Laser marking know-how might be the greatest computer software parts of laser processing. Laser marking is commonly a marking technique that employs a big Energy density laser to regionally irradiate the workpiece, causing the ground compound to vaporize or undergo a chemical reaction of shade modify, As a result leaving a long-lasting mark. Laser marking can make An array of persons, symbols and patterns, and lots of Other individuals. The character measurement can range between millimeter to micron scale, that is of Unique worth for item anti-counterfeiting.

Laser coding standard theory

The fundamental essential theory of laser marking is the fact a big Energy continuous laser beam is generated by the laser generator, in addition to the centered laser capabilities within the substrate supplies, bringing about the floor product to melt right away or simply vaporize, and by managing The trail while in the laser on The material flooring, the specified graphic mark is fashioned.

Characteristic I

Non-Speak to processing, is often marked on any formed region, the workpiece won't be deformed and crank out interior strain, like minded for metal, plastic, glass, ceramics, Picket, leather-based together with other means marking.

Attribute two

Basically all elements (which include piston, piston ring, valve, valve seat, factors devices, sanitary ware, electronic factors, and several Other people.) is often marked, combined with the mark is placed on-resistant, the producing course of action is really a snap to attain automation, and in addition the marked factors have little or no deformation.

Attribute A few

Using the scanning strategy for marking, that is definitely, the laser beam is incident on The 2 mirrors, utilizing Personal computer-controlled scanning motor drives the mirror together the X and Y axis rotation, respectively, the laser beam is concentrated and falls more than the marked workpiece, For that reason forming a laser mark trace.

Laser coding positive aspects

1. The laser target the unbelievably high-quality laser beam as a knife, the issue floor space articles is frequently taken off problem by place, its Point out-of-the-artwork is undoubtedly the marking procedure for non-Get hold of processing, is not going to generate mechanical extrusion or mechanical worry, so will never hurt the processed merchandise; because the laser cope with the size of an exceedingly compact, very small heat-affected position, processing great, Therefore, can total some typical techniques are not able to acquire the treatment.

2. The "Instrument" Employed in laser processing is definitely the concentrated level of sunshine, so There is no must increase other machines and supplies. Laser processing is quickly and low-priced. Laser processing is right away controlled by a computer and consists of no human intervention for that period of technology.

a few. The laser can mark what sort of information, only with the computer type information and facts, furnishing the computer design and style and layout of the marking approach is frequently regarded, then the marking gear could be intended to accurately restore the information on the appropriate company. Consequently, the objective of the application essentially decides the intent within the procedure to a sizable extent.

Whilst during the SMT field of laser applications, predominantly In the PCB for laser coding traceability, and numerous wavelengths of laser hurt to the PCB mask tin layer is inconsistent.

The lasers now utilized for laser coding are fiber laser, UV laser, green laser and CO2 laser. The lasers routinely Employed in the sector are UV laser and CO2 laser, and fiber laser and environmentally friendly laser are alternatively less made use of.

Fiber laser

Fiber pulsed laser is often a laser created by making use of unusual earth factor (such as ytterbium) doped glass fiber as staying a get medium, with an exceptionally ample luminous Electrical energy stage, pulsed fiber laser wavelength of 1064nm (much like YAG, the key variation is that the Performing material of YAG is neodymium) (QCW, continuous fiber laser widespread wavelength of 1060-1080nm, Whilst QCW is additionally a pulsed laser Although QCW is Also a pulsed laser, but its pulse technology program is totally diverse, the wavelength can be unique), is frequently a during the vicinity of-infrared laser. It can be employed to mark the two of Those people metallic and non-metallic elements on account of its important absorption cost.

The method is acquired by employing the thermal result with the laser on the material, possibly by heating the place layer of the fabric to reveal a even more layer of Yet another colour, or by microscopic Real Actual physical variants that come about around the ground of The material when heated by gentle Vitality (e.g., some nano- or 10-nanometer micropores supply a black human entire body affect, and lightweight isn't mirrored, creating The material appear to be deep black) and generating A serious modify in its reflective Houses, or Some chemical reactions manifest when ezcad laser marking software download The sunshine Energy is heated, together with the essential details and details for example graphics, people, and 2nd codes are demonstrated.

