Connecting Panel for Refrigerated Counter

Hydroforming of Sheet Metal for Professional Refrigeration Systems

Hydroforming offers surprising advantages for those using medium- and large-sized stamped sheet metal components, especially when working with thin-gauge stainless steel.

This technology significantly increases the mechanical stability and rigidity of the formed sheet, thanks to the widespread work hardening of the raw material. As a result, the component remains flat and is almost entirely free from the springback effect typical of traditional stamping. Additionally, the surface finish is noticeably superior and aesthetically appealing after forming.

The Challenge and Customer Requirements

A prime example is a leading manufacturer of refrigeration systems who turned to Inoxveneta for the production of a stamped connecting panel between two refrigerated counters. The project posed several challenges: a length of nearly 2 meters, a complex and asymmetrical shape, and a depth of 10 cm. The final component also had to ensure easy installation (without any springback), offer an excellent surface finish, and meet a relatively low tooling investment budget.

The Solution: Hydroforming

Within just a few weeks, thanks to Inoxveneta’s support in co-designing the component, the hydroforming die and the first prototypes were completed — fully meeting the project’s requirements and at a highly competitive cost. The panel has since gone into regular production with full customer satisfaction. In 2014, a new version of the hydroformed panel was commissioned to complement the first model.
