Where You Should Find laser etching toronto

Laser etching produces a visible etching or depression into the material. Laser etching replaces traditional process like mechanical press or pin scribing. Laser etching can be done with either a Co2 or YAG laser on virtually any material surface and to any depth from very light etching to very deep etching For example, laser etching is used to engrave serial numbers into metal gun frames. Generally speaking with laser etching the material being laser etched is vaporized at the laser etching point due to the typically high power densities of the laser beam at the point of laser etching

Laser etching and laser marking generally do not produce any color changes and create a colorless impression. There are exceptions as certain plastics will sometimes react to and change color under either Co2 or YAG laser light. Also, in some cases, additives can be incorporate into the materials being laser marked or laser etched in order to produce a color change. Another exception occurs when the wavelength of either the Co2 or YAG laser is changed from those typically used in laser etching and laser marking. This can produce a color change after laser etching on some materials.

Laser annealing is another popular form of laser marking. This type of laser marking is generally undertaken with a YAG laser on metal surfaces using lower power, high frequency and slow writing speeds to produce heat on the surface of the product. Laser annealing can be used to replace electro chemical etching and ink marking as the laser annealing process creates a black mark with no etching Care must be used, as the heat generated can cause iron in some metals to be pulled to the surface, and rust can result if the parts are subjected to sterilization after laser annealing.

Moreover, you will find that laser engraving has been very much existed since in the early sixties. Another name of this particular process is laser etching. For this particular process, you will need no masks or chemicals unlike the conventional etching. You will find that the process will be really simpler and easy using the laser. If you look at the overall history, the laser engraving supplies were first used in around the 1960's. At that time, the laser was expected to be able to engrave at the least diamonds and types of metals.
