3D laser processing (BLS)

The sister company BLS Lasertechnology GmbH also offers laser material processing of 3D parts. As a long-standing partner to industry for complex and technologically sophisticated laser applications, BLS offers laser material processing at the highest level. The company supports customers from various industries and offers all essential processes for the laser processing of 3D metal components.

High-precision joining of various (non-ferrous) metals with a focused, computer-controlled laser beam. The welding depth of 0.50 mm to 12.00 mm and a minimum diameter of approx. 0.5 mm guarantee precise and high-quality results with high repeat accuracy.

Targeted melting and insertion of a metallic powder using a laser beam enables the application of firmly welded layers of 0.01 to 1.5 mm per process. The efficient process enables 3D laser printing of metal, is computer-controlled and makes it possible to combine different materials.

Precise and efficient cutting of various materials with material thicknesses from 0.3 mm to 10.00 mm. In addition to high repeat accuracy, the process impresses with high process speed and the best possible burr-free contours.

A focused laser beam heats the workpiece at the desired location. The heat input changes the carbon atoms in the material, austenitization takes place and the treated layer hardens. The automated CNC control of the laser ensures maximum precision and excellent quality at process speeds of 10 to 150 cm/min.

3D laser welding

Laser welding is a technologically leading welding process for joining various metals and/or non-ferrous metals. A focused laser beam is used to join different (non-ferrous) metals with a welding depth of 0.50 mm to 12.00 mm. The automated and precise welding process enables low-distortion weld seams with a minimum diameter of approx. 0.50 mm. The use of CNC-controlled machines achieves a high repeat accuracy of ±0.01 mm in series production. BLS Lasertechnology offers all common laser welding processes and will be happy to advise you on the right process for you.

Joining components using laser welding offers extensive advantages. It can be used for various materials such as aluminum, stainless steel, copper, titanium and material alloys, usually without additives. Individual geometries can also be realized. Laser welding is scalable and reliably delivers high-quality results with low thermal influences.

Laser metal deposition (LMD)

Laser metal deposition (LMD) is a modern additive laser process that enables 3D laser printing of metal. The laser melts the component surface and applies metallic powder, creating form-fitting layers of 0.01 mm to 1.50 mm. The process is used to repair high-quality components and to protect against wear and corrosion.

Laser metal deposition is efficient, individual and suitable for a wide range of materials. In addition to raw materials such as copper, cobalt or titanium, special material combinations can also be produced. For example, joining nickel with tungsten carbide by precisely applying thin layers ensures a high level of wear protection for your components. Automated laser guidance ensures the highest quality and precision. The ability to combine materials with different premises in particular enables a high degree of flexibility in the use of materials.

3D laser cutting

BLS Lasertechnology has stood for high precision in complex three-dimensional geometries with difficult-to-access areas and tight tolerances for over 35 years. The efficient and contactless cutting process enables the virtually burr-free cutting of various materials with material thicknesses of up to 10.00 mm. The surface of the material is heated by the focused laser beam and sublimates or vaporizes as a result.

The fully automated and computer-controlled guidance of the laser beam enables high repeat accuracy with low thermal influence. Minimal waste and a high process speed also mean that the process can be used economically. This makes the cutting process suitable for small, medium and large batch sizes. The wide range of materials that can be cut includes metals and their alloys, special materials and plastics.

Laser hardening

Laser hardening is a flexible process for the targeted and precise hardening of metallic components. The focused laser beam heats the focused area of the component to a hardening depth of 0.50 mm. As a result, the microstructure is transformed into martensite, which increases the wear resistance and raises the hardness value to the maximum limit. The process utilizes the self-quenching of the material by dissipating heat into the interior of the component.

Laser hardening is suitable for carbon-containing metals with a carbon content of at least 0.20%. Thanks to the CNC-controlled laser beam, heat is applied precisely and at a high process speed of 10 to 150 cm/min. This minimizes deformation and reworking.
