Dies are made of tool steels that are super-hard and abrasion-resistant. This makes them suitable for shaping other materials, like aluminium.
At Hydro, we make our own dies. We also buy dies from independent toolmakers. We develop design aids for effective extrusion die design, we correct dies to optimize productivity and we research die performance. We keep improving the production process to reduce costs for you, using:
Medium and large-sized extrusions are pressed through a die with only one opening. Smaller extrusions can be pressed through multi-aperture dies – with as many as 16 apertures.
