Laser Engraving

Laser engraving is a technique in which laser technology is used to engrave, mark or etch any object. People get things engraved for many different reasons and purposes. This method is much more popular than other engraving procedures because the result is very clean and precise. The method of laser engraving can be very complex and technical, and involves exposing the object to a laser ray.

The machine which is used for laser engraving basically has 3 main parts, which are the laser, controller and surface. The laser beam is emitted from the laser, and the patterns are traced by the controller onto the surface.

A laser is so powerful that it can not only engrave, but also cut if necessary. Plasma cutting and woodcarving are techniques that can take place with the help of a high-power laser. Printing on disposable cups, plastic bags, candy bar wrappers and milk cartons is done by a method known as ‘flexo printing’, which is done with the help of laser engraving.

Mostly, laser engraving is used for materials which are “laser-able”, like alloys and polymers. Woodwork, a very beautiful and famous art, is carried out with the help of laser engraving. Here, 10 watts of laser power can suffice to engrave on hardwoods like oak and mahogany. Acrylic plastics and plastic sheets (of soft drink bottles) are also commonly engraved. By the method of conduction, coating can be removed from metal with the help of laser engraving. Diamonds get their brilliance thanks to the process of laser engraving.
