Siemens DPM
For closed applications with a focus on checking the marking quality, Siemens DPM
verification is the best choice. Siemens DPM verification can be configured very flexibly to be
able to test markings applied with a variety of marking methods on different materials.
The quality characteristics to be checked can be selected individually. In addition to this, a
separate quality evaluation (good/fair/poor) can be set for each selected quality
characteristic to give priority to certain characteristics. When combined with a flexible lighting
setting, the quality monitoring with Siemens DPM can also solve applications that are too
restrictive or simply unsuitable for the public standards.
Measuring the marking
Each marking is measured based on the quality values and assigned a quality grade.
Deviations in the quality grade can usually be attributed to the following causes:
● Changed marking parameters or errors in the marking device
● Changed material concepts or surface structure
● Parts incorrectly secured or traced
● Changes in a disturbed environment such as oil or light on the part
● Incorrect securing or tracing of parts
Provided with the data of the verifier, the production line remains operational because
necessary maintenance or modifications to improve the marking can be performed before
the markings become unreadable. The reader provides excellent and robust functions for
direct part marking verification.
