Tool making We stick to the "single source supply" principle. Marchtrenk is not only the center for the development of products. Here we design and produce the molds for injection molding products exclusively in our own tool making department. Our expertise is concentrated entirely here at our HQ. This makes us independent and we can react in a flexible manner. You do not have to worry whether your tool has been calibrated properly to produce good components – we do that for you. We supply you with perfect silicone or compound parts.
