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 of a foam sandwich injection moulding. The white outer is virgin polypropylene (PP) and the black core is foamed recycled PP (rPP). The layers are formed by first injecting the white (the colour has been used to emphasis the technology in this case) and then injecting the black with chemical foaming agent (CO2). The black rPP forms a bubble inside the white, pushing into onto the surface of the mould. In application, the surface layer would be the same colour as the core to create a high quality visual surface. This example is a cross-section through the LimbicLife ergonomic chair seat. The process and tooling were engineering and optimised by Deckerform.

Renault interior door panel made with LYB LyondelBasell polypropylene (PP) with a chemical foaming agent added to produce a foamed part. This approach helps to save 15-20% weight. The texture is designed to eliminate the need for a covering, to save cost and ensure the part can be recycled end of life.

Renault A pillar interior trim made with LYB LyondelBasell polypropylene copolymer (PPC). A special effect compound is added to create the speckled appearance in combination with moulded textile texture, eliminating the need for covering.