Ultraviolet Laser

UV laser is a short wavelength laser, generally employing frequency doubling technological innovation to transform the infrared mild (1064nm) emitted from the trustworthy-condition laser into UV Mild at 355nm (triple frequency) and 266nm (quadruple frequency). Its photon Electrical electricity is so massive that it'd match the energy levels of specified chemical bonds (ionic bonds, covalent bonds, steel bonds) of nearly all substances in character, appropriate interrupting the chemical bonds and developing photochemical reactions in elements devoid of clear thermal results (selected Electrical power amounts of atomic nuclei and interior electrons can take up UV photons then transfer the Electrical electricity Through lattice vibrations, producing thermal effects, although not apparent), and belongs to "chilly processing". For The rationale that there is not any visible thermal impact, UV lasers can not be used for welding and so are commonly helpful for marking and precision reducing.

The UV marking procedure is completed through the usage of a photochemical reaction amongst UV Mild and the material creating a modify in colour. Working with suitable parameters, a visual elimination impact on the fabric area could be averted, Therefore letting the marking of graphics and figures that are not visibly tactile.

Despite the fact that UV laser can mark the two metal and non-metal, due to Expenditure component, Generally use fiber laser to mark metallic merchandise, and use UV laser to mark things with important ground higher-quality prerequisites and challenging to recognize with CO2, and type a larger and modest match with CO2.

Eco-pleasant Laser

Eco-friendly laser can be a brief wavelength laser, commonly making use of frequency doubling know-how to transform the infrared mild (1064nm) in the secure indicate laser, into eco-welcoming Light at 532nm (two circumstances the frequency), eco-friendly laser is witnessed gentle-fat, UV laser is invisible Light. Green laser photon Power is rather substantial, and its chilly processing characteristics are really similar to UV gentle-fat, that may form a several selection with UV laser.

Inexperienced gentle marking system and UV laser is similar utilization of environmentally friendly delicate and the material photochemical response resulting in colour adjust to attain, the usage of excellent parameters can avoid the obvious elimination impact on the ground of The material, and so can be marked with no acquiring apparent tactile graphics and folks, PCB board region commonly includes a layer of mask tin layer, there tend to be various forms of colours, inexperienced gentle laser and its reaction impact is superb, marking out the graphics incredibly unique and delicate.

CO2 laser

CO2 is usually a Generally utilized fuel laser, by making use of a wealthy luminous Ability stage, prevalent laser wavelength of nine.three, ten.6um, can be quite a noticeably-infrared laser, continual output Electrical power of just about tens of kilowatts, generally employing a modest-Strength CO2 laser to complete the marking means of polymer along with other non-metallic products and solutions. CO2 lasers are typically rarely utilized to mark metals as being the absorption amount of money of metals is extremely minimal (you can Lessen and weld metals with excellent electrical electrical power CO2, which includes been slowly improved by fiber lasers resulting from absorption stage, electro-optical conversion level, optical route and routine maintenance).

CO2 marking procedure is arrived at by making use of the thermal influence within the laser on the fabric, each by heating the place layer of the fabric and revealing the deeper layer of varied hues, or due to microscopic Genuine physical modifications that arrive about on the area area of The material heated by moderate Strength, triggering big modifications in its reflective Houses, or by particular chemical reactions that manifest when heated by light Electrical energy, leading to the specified graphics, people, two-dimensional codes together with other information and facts.

CO2 laser is mostly Used in Digital factors, devices, garments, leather-based-based mostly, baggage, footwear, buttons, Eyeglasses, drugs, food stuff stuff, beverage, cosmetics, packaging, electrical equipment together with other fields utilizing polymer sources.
