Spinning, Stamping, and Hydroforming: Which Works Best for Your Application?

Most manufacturers consider metal spinning, metal stamping, and hydroforming to be specialized and narrowly focused processes, but actually, these metal-forming methods are used in industries as varied as commercial construction, interior design, heating and climate control, and agriculture. Manufacturers use spinning, stamping, and hydroforming methods for products ranging from satellite dishes to funeral urns.

Understanding the benefits of each process as well as where they overlap will help you decide which metal forming technique best suits your application. Below, we’ve assembled an overview of the three main metal forming practices, and we also outline the ways they could benefit your production line.

 

Metal Spinning

Metal spinning produces hollow parts in typically circular cross sections. This low-cost process efficiently allows you to create large volumes of cylindrical objects with minimal waste, and its tooling’s innovative design allows you to make changes to the production process at minimal expense.

Metal spinning can create objects with diameters ranging from one inch to eight feet. Manufacturers use metal spinning to build products including roofing, lighting, stainless steel bowls, engine components, musical instruments, brass vases, and satellite dishes.

Metal Stamping

Metal stamping uses precast dies to form flat metal sheets into different shapes. Because metal stamping requires less machine use and fewer laborers, it incurs fewer production expenses than other techniques.

Well-designed metal presses can punch, bend, notch, and emboss sheet materials as needed. Parts formed via metal stamping often appear in farm equipment, brackets, caps, and ventilation systems as well as many other industries.

Hydroforming

Hydroforming uses oil pressure to shape cold-forming metals such as aluminum and stainless steel into durable, yet lightweight, pieces. The seamlessly bonded end products feature a high stiffness-to-weight ratio, so they meet the required tightness tolerances. 

This cost-effective method creates components via single-stage production, which also makes it easier to process large amounts of material at a time. Metal formers use hydroforming to build lighting fixtures, satellite antennae, and a wide range of automobile parts.

Which Method Best Fits Your Application?

Each metal forming technique offers unique benefits and drawbacks depending on its application. Manufacturers must also take their desired volume sizes into account when selecting a metal forming method. 

  • Metal spinning works best for prototyping and parts with high internal and external pressure
  • Metal stamping quickly fills both low- and high-volume orders and precisely cuts complex shapes
  • Hydroforming produces large, complex parts that require original finish maintenance, and can yield annual volume runs both large and small
