Surface quality analysis
U ntil now, the devices available on the market have been able to measure the diameter and detect geometrical defects of wires and cables, in the drawing, or extrusion processes. However, there was a lack of a device capable of measuring defects that can appear on the surface of a wire/cable during the manufacturing process, such as a lack of plating, scratches, or defects like impurities, bubbles or particles on the insulation.
High resolution cameras are limited to large diameters and low speeds. Until now, to analyze surface defects during production, one had to take a sample off the line and examinate it under a microscope. Our SQM allows "live" action, and therefore a faster correction of defects !
The SQM : our laser surface measurement
The SQM is a truly innovative, patented instrument, developped following insitent customer demand, to continuously check the surface quality of fine wires in-line.
It works like a ring camera, all around the circumference of the wire. The image is analyzed in real-time by powerful algorithms in order to provide all necessary information about defects, such as their surface, perimeter and localisation. Alarms can be generated according to the customer's requirements.
Our surface inspection system : a success with our customers
Numerous tests carried out on customers' applications have proven the SQM's capability and performance on fine wires. Used in combination with our LPS gauge for geometry defects like lump and neckdonw, the SQM will generate a complet image of the wire surface in order to detect any defect, shape disturbances, scratches, or platting missing. A real step forward in your quality process!
Like all other CERSA instruments, the SQM is a non-contact measurment system, and is wire vibration measurement independent. It completes our line of dimensional measurement sensors on production lines.
