How to Design Parts for Metal Spinning

Metal spinning is a unique and versatile manufacturing process that can create a wide range of parts and components. However, designing parts for metal spinning requires careful consideration of certain factors to ensure success. In this blog post, we’ll provide you with a comprehensive guide on how to design parts for metal spinning.

Material Selection

The first step in designing parts for metal spinning is selecting the right material. The material you choose will affect the cost, durability, and quality of the final product. You must choose a material that can be formed through the metal spinning process, such as aluminium, brass, copper, or stainless steel. For a more comprehensive list of materials and their uses, check out our blog post on “What Metals are Used in Metal Spinning?”

Shape and Size

Before you begin designing your part, consider the shape and size requirements. Metal spinning can create parts with a wide variety of shapes and sizes, but the process has some limitations. Understanding these limitations will ensure your design can be made through metal spinning. For example, some complex shapes may require specialized or multiple tooling as well as secondary services such as welding to achieve the desired result.


Tolerance is the allowable variation in a part’s dimensions. The metal spinning process typically allows for high tolerances, which means the final product can be very precise. However, it’s still crucial to determine the tolerance required for your part to ensure the final product meets your specifications. The tolerance may vary depending on the customer requirements and the specific metal spinning method used, so be sure to discuss this with your metal spinning provider.

Wall Thickness

It’s important to keep in mind that the material’s thickness affects its formability. Additionally, wall thickness has an impact on the tolerance and intricacy of the design. If you need high precision or intricate designs, thinner walls may be necessary. Our team can work with you to determine the optimal wall thickness for your project, taking into account both formability and design requirements.

Incorporate Features

Metal spinning can create various features, including flanges, holes, and threads. Incorporating these features into your design can increase the part’s functionality and improve its overall performance. It’s essential to consider how these features will affect the metal spinning process and ensure they can be accurately formed. Metal spinning can also be a one-stop solution for creating complex components that would otherwise require multiple manufacturing processes.

Optimize for Manufacturing

The final step in designing parts for metal spinning is to optimize the design for manufacturing. This includes considering the process steps, material handling, and tooling requirements. Optimizing for manufacturing can reduce costs, shorten lead times, and improve the overall quality of the final product.
