Ultrashort-pulse laser processing

A quantum leap in laser micromachining—ultrashort-pulse laser processing

Our ultrashort-pulse femtosecond (USP-fs) laser processing is redefining the boundaries of microtechnology. By using femtosecond pulses, we are able to create surface structures, cuts, and holes with a level of quality that conventional methods cannot achieve.

Laser Micro-Cutting

Precision parts made from metals, precious metals and alloys: Maximum accuracy and minimal burr formation

We cut precision parts from a wide range of conceivable metals, precious metals and alloys from a material thickness of 0.005 mm to 3.0 mm. Our specialization enables us to cut parts with very low burr formation and maximum accuracy.

Depending on the part geometry and material properties, production tolerances of up to ±3 µm can be realized and verified by protocol. These include, for example, mechanical watch parts, spring elements, shielding plates, calibration masks, shims, shim rings and precision tube parts of all kinds, which are manufactured both as individual parts and in series production.

Laser Fine Cutting

Precision laser-cut parts made of metals, precious metals, copper, brass, etc., with high accuracy

We manufacture precision parts from a wide variety of metals, precious metals, and alloys, with dimensions ranging from approximately 0.1 mm to 3.0 mm. Our specialization enables us to produce blanks with minimal burr formation and the highest accuracy.

Depending on the part geometry and material properties, manufacturing tolerances of up to ±5 µm are achievable and can be verified via a certificate of conformity. This includes, for example, mechanical shielding plates, calibration masks, shims, adapter rings, and precision tube components of all kinds, which are manufactured both as individual parts and in series production.

Laser Fine Cutting

Laser Micro-Welding

Non-contact joining of metals and metal alloys with laser welding technology

The laser is the predestined tool for non-contact joining of metals and metal alloys. This means that components can be welded without distortion using spots or seams, even in places that are difficult to access. We process small parts with a tendency towards miniature in a working area of approx. 188 x 160 x 200 (in mm).

We produce prototypes and series for customers in the watchmaking industry, precision engineering, sensor technology, electronics, electrical engineering and medical technology, for example.

Laser Marking - Laser Engraving

Perfect markings thanks to laser marking and laser engraving

Whether laser marking or laser engraving: The laser is the perfect tool for marking almost all materials. Processing takes place without mechanical stress, which guarantees a permanent result.

We can precisely place logos, characters, images, consecutive serial numbers, scales, barcodes, QR codes and data matrix codes on your product. With the finest line widths from approx. 15 µm, we meet even the highest visual demands in the design of luxury goods such as mechanical watches and exclusive writing instruments.

Laser-marked premium labels

Forgery-proof premium labels according to individual templates

We produce forgery-proof premium labels for almost all areas according to our customers' individual designs. Special materials that can be marked with a laser are the starting material for the production of these high-quality, non-destructively removable high-performance labels.

Our security labels are characterized by very high resistance to temperature, climate and chemicals as well as extreme abrasion resistance.
Please do not confuse these with the labels from your laser printer!

Precision Stencils

Laser-cut metal stencils for industrial production

High-precision, laser-cut metal stencils are essential in the industrial production of electronic assemblies, especially SMD stencils for solder paste application. Depending on the customer's technical requirements, these stencils are usually produced as frameless metal sheets with perforations for a quick-release system.
