Posted by Neal on December 20th, 2020

Laser marking technologies is probably the major software parts of laser processing. Laser marking is definitely a marking system that utilizes a massive Power density laser to domestically irradiate the workpiece, producing the surface area resources to vaporize or undergo a chemical reaction of coloration renovate, That's why leaving a long-term mark. Laser marking can create quite a few people, symbols and patterns, etcetera. The character sizing can differ from millimeter to micron scale, which may be of Distinctive importance for product anti-counterfeiting.

Laser coding principle

The crucial theory of laser marking is The truth that a substantial Electrical energy continual laser beam is made because of the laser generator, along with the centered laser acts in excess of the substrate merchandise, building the floor components to soften at once and also vaporize, and by managing The trail with the laser on the fabric area location, the specified graphic mark is fashioned.

Element I

Non-Get maintain of processing, is frequently marked on any fashioned area spot, the workpiece will not be deformed and create inside worry, suitable for metallic, plastic, glass, ceramics, Picket, leather-based and several provides marking.

Attribute two

Just about all parts (for instance piston, piston ring, valve, valve seat, hardware machines, sanitary ware, Digital aspects, etcetera.) may be marked, moreover the mark is costume in-resistant, the output system is straightforward to comprehend automation, moreover the marked pieces have modest deformation.

Function three

Using the scanning technique of marking, that is definitely unquestionably, the laser beam is incident on The 2 mirrors, the use of Notebook or Laptop or computer-controlled scanning motor drives the mirror together with the X and Y axis rotation, respectively, the laser beam is concentrated and falls over the marked workpiece, Consequently forming a laser mark trace.

Laser coding Added benefits

one particular. The laser center on the extremely significant-high-quality laser beam getting a knife, the thing surface product might be eradicated phase by laser marking machine manufacturers posture, its Advanced often is the marking strategy for non-Get in touch with processing, will likely not crank out mechanical extrusion or mechanical pressure, so will unlikely harm the processed merchandise; since the laser target the scale of a really small, compact warmth-afflicted put, processing excellent, as a result, can end some conventional procedures are unable to understand the strategy.

two. The "Product" Employed in laser processing might be the specific stage of sunshine, so there isn't a need to include other equipment and things. Laser processing is promptly and cheap. Laser processing is right away managed by a computer and necessitates no human intervention by era.

three. The laser can mark what type of knowledge, only with the pc style and design posts, so long as the pc structure while in the marking course of action could be acknowledged, then the marking device could be built to correctly restore the information on the appropriate carrier. That's why, the operate about the computer program in actual fact establishes the function within the application to a big extent.

In the SMT field of laser apps, generally in the PCB for laser coding traceability, and distinct wavelengths of laser damage to the PCB mask tin layer is inconsistent.

The lasers presently used for laser coding are fiber laser, UV laser, inexperienced laser and CO2 laser. The lasers typically Used in the market are UV laser and CO2 laser, and fiber laser and eco-friendly laser are reasonably significantly significantly less used.

Fiber laser

Fiber pulsed laser might be a laser created by making use of unusual earth ingredient (like ytterbium) doped glass fiber for being a get medium, with an extremely loaded luminous Electric power stage, pulsed fiber laser wavelength of 1064nm (comparable to YAG, the real difference can be which the Doing the job content of YAG is neodymium) (QCW, continual fiber laser typical wavelength of 1060-1080nm, Even though QCW is often a pulsed laser Although QCW is additionally a pulsed laser, but its pulse technology procedure is completely unique, the wavelength is often exceptional), is frequently a close to-infrared laser. It can be utilized to mark both equally of those metallic and non-metallic materials on account of its substantial absorption payment.

The method is attained by using the thermal final result to the laser on the fabric, either by heating the ground layer of the fabric to reveal a even more layer of A further colour, or by microscopic physical adjustments that come about throughout the ground of The material when heated by gentle Strength (e.g., some nano- or 10-nanometer micropores generate a black All round overall body influence, and lightweight is rarely mirrored, creating the fabric display up deep black) and generating an enormous change in its reflective Homes, or Some chemical reactions arise when The sunshine Electrical power is heated, and demanded specifics like graphics, figures, and 2nd codes are displayed.

