Inline marking via micro-heaters in the mould insert
An electric ALLROUNDER 570 A in clean-room version produces four auto-injector housings in a cycle time of around eleven seconds. The high-performance machine from the ALLDRIVE series is predestined for fast and precise serial production of medical technology products and fulfils the requirements for production in ISO 7 clean-room class. The 4-cavity mould is based on the proven Kebo “Lift & Strip” concept and is actuated completely mechanically and synchronously via the machine ejector. The highlight of the application is a dynamic mould insert integrated into the cavities, through which each component receives an individual Data Matrix code. The insert is equipped with 144 individually controllable micro-heaters, which reach temperature within milliseconds and generate individual geometric structures. Each micro-heater measures only 0.28 x 0.28 millimetres and weighs only around 0.0000015 grams (1.5 micrograms), making it 20,000 times lighter than a grain of rice. Subsequent production steps are unnecessary. This reduces cycle time, installation area and the costs of an additional marking device and robot system for part handling.
