The Importance of Bridge Design in Extrusion Dies
In bridge-type extrusion dies, bridge geometry directly affects metal flow, die life, and product quality. Studies using FEM (Finite Element Method) simulations show that curved bridge designs provide more balanced flow, lower stress, reduced die deformation, and lower press loads.
Compared to sharp-cornered bridge designs, radius and streamlined bridge geometries make the extrusion process more efficient and sustainable.
Conclusion: Proper bridge design not only improves profile quality but also enhances die longevity, production efficiency, and process reliability.
