Deep Engraving
The photo to the right shows NLE's "Deep Engraving" process.
Depths
up to 0.030" are easily achievable, with better detail than mechanical
engraving. Most often, there is a substantial cost savings by using the
laser process. NLE can engrave both flat and curved surfaces.
The laser engraving on this item is 0.008" to 0.010" deep, and represents a cost savings of over 50% when compared to mechanical engraving!

Laser Engraving of Mold Cavities, Cores and Pins
One
of the fastest growing services offered by Northeast Laser is the engraving
of mold tooling. The level of detail obtained with the laser process
is far superior to mechanical engraving, especially for intricate artwork
or minute identification and serialization. In addition, the laser process
can often offer substantial savings over other processes since tooling
and setup are greatly simplified.
Until
recently, laser engraving was not widely recognized as a viable process
for mold and tool work, since typical depths achievable were limited
to a few thousandths of an inch. Utilizing higher power lasers, and continually
refining the process, NLE now routinely engraves up to thirty thousandths
of an inch in both ferrous and non-ferrous metals. Extremely fine work
is easily handled, since the laser spot size is less than four thousandths
of an inch in diameter.
Engraving
can be performed on both flat and curved surfaces, inside counter bores,
and in many intricate places impossible to reach via mechanical processes.
Since NLE employs Bridgeport machining bases as part of the laser workstation,
cores and cavities of up to 600 pounds are easily handled and accurately
positioned.
The
plastic-injection mold core to the right was engraved with greater detail
than could be possible with mechanical engraving. Mold core engraving
is one of the fastest growing services that NLE offers!
