Cutting Stainless Steel Tubing
 
This stainless steel tubing was cut using a Synrad 240W laser!

   Stainless steel tubing is normally difficult to cut without deformation, however this 0.018” thick tubing (shown in the photo on the left) was cut using a Synrad 240W laser.  Unlike traditional mechanical cutting methods, non-contact laser cutting prevents distortion or deformation of the material with the added benefit of no mechanical parts to wear out.  The photo on the right shows a close-up view of the cut edge quality.

   The 5/8” diameter tubing (with a .018" wall) was cut using 240W with 40psi Oxygen assist gas while being rotated at a speed of 241rpm.  Cut speed was 7.8 inches per second, giving a cycle time of .25 seconds.    

 

 

Marking PVC Coated Bottles
 
These codes were marked using a Synrad 10W laser.

   The PVC coated bottle in the photo above was marked using a 10W laser and FH marking head, with a 200 mm lens.  The text was marked at a speed of 25 inches per second in a cycle time of 0.27 seconds. 

   PVC marks very well with CO2 lasers.   The material generally provides a brown contrasting mark easily readable with the human eye.  1D and 2D barcodes also generate the same type of contrast on PVC and can be read by barcode vision systems in production environments.

 

 

Marking Test Tubes

A readable 2D code created on Pyrex using a Synrad 10W laser.

   Using a Synrad 10W laser, FH marking head and 125mm lens we were able to create readable 2D codes on the Pyrex test tube shown in the photo above.  The 2D Data MatrixTM code was made using 6W of power at a speed of 4 inches per second.  The mark has a cycle time of 2.8 seconds!

   For marking 2D codes on glass, WinMark Pro’s spot marking style property was set to Yes and a spot mark duration value of 0.1ms was chosen.  Resolution was set to 50 and the 2D barcode bitmap property was set to No so that each cell is comprised of a vector circle.  The overall code size is 0.235” square.
