Laser Marking on Metal
лазерная маркировка на металле is a contactless approach that requires no extra pre- or post-marking labor.
Laser marking works best on metal, where it is simpler to generate a variety of outcomes. Laser marking and engraving are both clean and accurate. Metal laser markers are the most influential industrial engraving equipment available.
Laser markers do not corrode metal, and the produced mark is acid and corrosive chemical resistant. Furthermore, laser marking devices aid in the reduction of manufacturing time.
Which metals may be laser etched and marked?
There is virtually any metal that cannot be laser marked or etched. The processing processes used for metal identification and engraving are equally extensive: They include annealing and black marking, as well as “basic” and three-dimensional engraving. May use Laser-changing pictures to make beautiful surface structures as well as protective micro engravings.
A vast list of metals that may be laser marked and laser engraved exists, and it includes the following metals, as well as many others that may not mention below:
copper, iron, ferrous metals, magnesium, aluminium, brass, gold, Stainless steel, high-grade steel, carbon steel, silver, platinum, palladium, and titanium
Stainless steel laser marking in the medical industry
Marking medical devices entails far more than simply adhering to requirements. Whether manufacturers are required to comply with worldwide standards and apply all ID markings consistently and with repeat precision, or they are required to assure product quality – all medical items must be correctly tagged in the first place. Absolute traceability is needed to ensure precise part identification. Laser marking is appropriate for creating these marks while increasing production efficiency and reducing costly product trash.
Metal marking with a strong contrast
Complex substrate structures, such as those seen on castings in the automobile industry, may hinder reading the applied codes due to shadows under different lighting situations and weak contrasts.
A well-designed black/white marking improves reading significantly. High contrast may achieve by etching black codes into the metal and then lightening the peripheral and in-between portions.
Aluminium can lids with high-speed laser branding
The Y-series laser marking systems from FOBA is simple to integrate into high-speed manufacturing lines. Allows for the requisite throughput speed to be maintained for oversized batch items such as beverage cans.
Transwell, a Chinese can lid producer, supplies prominent beverage brands worldwide with can lid and employs a FOBA marking method to attach QR-codes and characters.
Steel ball bearings with black markings
Ball-bearing made of typical machining steel (sulfur-free steel) with black annealing marking.
Anodized aluminium dimmer component with laser marking
The marking is created by utilizing a laser to remove the anodized layer off the metal.
Removing anodized layers by laser is a standard application in equipment engineering, where nameplates, front panels, and other components are made.
Stainless steel laser marking in colour
Annealing marking allows for the fabrication of different hues and may even give substrates varied patterns.
Stainless steel and titanium are frequently used in the manufacture of medical devices. Because the local heating process results in colour change rather than material loss, annealing is an excellent marking method when even surfaces are required to prevent germs from entering. Furthermore, these markings are pretty durable.
Before branding, the stainless steel exhibited here was electro-polished. Surface treatments like brushing and micro-abrasive blasting are other options.
Aluminium with a black marking
Local heating of aluminium surfaces, and consequently oxidation, is caused by the laser. This process is known as black marking, and its physical or chemical implications are unclear. The marking results are highly contrasted and resistant to wear.
Inscriptions on cellphones or laptops are frequently inscribed in black on metal.
Laser systems from the FOBA Y-Series are ideal for black marking on metal. The use of the short-pulsed FOBA Y.0201 guarantees that no damage is done to the aluminium surface.
Anodized metal with graded white, grey, and black markings
Different marking effects on the metal result from colour or substance removal. Parts of or the whole anodized top layer are removed using a laser.
Anodizing methods create a ceramic coating (5 to 30 m) on aluminium that protects and scratches the surface. Because the porous layer may be coloured, it can achieve beautiful marking effects. The effects of marking vary depending on the laser wavelength (and consequently the thickness of removed material) and the colour of the underlying layers.
Anodized aluminium is commonly used in machine construction, such as housing components, covers, adjusting screws, etc.
Anodized aluminium may be marked using FOBA lasers from the Y-Series (such as the Y.0100, Y.0200, and Y.0300).
