Brochure Application Center Laser Structuring for Tool and Mold Construction

Using laser radiation to ablate material for the purpose of shaping and structuring tools and molds has become an established process with a wide range of uses. At the Fraunhofer Institute for Laser Technology ILT, experts are continuously improving the quality of surface results through the use of ultrashort laser pulses (USP). The melt-free structuring of ultra-hard materials is a main focus of our work.

In the application center for laser structuring, we develop and evaluate new laser technologies for the production of tools and functional structures. Where conventional manufacturing techniques such as milling and EDM come up against their commercial or technological limits, laser processing offers productive solutions with structural resolutions in the micrometer range and accuracies in the nanometer range. From feasibility tests to small batch production, we accompany you on your road to using this innovative tool. Components for prototypes or small-scale series can also be produced cost-effectively in multiple parts panels.

Applications

  • Light guide structures in forming tools
  • Finely roughened (black) surfaces on steel for high contrast in injection-molded parts (barcodes and matrix codes)
  • Structuring, cutting and drilling ceramics
  • Design structures on freeform surfaces
  • High-speed drilling of thin films
  • High-precision drilling with adapted cone

Machinery

Fraunhofer ILT’s inventory of ultrafast pulsed lasers and laser machines is the only one of its kind in Europe. For special tasks for which there is no existing solution, we build special optics and handling systems, such as immersion optics for the internal structuring of cylinders to minimize friction.

Range of Services

Following your specifications, we create tools and tool inserts with micro- and nano-structures in all common tool materials, such as through-hardened tool steel. Based on CAD data (IGES, STEP, etc.), we transform your design ideas into real tools and surfaces.

Should unknown properties of a material or the demand for special geometries prevent us from manufacturing a tool directly, we can use special processes we have developed to determine the relevant manufacturing parameters. Together with external partners specialized in tool and plastics technology, we can also model the entire process chain of a productive manufacturing operation for you.

Send us a non-binding request for a quote and we will draw up a detailed offer. If you approve, we will carry out the work in a development and manufacturing environment certified to ISO 9001/2008.

We look forward to hearing from you!
