc. Other parameters can also be displayed based on customer configuration details.
