Metal Tank Heads Spinning

Metal tank heads are critical components used in various industries, including automotive, aerospace, chemical, and pharmaceutical. These tank heads, also known as dished ends or pressure vessel heads, are responsible for sealing the ends of cylindrical tanks, pressure vessels, and pipes. While there are several methods to manufacture tank heads, metal spinning stands out for its ability to produce seamless, precise, and strong tank heads.

Metal tank heads spinning is a specialized form of metal spinning that focuses on creating dished or hemispherical shapes to serve as tank heads. This process involves the use of a spinning lathe or CNC spinning machine, where a flat metal disc or sheet is gradually formed into a tank head shape by applying pressure and spinning it against a mold or mandrel.

The spinning process starts with a flat metal blank, typically made of materials like stainless steel, aluminum, or carbon steel. 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 spherical or dished mold. This gradual forming process ensures that the metal stretches uniformly, resulting in a seamless and precise tank head.
