What is laser engraving and how it is done
Laser engraving is the process of engraving objects using laser. This is simply cutting and marking items using the laser system. This works just as a printer does. This takes seconds to create a permanent engraving on an object. During the laser engraving procedure, the laser bar invades the material and presents it to heat. Depending on the exposure time, the color changes, or the material is consumed. The subsequent laser engraving is permanent and non-abrasive.
Two methods of engraving
Raster is the simple laser engraving type where, the graph processed from point is recorded point by point.
In vector engraving, once again, the graph consists of lines drawn in constant progress and recorded simultaneously. Vector engraving is often known as “scoring”
What is hand engraving and how it is done
Hand engraving uses a tool known as an engraver. It is pushed on metal cutting a corner crack thus creating a bright line. This is done by three methods: a pusher, a small and light hammer and a chisel and with air driven hammer.
When you look at a thing engraved with a laser and something engraved by hand, there is a great distinction and people are surprised at how much deeper and clearer a thing can be engraved by hand.
The disadvantage of laser engraving is that it does not actually remove the metal, it simply pushes the metal to form the letters or numbers. This causes the engraving to be shallow and because the metal has not been removed, there are around the letters that will feel like a rough edge. The big difference between laser and hand engraving is that by hand, the metal will really be removed, leaving a decent deep cut and a smooth edge everywhere. This deep cut will obviously allow you to read the engraving carefully and, moreover, will not disappear. For example, within a ring or within a bracelet in which it is used daily, polishing it unexpectedly after a time of removing a laser engraving and leaving it black. With your hand, you will find that the cutting and finishing will continue and will obviously be seen many years after.
Because hand-engraving is so flexible, it is not limited to letters. You can record images, for example, stars, hearts, gem shapes and ever more decaying works, such as peaks, ridges and monogram
