The Trumpf Group’s Laser and System Technology unit has taken a high-tech approach to elevating the value of brake discs by promising to reduce the degradation that occurs with normal use, and more specifically to reduce the particulate matter that results from disc brakes wearing down. The new approach is laser deposition, and the results are being evaluated in series production with some automotive manufacturers and suppliers.

“As a technologically leading laser system manufacturer, we have been working closely with the automotive industry for years and know the market very well,” says Richard Bannmüller, president and CEO of Trumpf Laser and System Technology. “High-speed laser metal deposition is cost-effective, can be used in series production and thus offers the potential to become the new standard in brake disc manufacturing.”

Energy efficiency. Laser cladding works through a complex interaction between laser and metal powder, making it possible to create pore- and crack-free layers. The key to the process is the powder and energy input. Instead of applying the metal powder to the component and then melting it there by laser light, in high-speed laser buildup welding the metal powder enters the laser beam just above the component. The light heats the powder to melting temperature even as it is being delivered to the component surface. This makes it possible for brake manufacturers to apply the coating much faster and to use the energy employed much more efficiently to form the layer.

Instead of applying the metal powder to the component and then melting it there by laser light, in high-speed laser buildup the material enters the laser beam just above the component. The laser-deposition process not only ensures less fine dust is produced from the brakes while in service, but also less wear, and the market potential for that is huge. German automakers produce around 3.4 million cars/year, and for the roughly 49 million cars already on the market in Germany drivers have had to replace their brake discs several times, often after just 50 000 km, depending on driving style and wear. Laser deposition could mean these replacements could be necessary much less frequently. 压铸展-铸造展-2024第二十四届广州国际压铸、铸造及工业炉展览会-巨浪展览-The 24th Guangzhou Die-casting, Foundry & Industry Furnace Exhibition 2024压铸展，2024压铸展会，2024压铸展览会，2024铸造展，2024铸造展会，2024铸造展览会，2024广州压铸展，2024广州压铸展会，2024广州压铸展，2024广州铸造展会，广东铸造展，中国铸造展会，广东铸造展，中国铸造展会，2024有色铸造展会，2024压铸展展会信息，2024铸造博览会，2024压铸博览会，2024压铸机展，2024压铸机展会 2024铸造设备展-Die-casting Industry Exhibition,Die-casting expo, 2024 Die-casting exhibition, 2024 Die-casting expo, China Die-casting exhibition, China Die-casting expo,Die-casting Industry event,Die-casting event, 2024 Die-casting event,Die-casting event 2024, China Die-casting event, China Die-casting event,foundry Industry Exhibition,foundry expo, 2024 Die-casting exhibition, 2024 foundry expo, China foundry exhibition, China foundry expo,foundry Industry event,foundry event, 2024 foundry event,foundry event 2024, China foundry event, China foundry event
