Sandblasting or sandblasting is an effective and fast surface cleaning process that is widely used in various industries. This technology is a method used instead of physical cleaning and manual sanding, which provides much faster and more efficient results. During sandblasting, abrasive particles (usually sand) are blown onto the surface to be cleaned using high-pressure air. This method is excellent for quick and thorough cleaning of rusty, painted or otherwise contaminated surfaces.

Laser cleaning is an innovative technology that is widely used in industries to clean and prepare surfaces. This method offers many advantages over conventional mechanical, chemical or other physical cleaning processes. Laser cleaning is an effective method for removing rust and oxide layers on metal surfaces. Also, laser cleaning quickly and efficiently removes paints and various coatings from metals, plastics or composite materials. This is particularly useful in the automotive and aerospace industries, where surface preparation is important before painting or coating.

Color marking on metal utilizes various laser technologies to create durable and aesthetic color patterns and inscriptions on metal surfaces. This technology is excellent for industrial signage, art projects, and personalized product creation. Below, I will explain in more detail how this technology works, the types of metals it can be used on, and the advantages it offers.

How Does Color Laser Marking on Metals Work?

Use of a Laser Beam

The laser marking equipment emits a concentrated laser beam that can machine microscopic points on the metal surface. The heat and energy of the laser induce various chemical and physical reactions on the surface.

Creating Colors Using Different Methods

Oxidation: When certain metals, such as stainless steel, are treated with a laser, an oxide layer forms, which can result in different color shades. Different colors can be achieved by varying the thickness of the oxide layer and adjusting the laser parameters (e.g., intensity, speed, frequency).

Heat Treatment: The temperature changes produced by the laser can create various color shades on the metal surface. These color changes are caused by alterations in the crystal structure and surface of the metal due to heat.

Material Coatings: Special coatings are applied to some metals, which, after being treated with a laser, display different colors. These coatings can be oxide layers, paints, or other special materials.

Software Control: Laser marking is controlled by software, enabling precise and detailed realization of any pattern, text, or graphic. The software allows users to adjust the laser parameters to achieve the desired colors and patterns.

Applicable Metals

Stainless Steel: One of the most commonly used metals for color laser marking, capable of producing different colors through oxidation.

Titanium: Responds well to laser heat treatment, offering various shades.

Aluminum: Can be color-marked using special coatings and oxidation processes.

Copper and Brass: These metals can also be suitable for color marking, particularly when special coatings are applied

Laser technology has many advantages and can be used in several industries.

Laser milling has many advantages

Thanks to the programming, it handles vector graphics well, so it is ideal for milling complex shapes and forms, and is able to achieve micron-scale detail. In addition, the equipment can be widely used, starting from plastic to metals, and can grind even on more sensitive materials at a high level, as it can be tuned very finely, so even the sponge will not burn. Its speed is also worth mentioning, as it works on both thinner and thicker materials at an excellent speed, which reduces milling time and increases productivity. What is perhaps the most different from traditional technologies is that there is no tool wear, as the entire process is contactless.

Precision laser welding is a process that is extremely precise and controlled, allowing the welding of very thin or complex parts.

Advantages of laser welding

Precision laser welding has many advantages, including accuracy, high speed and efficiency, non-contact and temperature optimization.

Laser welding is a very precise and controlled process, thanks to which it is possible to weld parts with small details and complex geometries.

The laser beam is an efficient process because it melts the materials in seconds, resulting in fast welding and high productivity.

Contactless process, so there is no direct physical contact during the process, as the procedure is fully automated.

It reduces deformation and damage to heat-sensitive materials, as there is minimal temperature influence during welding, i.e. the heat release is concentrated. Thanks to this, we can make thin and precise seams.

Precision laser cutting is an essential technology in modern manufacturing, offering unparalleled accuracy and versatility.

Benefits

Versatility: Can cut a wide range of materials and thicknesses.

Quality: Produces clean cuts with smooth edges, reducing the need for additional finishing processes.

Automation: Can be integrated with CAD/CAM systems for automated and repeatable cutting processes.

Reduced Waste: Minimizes material wastage due to the precision and efficiency of the process.

Laser milling is a modern processing technology that uses laser beams to remove material from the base material. During the process, we can create different patterns, shapes, inscriptions, we can even create differences in levels, because the laser cutter can trace the topology. Thanks to our unique development, we can also do 2D and 3D laser milling, and thanks to our program, we can also mill complex patterns and shapes. The technology also has many advantages over traditional milling technologies, especially precision, micron-accurate milling, speed and versatility.

Advantages:

High accuracy and precision: Thanks to the programming, it handles vector graphics well, making it ideal for milling complex shapes and forms, and capable of micron-sized detail.

Speed: It works with excellent speed on both thinner and thicker materials, reduces milling time, thereby increasing productivity.

Material selection: It can be used in a wide range of applications, from plastic to metals, the equipment can also grind on more sensitive materials, as it can be tuned very finely, so the sponge won’t burn either.

No Tool wear: The process is non-contact, so there is no tool wear, which reduces maintenance costs and downtime.

Clean and Smooth Milling: There are no burrs during milling, so there will be no waste. During the process, only dust is generated, which is removed from the milling area by suction, so it is an environmentally friendly solution. The result is an excellent surface quality, which requires minimal post-work or can even be dispensed with.

Color laser marking is not a widespread technology, but rather interesting from a design point of view. It is suitable for creating patterns and inscriptions in different colors. The colors can be created using several methods, all that is needed is the right raw material and setting. During the laser treatment of certain metals (e.g. stainless steel), an oxide layer is formed, which results in different shades of color.

Colored marking offers many advantages, it is just as durable as simple marking, resistant to wear, chemicals and drastic changes in temperature. High-resolution, detailed markings can be easily created based on vector files, and a print image can almost be converted. The process is fast and fully automated, as with other laser technologies.
