NDC Gauging Systems Enable You to Take Control of Your Coating Quality

When applying any coating, uniformity and maintaining minimum tolerances are key to ensuring product quality and cost control. That’s why it is essential to precisely determine the coating weight online, rather than with fewer and delayed manual laboratory measurements or downstream at the next coil process.  On-line measurements also allow for direct control of the coating application.

Accurate Coating Weight and Coating Thickness Measurements
NDC’s precision Near Infrared (NIR) gauging systems effectively measure a variety of coatings and a range of weights in real-time, on both sides of the product and from edge-to-edge. Coating types measured include oil, wax, lacquer, varnish, passivation (phosphate or titanate) and anti-fingerprint coatings.  Coatings can be both wet and dry depending on type and application. For all, the on-line measurements are 10x faster than other comparable systems and unaffected by process and ambient conditions such as lighting fluctuations, temperature, relative humidity, air quality and product movement. Complete process visibility and control ensures higher production, product quality and process efficiency.

Precise Length and Speed Measurements
For controlling and monitoring the speed of products during the coating process, as well as measuring the total length of the product, NDC offers the LaserSpeed® Pro non-contact gauge. This laser-based gauge provides an accuracy of better than +/-0.03% with +/-0.02% repeatability.

If defects are detected, the accurate speed and length measurements are used to identify the location of the defect in the material being processed.

NDC’s gauging systems are proven performers at numerous mills across the globe and can be configured to your meet your unique metal coating and length and speed application needs. From initial project definition to final system implementation, our team of highly experienced and knowledgeable application specialists will support you every step of the way.
