Laser Macro - The Power of Light

In both the cutting and welding of body parts, and the manufacture of vehicle components, the future belongs to innovative laser systems.

Various thicknesses and qualities of metal sheet can be welded together to form tailored blanks, and laser seams can replace electric spot welds.

Laser Flame Cutting

In principle, the cutting of metals with the laser is effected by locally heating the material to above melting point at the focal point of the focused laser beam

. The resulting smelt is ejected by a gas that is injected coaxially to the laser beam, so that an open cut is formed

Laser Fusion Cutting

Cutting in two dimensions, which is the most common case, is the domain of the CO2 laser, because it yields the best cost-benefit ratio

Dieboards

For this application CO2 lasers are used, because the beams of other types of laser are not absorbed by wood.

It is the flexibility of laser cutting, coupled with the high degree of precision and quality of cut, that makes it interesting for this application

Glass

When cutting quartz glass, the advantages of the laser over traditional cutting processes lie in the absence of wear on the beam, which works contact-free.

Furthermore, the laser technique creates a significantly improved quality of cut compared with other processes.

IHT Cutting

Internal high-pressure transformed (IHT) components are being used increasingly in automobile construction to achieve stiffness in bodies and components

Plastics

Thermoplastics can be cut by comparatively low-power CO2 lasers in the range of 100 to 300 Watts.

Depending on the setup of the application, separation cuts or polishing cuts (visually clean cut edge) can be carried out.

Textiles Because of the great variety of products in automobile construction, and the associated manufacturing processes, basic components of the vehicles' interior trim vehicle are to an increasing extent being cut to shape individually.

In these cases, CO2 lasers with typical power ratings of 300 Watt are used, because they can cut even compound materials like textile / plastic at speeds of up to 5 meters per minute

CO2 LASER –HEAT TREATMENTHardening The high-power diode

laser, with its rectangular beam, a "top-hat" intensity distribution in one beam direction ("slow-axis") and a Gaussian curvature in the other ("fast-axis"), is particularly suitable for wide-area surface-treating applications.

One advantage over the CO2 Laser is the short wavelength (808 nm and/or 940 nm), which leads to higher absorption and thus dispenses with the blackening that is necessary when CO2 lasers are used

Laser Micro - focus on Fine Solutions

The increasing miniaturization in electronics, semiconductor manufacturing and medical technology is opening up unique opportunities for the use of lasers.

Fine cutting

High-grade steel

Laser cuts are not only fine and made at high speed; they are remarkably burr-free and are characterized by a minimal warming zone.

High-quality cuts are achieved by a high degree of overlap in the laser pulses - in many applications, pulse frequencies between 1000 and 4000 Hz are therefore necessary.

Paper

Examples in which paper, foil or labels are already being cut in series by lasers today, are adhesive labels, variably designed present cards or prototypes in moderate quantities.

PMMA

As a rule, CO2 lasers with Galvanometer-driven deflector heads are used for fine cutting of PMMA.

This ensures maximum precision and speed.

Titanium

Mechanical processing is usually possible only at very low feed rates, and causes heavy wear on tools.

Here, laser-beam cutting provides an excellent alternative, allowing cross-sections of up to approx. 2mm to be cut.

Heating elements

The stainless steel heating element measures approx. 30 cm x 20 cm, and was cut with a feed rate of 20 mm per second

Filter

several thousand fine slits have been cut in stainless steel sheeting for a fluid filter.

Up to 500 slits per square centimetre can be cut this way.

Medical devices gen.

Scalpels

Stents

Micro drilling

The flexibility and speed of laser technology can be used to advantage in the drilling of blind and through-going holes with a diameter of less than 100 µm.

Ablation of thin films

Precise, local ablation of thin layers of material is finding its way into many different areas of industrial production.

The basis of all these applications is an ablation process that is characterized by short, high-energy laser pulses that cause ablation of the material

Scribing

By following the same contour once or several times, of course, even thicker areas of the surface can be structured 2-dimensionally

Engraving

Laser supported, high-volume ablation offers excellent opportunities for making high-precision printing, embossing, erosion, or injection tools

Perforating

Roll materials such as cigarette-tip paper or packaging foil for the food industry are perforated using special, high-frequency excited, fast modulating CO2 lasers with extraordinary power stability

Laser Marking - The Mark of Excellence

Anodized Aluminum

Laser marking of anodized aluminum means that the top layer of aluminum oxide gets removed to expose the basic material.

Frequently the top layer is very thin ( a few thousandths of millimeter, therefore high marking speed can be realized.

Electrical components

Plastic parts and housings are generally easy to mark with laser marking methods.

Our laser systems are capable of integrating variable contents, such as coding of lots and date or complete measuring results, into a marking layout with network connection or via a serial interface

Labels

Specially developed labels are ideal for fast and accurate laser marking.

At present the main applications are in the field of the automotive industry and theier supplier

Glass

Our laser can be used for marking the surface of glass as well as create 2 and 3 D Images in glass blocks.

A further processing method for marking of glass surface is engraving using a CO2 laser

Smart Cards Typical applications are marking of Smart Cards such as ID cards, phone cards for cellular phones and credit cards.

The possibilities of marking covers photos, text and/or barcodes

ICs

Rofins IC Markers generate characters at sizes precisely in accordance with the user's requirements

Ceramics

Industrial ceramics can be marked with an Nd:YAG or CO2 laser.

Plastics CO2 lasers produce marking results similar to hot embossing, where the marking becomes visible only by the shadow of the engraving.

One of the applications where this effect is desirable is the marking of audio and data CD-ROMs.

Medical components Tempering-markings of titanium and high-grade steel provide medical instruments and implants with durable markings.

Using the Data Matrix code available on the Star Mark and Power Line systems, it is also possible to compress large data volumes within a minimum of space

Metals All materials made in metal can be marked by laser. The output power of our laser systems range up to 130 Watt.

In combination with one of our standard handlings, or with a customized solution, a large variety of marking options is available

PCBs

CO2 markings usually alter the soldering mask on printed-circuit boards to produce a grey to white marking on the mask.

Day & Night Design

The marking of component parts in the day & night design process is one of the most demanding applications along with wafer marking

Keyboards

A special application in plastic marking is keyboard marking.

As many as three lasers are able to mark a keyboard at the same time, two on the top and one on the underside.

Deep marking

Deep marking and engraving are technologies based on the same procedural principle, laser-induced ablation through melting displacement and/or evaporation

Wafer Marking

Laser cutting of stents and micro tubes

Laser cutting of surgical instruments

Laser cutting and perforation of polymers
