The Data Matrix™ Code (~.2" sq.) on this torque converter was marked using WinMark Pro's Spot tool. The code was marked with 95 watts of power at a speed of 1" per second (7.4 second cycle time).
This steel crankshaft for a diesel engine was marked with a raster-filled Data Matrix™ code (~.375" sq.) using 120 watts of power at 2.5" per second (3.75 second cycle time).
2D codes have gained popularity in the automotive industry, thanks to their ability to pack a large amount of information into a very small space. Synrad CO2 lasers are ideal for marking these codes on a wide range of materials, including mild and stainless steels. Often considered an Nd: YAG laser application, steel marking can be easily accomplished with a CO2 laser, and in some applications, as little as 50 watts is all that is required! CO2 lasers can offer users a number of benefits over YAGs, including fewer safety requirements and higher contrast on some metals. Generally, for marking applications requiring less than 100 watts of power, CO2 lasers are significantly less expensive than YAGs.
With Synrad's versatile WinMark Pro software, Data Matrix™ codes may be marked using one of two techniques: WinMark Pro's Spot tool may be selected to create codes comprised of "spots" that make up the individual cells, or raster-filled codes comprised of standard square cells may be programmed in the software. Both types of Data Matrix™ codes are easily read with a scanner.
