Basic concept of marking machines

Marking machines are devices designed to print, etch or stamp permanent information on surfaces made of various materials. This information may include serial numbers, codes, logos, manufacturing dates, and other traceability and quality control data. They are widely used in industry to ensure the identification of parts, components and finished products.

Marking can be done using different techniques, such as laser, micropercussion, scratching or stamping, depending on the type of material and the specific application. Technological evolution has allowed automation and improvement in the precision and speed of marking processes, being essential in sectors such as automotive, aerospace, electronics and pharmaceuticals.

Micropercussion marking machines

Dot peen marking machines work by repeatedly striking the surface of the material with a punch to create a series of dots that form characters or symbols. This method is especially useful for hard metals and irregular surfaces, providing a durable, abrasion-resistant marking.

They are mainly used in industrial applications where high marking durability is required, such as automotive parts, tools and electronic components. Micropercussion allows controlled marking depth and can be automated for production line processes.

These types of machines are usually robust, with numerical control systems that allow different patterns and texts to be programmed. In addition, its maintenance is relatively simple, although it requires periodic adjustments to maintain the precision of the punch.

laser marking machines

Laser marking machines use a focused laser beam to modify the surface of the material, achieving a precise, clean marking without physical contact with the piece. They are mainly used for fine engravings and complex details on metals, plastics, glass and other materials.
