technology. The demonstration part had a wall thick- ness of just 0.6mm. The highly automated production cell operating on Engel’s exhibition stand (and also scheduled to run at JEC World 2017 in March) was specially designed for the combination of Tepex preforms and IMD films. It integrated three processing technologies: Engel Organomelt for shaping and functionalising the preforms in the injection moulding process; Engel Variomelt for optimising the surface quality via variothermal mould temperature control; and IMD for optical and functional surface finishing directly in the mould. The heart of the cell was an Engel insert 500V/130
single injection moulding machine with a roll-to- roll IMD unit, an Engel Easix six-axis robot for part han- dling, and an infrared oven also developed and built by Engel for preheating the thermoplastic fabrics. This made it possible to form, over-mould and decorate the preform in a single step. Robot and oven control were all fully integrated into the CC300 control unit of the injection moulding machine. Engel has developed five oven sizes with a heating surface areas up to 1,110mm by 1,610 mm, which makes it possible to process large
