françaisIn the recently completed European Regional Development Fund (ERDF) research project "Scan Cutting", scientists from the Fraunhofer Institute for Laser Technology (ILT) have developed an amazing new technology for contact stamping technology-for laser Hybrid manufacturing process for cutting thin-walled metal strips. The researchers said that even the most precise parts of the contact parts, this process can be manufactured in an environmentally friendly, high-precision and efficient way.
The plug connectors are small and unobtrusive at first glance, but modern cars cannot operate without them. Thousands of plug connectors transmit signal and control voltage from one part of the vehicle to another. Currently, these contact parts are produced using traditional stamping and bending processes. However, the ever-increasing number of automotive connector components is pushing this established mechanical method to the limit. As the miniaturization trend continues, the demand for micro plug connectors with contact components is increasing sharply, and the structure of the contact components becomes more and more sophisticated.
In this context, laser cutting opens the door to previously impossible design solutions, especially when it comes to creating several independent contact points in a tiny installation space. In this case, multiple contact points allow even the smallest contact system to provide a reliable electrical design, which is very important for reliable signal transmission.
The researchers also combined augers with ultrashort pulse (USP) lasers. This patented method developed by the Fraunhofer Institute for Laser Technology has proven to be an excellent choice for drilling high aspect ratio precision micro-holes in steel, glass and ceramics.
