Large systems for automotive speaker grilles The production of automotive speaker grilles follows its own rules. The parts must feature a high mechanical stability, the design of the fine grille structure has to be specifically adapted to the interior of the car to achieve a perfect acoustic pattern and all visible surfaces have to be flawless with a pleasant feel. The typical materials used are POM, PC-ABS or PA6-ASC blends. The percentage of multicomponent applications is steadily growing. One of the few companies which have specialised in the production of these demanding parts is Bernd...
