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. Wheter in the drawing, plating, 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 such as impurities, bubbles or particles on the insulation.
High resolution cameras are limited to large diameter and low speed. Until now, to analyze surface defects during production, you had to take off a sample and examinate it offline under a microscope. Our SQM allows "live" action, and therefore a faster correction of the defects !
The SQM : our laser surface measurement
The SQM is a truly innovative and patented instrument, long initiated at the customer demand, to continuously check inline the surface quality of fine wires.
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 customer's requirements.
Our surface inspection system : a success with our customers
Numerous tests performed on customers applications prove SQM capability and performances on fine wires. Used in combination with LPS gauge for geometry defects like lump and neckdonw, SQM will generate a complet image of the wire surface in order to detect any defect, shape disturbances, scratches, platting missing. A real step forward in your quality process!
Like other CERSA instruments, the SQM is a non-contact measurment system, wire vibration measurement independent. It completes our line of dimensional measurment sensors on production lines.
