Laser marking is an ink free, contact less, direct on part, permanent marking solution, fulfilling regulations, adding discrepancy to ones parts by using a fine spot laser beam focussed on the surface of the product. The laser beam slightly alters the surface without burning it typically inducing a color change within the material, and hence no surface modification.
Sub surface Laser engraving is a non-conventional, non-contact type of machining process of engraving an image by removing a portion of material, layer by layer to leave a precise deep mark on the surface which is in a range of few microns.
Laser beam welding is a technique in manufacturing which uses high intensity laser beam for joining different materials together. The characteristics of laser beam is that it is coherent and have monochromatic wavelength. The laser beam has high energy content and very low divergence. It produces heat when it strikes the surface.
Annealing marking is an oxidation process used on carbon containing metals by applying heat through laser on the surface of any metal. Annealing marking generally gives a black mark with a smooth finish, but color may vary from brown, red, green etc. depending upon the heat used for marking.
Laser ablation is a reliable, efficient and cost effective process of removal of layers from solid metals or industrial
compounds using laser beams for high precision to expose the covered layer. Common coating removals include perylene,
poly-amides, silver chloride and gold, but many others are possible. The amount of layers that is removed depends on the
intensity, pulse length, and wavelength of the laser, and the material itself.
Foaming is a laser marking technique used only on polymers. Laser foaming is carried out by creating a molten burn on
the surface. The molten surface creates an atmosphere of foaming gas bubbles. Foam laser marking is usually carried on a
polymer which results in a light color.
Laser cutting has established itself as one of the most viable contenders for many applications and has become the most widely used application in micro machining. It competes with the traditional methods of cutting like punch pressing and more recent plasma arc cutting and EDM, but stands out for its ease of fixturing, cutting complex shapes, high rate and low cost for voluminous applications, small kerf, speedy set up and ease of automation.
Micro-drilling by laser relies on controlled removal of material exposed to high-intensity laser irradiation. Usually, this term is applied to holes or openings with diameters between 1 µm to 1 mm. The exact mechanisms of material removal during micro-drilling are defined by the material properties, characteristics of the laser, and the configuration of the machining process.
