Laser-based repair of structured molds
Project duration: 1. November 2015 – 31. October 2018
Plastic injection molding is one of the most cost-effective manufacturing technologies for large-scale production. Therefore, molds and mold inserts are the most important components as they are responsible for the quality and efficiency of the final products. Finely structured surfaces are applied to the molds in order to give a special product design or functionality to the final plastic part. Grained plastic parts are used in the automobile industry, for instance, where they can be found in dashboards or impact absorbers. During the plastic injection process, wear can occur by using fiber-reinforced plastic material or damages are caused due to wrong handling. In this case, repair is hardly possible these days or it requires a high amount of manual effort. This is a disadvantage for the manufacturing company as it leads to new time-consuming and costly purchases, long repair times or even production stop. In the project “ToolRep” (contract no. 02P14A032), which is funded by the German Federal Ministry of Education and Research (BMBF), Fraunhofer IPT and the Institute for Optical Systems Konstanz as well as four industrial partners jointly develop a holistic repair solution.
