Custom Spun Metal and Metal Spinning


Introduction to Metal Spinning

Metal Spinning is also known as spin forming. It is a process where a tube or a disc of metal is rotated at a high speed, and is transformed into an axially symmetrical object. Metal spinning is usually done using a vertical or horizontal lathe.  This process can be performed using cnc, hydraulic power or by hand.

Applications of Spun Metal

Spun metal is used to create round metal parts. This has many commercial applications such as creating decorative and architectural parts. Apart from this, spun metal is also used in machinery parts, cookware, gas cylinders and brass instruments.

Metal spinning can be performed on any ductile metal, such as aluminum, stainless steel, copper, brass and carbon steel. The diameter and the depth of this spun metal can be of various sizes. The advantages of metal spinning include the ability to create objects seamlessly  by using a single piece of material and low cost tooling in respect to alternative forming methods.

CNC Metal Spinning & Tooling

At Helander, we use advanced CNC, power assisted and manual forming to create our custom spun metal components. We can spin parts up to 36 inches between centers. Our metal spinning equipment can create parts that measure up to 100 inches in diameter. Our machinery can handle a material thickness of up to 0.250 of an inch for stainless steel, 0.375 of an inch for carbon steel, and 0.750 of an inch in aluminum.  We also offer in house tooling.

Our metal spinning services adhere to strict high industry standards. Our spun metal has found applications that range from decorative to medical parts in both small and large sizes and production volumes.
