Laser engraving is the preferred technique when attaching metal pins. Since laser-printed images cannot be easily removed, they become an integral part of engraved promotional pens, so that your company name is not easily forgotten.
Unlike other crisp, tight and detailed engraving technologies, laser engraving does not contain any tools that come into contact with the marking surface and wear out over time. In contrast, laser engraving uses a laser to engrave or mark an image onto the substrate.

Although this method is technically complex, it is possible to achieve clear and precise engraving at high speeds.
This can be achieved using a laser engraving machine that has three components: a controller that regulates the speed, intensity, direction, and propagation of the laser beam; the laser the controller uses to track the image onto the media; and the engraving area or substrate.
Here's how it works:
The previously created images are uploaded to a computer and then transferred to a laser engraving machine.
Promotional executive pens are loaded onto the conveyor belt either by a robot or by hand with the engraved surface facing up.
As a conveyor belt guides the pen through the engraving area, the laser beam etches the reciprocating design like a metal inkjet printer.
There are two main modes of laser engraving: vector and raster. Vector engraving follows the lines and curves of the image to be engraved, similar to the fact that a pencil has an outline. Raster-based lasers move in a slow forward and backward-moving model using on / off pulses, similar to raster images in computer graphics.
