Bystronic glass announced it has delivered its 1000th sealing robot, a milestone since the former company Lenhardt Maschinenbau GmbH—now Bystronic Lenhardt GmbH—developed and built the first robot in 1981.

“Our long-standing customer Flachglas Wernberg (Germany) gave us the initial design suggestion for the shape of the nozzle,” recalls Heinz Burghard, who previously worked on the production of the first sealing robot.

“Employees at Flachglas Wernberg proposed to the then managing director Karl Lenhardt, to develop a round nozzle rather than an immersion one. As it turned out, this was a decisive factor in significantly improving the quality of the sealing process. The first worldwide sales of sealing robots subsequently followed.”

The latest robot, the “speed’sealer,” was sold to a Chinese customer out of Bystronic’s Neuhausen-Hamberg location. The speed’sealer can seal a triple insulating glass unit in two rounds without the need for nozzle exchange or downtime, according to a release from the company.

“The speed’sealer is one great machine,” says Burghard. “I can hardly imagine any future direction for sealing robot development. We have implemented and achieved so much. I am very proud that I was part of this story from the outset and even today, I still work on the assembly of the speed’sealer.”
