The trainees from the companies Canto, HASCO, Klaucke & Meigies, Kostal, Lauer Harz and Pakulla, who are participating in the "Toolmakers' Talents" (TomaTa) project have a period of two years to complete the overall design, production and sampling of an injection mould that is suitable for use in production.
The trainees have been able to bring the fifth project phase to a close with the completion of the injection mould. The elaborately designed mobile phone holder, which can charge smartphones directly in the socket, has repeatedly confronted them with particular challenges. High thermal and mechanical loads made it necessary to use a plastic that was demanding to process. Employing HASCO standard parts and hot-runner components, it proved possible to successfully implement all the requirements set out in the specifications for manufacturing the mould.
The intercompany cooperation of the teams proved stimulating. The trainees initially divided up the processing of the mould components and then performed the work in their individual companies. In addition to the working meetings, coordination within the TomaTa team took place via a live mould-construction blog. This was where the process was digitally documented.
Once the individual mould components had been completed, the competence team met up in the HASCO Learning Center for a trial assembly of the mould. They then defined the subsequent required work steps to put the "finishing touches" to the individual mould parts. Over the days that followed, the HASCO training workshop became the command centre for the TomaTa mould project. It was from here that the team coordinated the next stages of work in the individual company workshops. That was where the fine tuning was carried out – deburring, adjustment, polishing, laser engraving of the elements, checks on cooling circuits and measuring and bedding down the mould halves.
At the end of this project phase, the complete mould, with all its components, had been successfully finished. The final project phase now promises to be an exciting one. This will show whether the trainees have succeeded in mastering one of the main tasks of the project – the correction of deliberately introduced process and mould errors. The trainees are now going to sample the injection mould at the Plastics Institute employing the K-Advisor software. The project, which is partially funded by the state of North Rhine-Westphalia and the European Social Fund, is ending in autumn 2019.
