About us

We design and manufacture structural technical parts for transportation systems. We obtain significant mass savings in order to reduce the propulsion energy consumption of trains, boats, planes and automobiles. We innovate by manufacturing aluminum honeycomb sandwich parts with complex double-curved shapes.

Our expertise

Aluminum offers a wide variety of alloys with different mechanical characteristics. Halcyon’s expertise lies in choosing the right alloy for the application in question. Likewise, we define the thicknesses of the sheets and honeycomb in order to obtain the best compromise between mechanical specifications and mass savings.

We handle prototyping or complete production line projects. We offer fully equipped solutions, with inserts for example, to guarantee the longevity of our products.

Halcyon is an ideal partner for developing your products, due to our responsiveness and experience.
