Hydroforming: When Water Power Makes New Products Possible
2,000 bar and more – pressures far beyond those of conventional forming processes. For HAPPICH GmbH they are the key to a technology that already demonstrates what product development of the future looks like today: sheet-Hydroforming as a platform for innovative, functional, and sustainable new products.
In hydroforming, sheet metal is precisely pressed against the contour of a tool using extreme water pressure. Unlike conventional deep drawing, only a single tool half is required. This reduces tooling effort, increases process stability, and opens up enormous freedom in geometry. Complex shapes, small radii, smooth transitions, and great component depths can be realized with a high level of repeatability.
The real added value, however, lies in the interaction between form and function. Through targeted geometry – such as beads, material flow paths, or reinforcement zones – strength, stiffness, and load-bearing capacity can be precisely adjusted. This enables:
- Lightweight design without compromising stability
- Material savings, resulting in lower costs and an improved CO₂ footprint
- Functional integration where multiple components were previously required
- Reduction of weld seams and joints, increasing component service life
HAPPICH not only masters the forming process itself but the entire value chain: from blank design and high-precision toolmaking to downstream processing and finishing. Especially in sheet hydroforming, this expertise is crucial, as empirical values can only be transferred to a limited extent. Every new component represents a piece of development work – and this is exactly where Happich’s strength lies.
Hydroforming is suitable for a wide range of materials such as stainless steel, aluminum, or steel sheet and can be used across many industries: from vehicle and mechanical engineering to protective and structural components, as well as sophisticated design parts with visible surfaces. Even sensitive, brushed sheet metals usually withstand the forming process without surface damage.
Looking ahead, hydroforming at Happich is being consistently advanced: digital simulation, data-driven process optimization, new material combinations, and functionally integrated components open up enormous potential for new products. For customers, this means fewer parts, better performance, shorter development times – and solutions that clearly stand out from the competition.
HAPPICH hydroforming therefore stands for more than just a manufacturing process. It is a tool for innovation – driving progress forward under high pressure.
