Pressler Hot Gas Expansion Formed Tubes

Pressler independently innovates and develops a 2D blank bending generation algorithm for 3D tubes, achieving continuous and stable feeding of blank tubes on traditional roller hearth heating furnaces. The entire process requires no pallet auxiliary support, greatly improving production efficiency. The entire technology is independently developed by Pressler with complete independent intellectual property rights.

Compared with conventional automotive hot-formed parts, hot-formed tubes are superior in lightweighting, structural strength and stiffness, with excellent anti-deformation capability in automotive door collisions.
