Cutting Bronze Mesh

Using Synrad lasers for cutting Bronze mesh!

   Although Bronze is a highly reflective material, we were able to cut the 0.028” thick mesh using a Synrad 240W CO2 laser and 40psi Oxygen assist gas at a speed of 7 inches per minute.  We were able to increase the cutting speed to 32 inches per minute by simply placing a 0.01” thick sheet of paper on top of the mesh. 

     The paper provides an extra layer of absorption of the wavelength, transmitting more of the laser heat into cutting power.  The spacing between the wires, rather than having a solid sheet, also aids in the absorption of the laser beam.

 

 

Marking Tires

Crisp readable marks can be created on tires with Synrad lasers! 

    Using a 125W laser, FH Marking head, and 200mm lens, the engraved marks (approximately 10mm high) were created at a speed of 25 inches per second using a resolution of 250dpi, with a cycle time of 4.7 seconds.  The same quality of marks can be achieved at a speed of 5 inches per second using 25W of power and a cycle time of 16.6 seconds. 

   The advantage of a laser over molded characters is obvious. Part-to-part flexibility, barcoding, serializing, and customization capabilities can be made without the need to re-tool.

 

 

Marking Saw Blades

Codes created on stainless steel saw blades using Synrad lasers!

   The readable contrasting marks on the saw blade, in the photo above, were created using a Synrad 125W laser at a speed of 4.5 inches per second with a resolution of 425 dpi.  The matrix code has a cycle time of 5.7 seconds, the barcode has a cycle time of 18.9 seconds, and the filled text has a cycle time of 47.8 seconds. 

   While engraved marks on thin metal could potentially weaken the strength of the material, these permanent contrasting marks were created on the surface of the blade leaving the strength of the material unaffected.
