The process of metal spinning is also often referred to as spin forming. This is a metal working process that is commonly used for producing metal objects that are round, cylindrical or spherical in shape. There are several different types of metals that can be used for making spun metal. These include stainless steel (series 300 and 400), carbon steels, aluminum, copper, bronze, and brass apart from some other types of alloys.
The parts manufacturing using this particular process are used in several different industries ranging from the food and beverage sector to decorative furniture to oil industry components to aerospace parts and much more. In many cases, metal spinning and hydroforming (using high pressure hydraulic fluid for shape metals in a die) are used in conjunction to achieve the desired forming process. Both of these processes call for engineering expertise, hence should only be carried out by an experienced and trained engineering firm.
People are familiar with the metal spinning process that is used for producing decorative items such as metal vases. However, this process has a higher relevance in the industrial sector where it is used for manufacturing high quality metal parts that are also very strong. It is to be noted here that the initial set-up cost of a metal spinning tool system is high. However, in the long run spun metal becomes very cost-effective. It can be used for producing a single part or thousands of parts as part of a production run. The higher the number of parts in a batch, the lower is the cost per part.
This process can be carried out on either a horizontal or vertical lathe. While in the early years metal spinning was carried out by hand, today it can be performed using hydraulic power or with CNC. If you look around, you shall notice that cookware is the most common product line that is a result of the metal spinning process. It is also used for manufacturing gas cylinders, and machinery parts.
When you approach a company that manufactures Spun Metal parts, it is important to ask them questions such as the maximum metal thickness that their machines can handle. You would also want to know the maximum and minimum size of parts that they can handle. Another important aspect that you would need to discuss is the typical delivery time.
The best part about metal spinning is that you need just a single piece of metal to manufacture different objects. This means that there are no seams that might threaten to crack or misalign over time. As far as alternative forming methods are concerned, metal spinning and hydroforming are considered to be the most ideal and cost-effective options available today.
