Reject rates measurably reduced
CAD-PRO laser projection systems from LAP enable the company Cotesa to avoid errors during composite manufacturing processes and thus to significantly reduce reject rates. The precision of these laser systems also helps Cotesa meet the high quality standards expected by the aviation industry.
Cotesa is a manufacturer of composite fiber components, especially for the aviation industry, and has around 400 employees and 3 sites across Germany and China. At the site in Mochau near Dresden, where fuselage components are manufactured for the Airbus supply chain, all workstations in the laminates area are equipped with LAP's CAD-PRO laser projection systems. Since rolling out the laser system in the laminates area, Cotesa has enjoyed many of the advantages of laser technology. Errors are prevented and reject rates significantly reduced. And this pays off in monetary terms.
Reproducible quality – every day
“The major advantage of this system is that it enables us to keep quality at the same high level,” explains Christian Bartsch, CEO of the Cotesa Group. “The laser system indicates the exact positions of the pre-cut prepregs. This means that the pre-cut parts can be accurately aligned with the right edges – every time, every day, and always in the same positions. Ultimately this guarantees the precision that we rely on to meet the aviation industry’s high quality standards.“
Calculable cost savings, optimized laying times
“Errors simply can’t happen. This is the key effect, and it can be quantified. Using this system has significantly reduced reject rates, and that’s a calculable cash saving, according to Christian Bartsch. It also saves time. The laser projection system is linked with Cotesa’s ERP system, which means the laying times for the different layers can be tracked. This offers still more potential for optimization.
Along with the measurable effects, the CEO mentions another advantage: “We have enjoyed an exceptional partnership with LAP for many years. Whenever we have questions or need technical support, we only have a short way to go. That’s why we have never regretted choosing the LAP system.”
