Metal Dish-Shaped Spinning

Metal dish-shaped components, commonly referred to as dished ends or tank heads, are vital elements in various industries such as chemical processing, food and beverage, pharmaceuticals, and aerospace. These dish-shaped forms serve as end caps for cylindrical vessels, ensuring structural integrity and performance under varying pressures and conditions. Metal spinning, with its capability to produce seamless and precise dish-shaped components, has emerged as a preferred method for manufacturing these crucial elements.

Metal dish-shaped spinning is a specialized form of metal spinning that focuses on creating dished or hemispherical shapes, often referred to as tank heads or dished ends. This process involves using a spinning lathe or CNC spinning machine to shape a flat metal disc or sheet into a dish-shaped component by spinning it against a concave mold or mandrel.

The spinning process begins 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. Specialized tools and rollers then apply pressure to shape the metal around a concave mold or mandrel, gradually forming it into a dish-shaped or hemispherical form. This controlled forming process ensures uniform stretching of the metal, resulting in a seamless and precise dish-shaped component.
