Advantages of Hydroforming for Aerospace Applications

Hydroforming is frequently and advantageously applied within the aerospace industry. The typically high complexity of aerospace components necessitates a fabrication technique that canaerospace-cap-edited-500x477 effectively produce the desired shapes and forms. Metal sheet hydroforming provides an economical manufacturing solution for parts with asymmetrical or complex geometries and irregular contours as the process requires fewer passes to produce the desired part than a comparable matched die stamping process.

The Versatility of Metal Spinning and Hydroforming

An extremely versatile technique dating back to ancient times, metal spinning — also known as metal turning or spin forming — allows ductile metal to be formed into different shapes by rotating it on a spindle. 

Hydroforming is also utilized to form metal into varying shapes. The main difference with hydroforming is that it uses pressurized hydraulic fluids to shape a flat metal disc.

Without removing any of the material, and thereby keeping the metal strong, these process can turn malleable metals into high-performance parts for a wide range of applications and industries.
