The front grille for the BMW iX is produced in a cleanroom environment, since any dust would be visible through the high-gloss polyurethane (PUR) finish. Produced in an integrated process, the component consists of a functional film that is back-injection moulded with polycarbonate (PC) and then flood-coated with 2-3 mm PUR. Engel developed the production cell.

Cross-section through the detachable roof modules of the Ford Bronco. This part is made with a thermoformed thermoplastic outer layer, which is back-moulded with glass fibre and polyurethane resin (PUR), plus a Nomex honeycomb core for increased thickness (stiffness with minimal additional weight). It is manufactured by compression moulding, whereby the thermoformed polycarbonate (PC) is placed into the mould, onto which glass fibre and honeycomb are laid. A precise dose of PUR is applied by spraying on the layers and then the whole assembly is compressed in a mould and heated to cure.

Reusable cup injection moulded in polycarbonate (PC).

Aircraft glazing consists of a combination of laminated strengthened glass and plastic, including stretched cast acrylic, polycarbonate (PC) and polyvinyl butyral (PVB) laminating film. The aluminium fuselage is coated with polyurethane resin (PUR).
