Automated laser punching: faster, more functional, more precise

Our automated laser punching center ensures maximum throughput. Processing continues immediately: the raw material high-bay warehouse, the sheetmaster for loading and unloading, and tool storage are directly connected to the equipment.

We machine the following materials:

  • Decapitated steel sheets 0.5 to 2.0 mm
  • Aluminium 0.5 to 3.0 mm
  • Stainless steel sheets 0.5 to 2.0 mm
  • other non-ferrous metals - on request
  • Pre-coated sheets - on request

Benefit from the advantages of our laser punching centres: Combination technologies, new punching methods and the associated process and part optimisation ensure high efficiency, minimised material consumption and low costs. The operation runs in three shifts - one of which is completely automatic.

Tiefschwarze Lasermarkierungen: präzise, permanent, abriebfest.

Smarte Gehäuse bereiten moderner Medizintechnik eine glänzende Zukunft.

Mit dem neuen Ultrakurzpulslaser eröffnen sich Ihnen, gerade in der Medizintechnik neue interessante Möglichkeiten der perfekten Lasermarkierung auf Metallen aller Art, die wir auf unseren neuesten Feinblechlösungen für Geräte namhafter Hersteller mit hervorragenden Vorteilen anbringen:

  • für fast jedes Material

  • auch auf lackierten Oberflächen

  • extrem resistent gegen abrasive, chemische und Strahlenbelastung

  • Gleicher Kontrast bei allen Lichteinfalls- und Betrachtungswinkeln

  • Idealer Ersatz für Siebdruck

  • Consecutive serial numbers possible

  • präzise und schnell

Eine satte Schwärzung der Oberfläche von Metallen erreicht man durch die Verwendung des Ultrakurzpulslasers, dem einzigartigem PERMAblack -Verfahren oder auch Dunkelmarkierung. Die mit diesem Laser erzeugten Markierungen und Beschriftungen erscheinen tief schwarz und das, im Gegensatz zu Anlassfarben, unabhängig vom Betrachtungswinkel. Werden korrosionsbeständige Teile mit dem Ultrakurzpuls Laser schwarz markiert, sog. Black Marking, ist eine anschließende Passivierung (Schutz vor Korrosion) der markierten Fläche, im Gegensatz zu einer Laserbeschriftung durch Nanosekundenlaser, nicht mehr nötig. Eine besonders interessante Anwendung ist das Dunkel- oder Schwarz-Markieren von eloxiertem Aluminium. In diesem Fall ist selbst unter einem Elektronenmikroskop keine Veränderung der Oberflächenstruktur feststellbar. Dennoch ist die Markierung oder Beschriftung tief schwarz, vom Betrachtungswinkel unabhängig und vollkommen abriebfest. Metalle, bzw. metallische Legierungen, die sich für dieses Verfahren eignen sind beispielsweise: Edelstähle, diverse medizinische Stähle, Kupfer, Edelmetalle wie Gold, eloxiertes oder unbehandeltes Aluminium, u.v.a.m. Die hohe Präzision der Laserbeschriftung oder Lasermarkierung auf alle Metalle und die dauerhafte Lesbarkeit innerhalb der Lebensdauer von Produkten, anspruchsvollsten Bedingungen und kritischen Einflussfaktoren ist besonders wichtig in den folgenden Bereichen:
