SYNRAD's sealed CO₂ lasers are used in a variety of industrial processes including cutting, welding, drilling, and marking. This news brief showcases some of the interesting materials and products that are processed daily by Synrad's line of CO₂ lasers and marking heads.

Marking Lacquered Aluminum

    Sealed CO2 lasers are useful in a wide range of applications in the packaging industry. The lacquered aluminum cap in the photo on the left was marked using a Synrad 25W sealed CO2 laser and FH Series Marking Head. The cap provided clean contrasting marks using 22W of power at 35 inches per second. Focusing was through a 125mm lens that provided a 180-micron spot, with a 3mm depth of focus. The seven-character mark, 0.085 inches high, was marked in a cycle time of 0.14 seconds.

Cutting Stainless Steel

   This 5/8-inch diameter stainless steel tubing was cut using 240 watts of laser power. The thin-wall (0.16") material exhibited clean cuts with a slight amount of dross. A rotary stage turned the tubing at 150 RPM while a gas jet manifold holding a 2.5” positive meniscus lens focused the beam and provided oxygen at 45 PSI to assist the cutting process. Each cut required approximately two seconds to complete.

Cutting Foam Blocks

  This 2.125-inch tall foam block exhibited clean cuts after being laser cut at a speed of 20 inches per minute. A 7.5-inch plano convex lens directed the 240W beam through the high-density foam. Spot size was 0.012”, and depth of focus was only 0.54”. Nitrogen at 30-PSI provided the gas assist.
