Or, in other words, they're injection molding the trim pieces for the pillars right onto the back of fabrics.

Injection molding for interiors--including fabrics: plenty of interior components are injection molded. But some companies--such as VW--are using a process for trim pieces that both mold a component and cover it in fabric in a single molding process. And it is coming to the U.S. in the not-too-distant future

At its 23rd International Plastics Colloquium this spring, the IKV (which stands for the German equivalent of Institute for Plastics Processing) presented the latest results of injection molding research projects on computer simulation of micro-molding, ultrasonic analysis of sink marks during molding, and alternative techniques to improve surface quality of foamed parts.
