JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
The group presented its latest developments around plastics joining, thermoforming, and PU processing technologies as part of the Fakuma trade fair show.
Plastics joining – IR welding machine with new camera control systemFrimo has added two new design sizes to its portfolio of standardized infrared welding systems in the JoinLine IR welding machine series. In addition to the IR-V-ECO-1200 with a maximum clamping area of 1200 x 600 mm, they presented the JoinLine IR-V-ECO-800 (800 x 450 mm). The two models, each with up to 24 heating circuits, fill the gap between the models 500 and 1600 that have been available until now.The JoinLine IR systems are specially designed for frequent and thus extra speedy tool changes. A tool change can take less than five minutes, during which it is not necessary to cool off or preheat the tool. A high-performance drive system allows for increased productivity with view to the critical phase of changeover time and joining after heating and at the same time guarantees a high level of joining precision.The JoinLine IR-V-ECO-800 can be equipped with an innovative thermal imaging system for inline process monitoring and consistent documentation of welding parameters. Compared to conventional products this newly presented infrared camera system is smaller and also stands out from the rest through its high level of user-friendliness and measuring precision. By monitoring the necessary temperature distribution during the welding process, a consistently high level of welding quality and process reliability can be achieved.Thermoforming - High-class surfaces in foilThe high quality look of surfaces plays an important role in the design of modern automotive interiors. The trend towards an ever increasing variety of different designs and materials in numerous combinations necessitates that suitable modifications and advances are made to processing technologies. For producing decorative surfaces, foils possess diverse properties that make them attractive and economical.
In order to minimize foil consumption, the company has developed foil cut optimization, which allows the foil separating cut executed when changing rolls or colors to be set in such a way that the resulting foil waste is minimized and no unusable components are produced. Foil edges are manually cut and automatically welded together using an ultrasonic device. An intelligent machine controller records the number of strokes as well as the feed length and is thus able to determine the optimal positioning for the foil joining line immediately before or after the clamping frame.Lightweight Construction for mass production with HP RTMHigh pressure resin transfer molding (HP RTM) is increasing in importance for serial production of structural components made of fiber composite plastics. On the HP RTM dosing unit from FRIMO (EPOx Mix and PURe Mix), epoxy resins as well as polyurethane can be processed in combination with endless-filament reinforcement to form high-performance fiber composite components. The Institute for Lightweight Construction and Plastics Technology (ILK) at the TU Dresden has just recently commissioned two high-pressure resin transfer molding (HP RTM) dosing units from Frimo in order to expand its development and service offerings. One of the machines is equipped for an output range of 33 to 166 g/s with epoxide matrix material and the second machine for a range from 10 to 65 g/s with polyurethane matrix material.
