Laser marking / Laser engraving

Laser marking is possible with our Kolltronic ® laser systems on all metals and plastics (fiber lasers), as well as organic materials (CO2 lasers) that can be lasered.

The upper surface layer of the material is removed and a depression, the engraving, is created. This engraving is smudge and waterproof.

Annealing marking

A colour change can be achieved on metals by heating the material. The oxidation process takes place on the surface, so that the material surface remains flat and is not removed. Depending on temperature and material, this oxide layer can turn out not only black but also coloured.

Logos / Data-Matrix-/ QR-/ Barcodes

In addition to logos, fonts and numbers, the application of different codes such as data matrix codes, QR codes and barcodes 128 EAN is possible.
Whole files can be imported as dxf, eps, jpg, bmp, dwg, eps and other formats.

Foaming/ colour change

Carbon oxidizes when plastics are heated, forming a foam layer. Depending on the colour of the plastic, this layer is light or dark. This application is only possible with plastics.

Material removal/ paint removal

On lacquered or coated materials, laser inscription can be achieved by targeted colour or material removal, in which the colour of the underlying material becomes visible. This is used in the automotive industry, for example, to produce operating elements that are illuminated from behind.

Varnish removal from metal parts

High-speed cleaning for the removal of rust or paint from various materials.

Deep engraving

Creating a deep engraving with the very fine laser beam is only a matter of time. Over a multitude of repetitions, the laser beam works its way deeper and deeper into the material from layer to layer. Depths of 0.1-0.2 mm can be created in tool and mould making. This technology is also used in the production of coin minting dies.

Plastic labeling

Für die Beschriftung von Kunststoff bietet SK LASER unterschiedliche Laser. Je nach Anwendung kommen dabei Faserlaser, Grünlichtlaser oder UV-Laser zum Einsatz.

Wire stripping

Strip cable with SK LASER.
Depending on the material, powerful CO2 type lasers with 10,600 nm or fiber lasers with 1,064 nm with up to 450 watts of power are used.

Textile surfaces Partial fine removal

High-speed cleaning for the removal of rust or paint from various materials.

Laser cutting of metal foils up to 1mm

Metal foils of different materials cut up to a thickness of 1mm.

Wood cutting

Cut wood up to a thickness of 2 mm.
At the same time a marking can also be applied to the wooden part.

Varnish removal from metal parts

High-speed cleaning for the removal of rust or paint from various materials.

Material removal

High-speed cleaning for the removal of rust or paint from various materials.

Plastic Welding

The laser beam passes through the white plastic from the outside without damaging it and is absorbed by the black plastic. The resulting melt causes both plastics to be welded together.

Textile surfaces Partial fine removal

 Laser cutting is an alternative to the mechanical removal of sprue from injection molded parts. For this purpose, 200 Watt and 400 Watt CO2 lasers are used. The advantage of the process is its flexibility and low operating costs. There is virtually no wear.

Nowadays, mass products made of plastic are often produced by injection moulding. Moulded parts such as acrylic panels are also pressed into moulds by injection moulding. For production reasons, sprues remain in the mould, which must be separated in a separate operation. The simple demolition is usually too messy. If the residues are removed by machining, particles are always produced which adhere to the workpiece due to the static charge and make further processing difficult or even prevent it. This makes reworking necessary, which in turn is associated with costs. Laser cutting offers an ideal solution for this, whereby the entire process can be fully automated.

SK LASER offers suitable solutions for this purpose, consisting of laser and robot, which have been developed with leading manufacturers in the industry. The laser has been integrated into the production, the entire system works fully automatically. The workpieces are provided from the upstream step in a tray and taken over by a robot. This robot guides the injection moulded part into the laser and positions it exactly. The robot moves the injection-moulded part in interaction with the laser and its controller. In doing so, the sprue is cut off true to shape and a clear edge is created which does not need to be reworked.

Foil cutting / Kisscut

Film cutting with semi-automatic or fully automatic machines from SK LASER. Kisscut as shown on the photo is possible. SK LASER offers CO2 lasers up to 600 watt power.

Laser cutting of fleece

Laser cutting of foils and fleece with lasers from SK LASER offers many advantages, such as clear edges, exact dimensions, fusing of edges and quick adaptation to new shapes .