Ultraviolet Laser

UV laser is a short wavelength laser, normally utilizing frequency doubling technologies to rework the infrared gentle (1064nm) emitted with the responsible-situation laser into UV Mild at 355nm (triple frequency) and 266nm (quadruple frequency). Its photon Vitality is so massive that it could potentially match the Electrical power amounts of specific chemical bonds (ionic bonds, covalent bonds, metal bonds) of just about all substances in character, ideal interrupting the chemical bonds and creating photochemical reactions in materials without having obvious thermal results (certain Electrical power quantities of atomic nuclei and interior electrons can take in UV photons and Later on transfer the Strength via lattice vibrations, establishing thermal outcomes, Though not evident), and belongs to "chilly processing". Mostly because there isn't a obvious thermal effect, UV lasers can not be used for welding and they're usually useful for marking and precision slicing.

The UV marking system is obtained by utilizing a photochemical response in between UV gentle-fat and the fabric resulting in a make improvements to in coloration. Making use of satisfactory parameters, a visible elimination impact on The material flooring could possibly be avoided, Due to this fact making it possible for the marking of graphics and characters that aren't visibly tactile.

Though UV laser can mark both equally metallic and non-metallic, resulting from Benefit variable, often use fiber laser to mark steel sources, and use UV laser to mark remedies with superior flooring high-quality prerequisites and complicated to carry out with CO2, and sort a large and very low match with CO2.

Eco-pleasant Laser

Inexperienced laser is normally a brief wavelength laser, ordinarily working with frequency doubling technological innovation to transform the infrared light-weight (1064nm) with the solid ailment laser, into green Mild at 532nm (two occasions the frequency), eco-friendly laser is apparent Light, UV laser is invisible moderate. Eco-friendly laser photon Strength is sort of enormous, and its chilly processing traits are extremely much like UV mild, which frequently can form a various wide variety with UV laser.

Environmentally friendly mild-body weight marking system of motion and UV laser is identical use of inexperienced moderate and the fabric photochemical response resulting in colour adjust to obtain, using correct parameters can stop the apparent getting rid of impact on the surface area of the fabric, and so could be marked without clear tactile graphics and men and women, PCB board surface commonly features a layer of mask tin layer, there are generally many types of colours, inexperienced moderate laser and its response effect is superb, marking out the graphics incredibly evident and sensitive.

CO2 laser

CO2 is generally a usually utilized gasoline laser, which has a prosperous luminous Electricity degree, standard laser wavelength of nine.three, ten.6um, is usually a A great deal-infrared laser, frequent output electricity of as many as tens of kilowatts, commonly employing a compact-electric power CO2 laser to finish the marking approach of polymer and different non-metallic products. CO2 lasers are usually rarely accustomed to mark metals as being the absorption total of metals may be extremely small (it is achievable to Slice and weld metals with high electric powered power CO2, which has been step-by-step replaced by fiber lasers ensuing from absorption fee, electro-optical conversion cost, optical route and servicing).

CO2 marking approach is achieved by employing the thermal influence within the laser on The material, both of those by heating the ground layer of the fabric and revealing the further layer of assorted colours, or as a result of microscopic Actual physical modifications that come about concerning the area of the material heated by gentle-excess weight Vitality, creating substantial alterations in its reflective Attributes, or by absolutely sure chemical reactions that happen when heated by light Energy, resulting in the specified graphics, characters, two-dimensional codes in addition to other info and specifics.

CO2 laser is Ordinarily Utilized in Digital components, instruments, outfits, leather, luggage, shoes, buttons, glasses, medicine, foodstuff, beverage, cosmetics, packaging, electrical resources together with other fields making use of polymer sources.
