Engraving involves cutting or carving letters, characters, or images on materials. Industrial methods include stenciling, CNC, and laser engraving. Stenciling and etching use chemical compounds, while CNC uses a computer to control the process. Laser engraving fuses marking materials to a hard surface using a laser, making the engraving permanent and adding color.
Engraving is a type of marking method that involves printing or designing letters, characters or images by cutting or carving with some kind of apparatus. Industrially, this may involve engraving mass-produced items such as dog tags, plaques, trophies or metal plates. Custom engraving is popular with consumers because it allows for the personalization of certain items and products. There are many different methods of industrial engraving which all have their advantages and are used for particular products. These methods include the use of stencils, CNC and laser engraving machines.
Stenciling and etching is a common type of industrial printmaking that uses chemical compounds to create letters or images. Etching and stenciling involve a process of immersing a covered piece of material in a chemical bath. The material can be plastic, metal or any other type, but the chemical used varies according to the material. It only has certain parts covered so the chemicals only affect the exposed parts. These exposed parts are slowly eaten away by the chemical, creating a pattern in the material that can be seen once the stencil is removed.
Computer numerically controlled, or CNC, engraving has become an increasingly popular type of industrial engraving that uses CNC machines to control an engraving process by the use of a computer. This machine has a spindle and drive system that are manipulated by a computer to engrave or cut material in a certain pattern along three axes of a plane. It engraves based on data entered by a user and produces the engraving very quickly. This process is advantageous on an industrial level because it allows items such as dog tags or plaques to be mass-produced at high speed. It is also useful for industrial purposes because it reduces manual work.
Another type of industrial engraving used on a large scale is laser engraving. This type of engraving uses a combination of precise lasers and marking materials to produce engravings on metal, ceramics and glass. The process is a chemical process that uses marking material and fuses the materials to a hard surface using a laser. This process makes the engraving permanent and each marking material is chemically mixed according to the material it will bond to. Laser industrial engraving is unique in that it can engrave and add color to the engraving at the same time, making the engraving more individual.
