With over 40,000 employees in 100 countries, Danfoss is a leading Danish multinational company specialising in heating, cooling, and machinery products.
Faced with complex part marking challenges, Danfoss was looking for innovative solutions for:
They ended up choosing the 2D Data Matrix codes marking method. Gravotech's experts led them to adopt a laser marking system with workstations – revolutionizing their working methods in the process.
In 5 years, the Danfoss x Gravotech collaboration has made it possible to fully automate the production line:
“It was actually using the laser that sparked the idea of automating the rest of the production line with robotic arms.”
Thanks to the partnership with Gravotech, Danfoss streamlined operations, consolidating permanent marking, assembly, testing and packaging into a single optimised part marking process.
With lead times reduced from four days to one, Danfoss can now quality mark over 1.2 million valves per year.
This collaboration allowed the company to cut down operational times, saving no less than 2,800 hours per laser – – which amounts to approximatively 4 months of work!
Danfoss’s eight lasers can operate 18 hours a day, marking 1,200 parts daily. A single operator can now process up to 10 valves simultaneously, total marking each batch within just 45 minutes.
