Metal Venturi Spinning

Metal Venturis, also known as Venturi tubes or Venturi flow meters, are essential components in fluid dynamics and fluid measurement systems. Named after the Italian physicist Giovanni Battista Venturi, these devices utilize the Venturi effect to measure fluid flow rates or create a vacuum by accelerating fluid through a constricted section. The precise and intricate design of Venturi tubes requires advanced manufacturing techniques, and metal spinning has emerged as a preferred method for crafting these complex shapes.

Metal Venturi spinning is a specialized form of metal spinning that focuses on crafting Venturi tubes or Venturi-shaped components used in fluid dynamics applications. This process involves using a spinning lathe or CNC spinning machine to shape a flat metal disc or sheet into a Venturi profile by spinning it against a specially designed mold or mandrel.

The spinning process begins with a flat metal blank, typically made from materials like stainless steel, aluminum, or brass. The blank is clamped onto the spinning machine, which rotates it at high speed. As the machine spins, specialized tools and rollers apply pressure to shape the metal around a Venturi-shaped mold or mandrel. This controlled forming process ensures uniform stretching of the metal, resulting in a seamless and precise Venturi component.
