Solutions The laser - that much became clear very quickly - is the tool that can optimally meet Miethke's many challenges. Black marking proved to be ideal as a concrete procedure. This is due to the fact that the extreme peak pulse power changes only the surface structure, and there is no material ablation. As processing is contact-free with only a small heat-affected zone, the component does not change its shape and its metallic structure remains virtually unchanged. This retains the biocompatibility of the titanium. Black marking creates deep-black, high-contrast markings on Miethke valves, such as the implant's direction in the form of an arrow, which remains legible even under highly reflective surgery lamps. Miethke utilises the ultrashort pulses of the TRUMPF marking lasers not just for marking, but also for laser precision cutting of the valve's microtechnology components. The company has found the ideal solution for both production tasks in the TruMicro Mark.
Implementation "A dialogue between equal partners" – is how Miethke summarises the partnership with TRUMPF. An application engineer from TRUMPF together with Miethke "tinkered" in the Laser Application Centre (LAC) in Ditzingen until they found the perfect sample part and the optimum process. During this phase, the TRUMPF application engineer passed on a great deal of helpful expertise to Miethke, which the company can use to further develop and optimise processes by itself in the future. Furthermore, TRUMPF also visited the customer in its in-house application lab for laser fine tuning and for detailed parameter setting.
Forecast The collaboration, the trust, and the knowledge that TRUMPF technology is not a "flash in the pan" – reason enough for Miethke to say, "Okay, TRUMPF could be the partner for the future, and that is exactly what happened." The medical technology manufacturer aims to produce top quality in the long-term. This is why, by their own account, the decision makers knew that quality had to be the decisive factor in the purchase. Futhermore, the Potsdam-based company believes that TRUMPF is a pace setter with the ability to grow with the future requirements in medical technology and to drive the development of Miethke's portfolio with new technologies. In future the company would like to integrate data processing for the marking process, for example. TRUMPF is already offering solutions for this and continues to develop them further in order to satisfy customer requirements in the best possible way.
