Telesis, the world leader in direct part marking of
2-D codes, offers two different permanent
system technologies to
satisfy a wide range of applications.
Peen Markers provide an effective but extremely economical solution
to many 2-D code DPM (Direct Part Marking) applications on materials as
diverse as plastics and hardened steel. Telesis' patented
Marking Technology provides highly accurate dot placement at specific
X/Y locations. This process makes
Markers far superior to
conventional "oscillating stylus"
markers, especially in 2-D
code applications, where accurately marked codes are the key to
Markers are truly
"state-of-the-art", producing almost perfectly formed 2-D codes nearly
instantly on a wide range of materials, including virtually all
plastics and metals. These qualities make Telesis
choice for applications requiring extremely high throughput or very
small 2-D codes.
typically cost $8,000-$20,000;
markers are more commonly priced
in the $50,000-$70,000 range.
and all other
markers imprint a round dot; whereas a laser
marker is capable of marking a square cell. This adds to the relative
marks in 2-D applications, since a theoretically
perfect Data Matrix® 2-D code is based on square cells.
marker utilizes much smaller components than a
marker, making it easier and less costly to integrate.
A laser marker is almost always much faster than a
other dot peen marker. For instance, the time to imprint a 10x10 2-D
code with a
Marker is typically in the range of 2.5 - 5
seconds; with a laser it's more on the order of ½ second.
marks are widely accepted by the aerospace industry
marking critical parts;
markers are typically not. The
cross-section of a
"crater" (dot) has no sharp corners, only
gentle curves, resulting in no significant stress concentration.
marking can adversely affect material properties in the
zone of the mark, which can potentially result in the propagation of
cracks in certain materials.
marks are by nature low contrast marks, which depend solely on
illumination techniques to create the contrast required for
the other hand, in certain applications,
marks produce higher
contrast, which tends to add to their readability.
part marking of machine-readable 2-D codes provides "cradle-to-grave"
traceability, improving manufacturing efficiency, quality control, and
inventory management. In addition, it satisfies a number of
industry-specific and government mandates, including U.S. Department of
Defense UID (Unique Identification) requirements. The process involves
three key stages:
Permanent marking of the code utilizing a dot peen marker
or laser marker
Verifying the readability of the code
Reading the code at various times during the manufacture
and/or life of the part.
Telesis offers a wide range of both
systems that satisfy a wide range of 2-D code applications. In
addition, if offers expert integration of these markers in conjunction
with verification and reading equipment offered by a number of
markers and all
markers except for the
TMM5100/420 comply with all major 2-D code DPM standards, including:

Department of Defense Guide to Uniquely Identifying Items
