In the development of new manufacturing solutions, the combination of different technologies and the integration of different work steps into the process play a key role. With the Organo Sheet Injection (OSI) process, the company Frimo offers now a new way to combine forming and back injection in a single operation. As a result, the previously separate work steps of hot pressing bar-shaped semi-finished products and subsequent back injection can now be integrated into one process. Combining the processing steps not only reduces the cycle time but also saves considerably on mould costs. Handling and storage costs are also reduced.
Having been pre-heated in the injection mould, the large surface area semi-finished products, whether made, for example, of NFPP (natural fibre + PP) or organo sheet (CF, GF, aramid mesh/mat with different thermoplastic matrices), are first formed and then they are back injected immediately thereafter. This back injection process can integrate functions such as fixation eyelets or specifically placed reinforcement ribs and also enhance the quality of component edges.
In order to persuade customers of the results which can be achieved with the Organo Sheet Injection process, the company has set up a neutral test mould to produce sample parts. As an example of application, samples of a window retainer can be produced with NFPP and also with various organo sheets.
