LASER is the method of emitting electromagnetic radiation, such as visible light or light through the process of stimulating emission. Laser is an abbreviation for Light Amplification through Stimulated Emission Radiation.
The expanding quantity of industries as well as the increasing competition between them will make them adopt new technology. This has led to the the introduction of laser systems to perform a wide range of industrial tasks, such as cutting marks, marking embossing, engraving and embossing. The main difference between laser marking systems compared to other types of marking is the distinctive mixture of performance, durability and the versatility of computer control. The software that is used in the laser marking is accessible through PCI interface cards. The card transmits digital signals from the computer-based marking file to the motors and sends the laser beam towards the item being marked with lasersdesktop laser marking machine.
Lasers for marking are:
CO2 Lasers creates permanent codes for life-long traceability. This will lower manufacturing costs and is easily integrated with automated systems.
Excimer Lasers can be found in these UV light wavelengths of 157 nm 193 nm nm 308 nm, 351 nm. It is mostly used on Inkjet Drilling Nozzles, Marking Eyeglasses etc.
The YAG Lasers are commonly used as a base platform to produce various wavelengths when properly set up. The most flexible wavelength available is Infrared (1064nm). It is utilized to identify the various types of materials like ceramics, metals and composites and plastics.
The various types of processes that are involved within laser marking system include:
Surface Annealing
Surface annealing pulls carbon and/or oxides out of the base material, making a distinct mark. The beam that marks will create a sharp line of contrast to the surrounding areas with little or any penetration. This is ideal for situations that require a smooth, un-damaged surface and contrast are required. Surface annealing is utilized predominantly on medical implanting tools, bearings and bearings.
Surface Etching
Surface etching allows you to alter reflectivity and enhance contrast of the metals by altering the finish of the metal’s surface. It is among the most frequently used laser marking techniques whose penetration depth is usually less than 0.0001″ deep.
Ablating
Ablating can be used to add contrast, without harming the base material. This technique is usually done using the backlit button, anodized aluminum and steel that has been painted.
Thermal Marking
This method is based on managing heat with different laser parameters, including the speed of marking, energy, frequency and the focus. It is mostly used on certain alloys that causes color changes.
Engrave Marking
The required depth is created by the vaporization process of the base material. This type of marking is the same as the surface etching method; it is usually used in 0.0001″ to 0.005″ depth. Repeated passes can make the mark deeper. mark.
Specialty Marking
The system for marking specialties is used extensively in plastics. There is a changes in contrast that occur naturally in certain plastics through heating or pairing with wavelengths that results in a chemical change. Additives can be utilized in conjunction with many plastics to create various shades. One instances of specialty marking includes Product Traceability, which is the ability of a company to trace a product’s path through its processes and also to be able to trace products back to the manufacturer.
