Spiroforming and Spiropressing
Spiroforming and spiropressing are two methods of forming metal parts that are used in a variety of industries, primarily automotive and aerospace. These methods use a spiral tooling to cold-form parts that use a combination of rollers, dies and punches to create complex shapes with tight tolerances. The parts created using these methods are typically used as components in engines, transmissions and other assemblies, as well as for decorative accents on parts.
Spiroforming is a process that utilizes a rotary spinning and rolling tool to form parts. A spiroforming tool is composed of cup shaped pavers and punch heads, as well as a set of dies. The spinning and rolling of the tool creates the desired shape of the part, which is then cut to length by the punch heads. Parts created using this method can be highly intricate and accurate, as the rollers and dies allow for exacting tolerances to be maintained.
Spiropressing is a similar process, but instead of using rollers, dies and punches, it uses pressure to form parts. The tool used in this process is composed of two round plates that are separated by a honeycomb or circular slide abutment. Parts are placed between the two plates, then pressure is applied to form the desired shape. This method can be used to form parts of a variety of materials, including aluminum, stainless steel, carbon steel and other metals.
Both spiroforming and spiropressing produce parts with excellent accuracy and repeatability, and have become increasingly popular in the automotive and aerospace industries due to their ability to produce highly complex parts with tight tolerances. They are also increasingly being used for decorative parts such as air vents and greffes. In addition to these industries, both spiroforming and spiropressing are being used more and more in the furniture industry and for hobbies such as jewelry making.
Both of these methods offer a number of advantages to manufacturers, such as the ability to create intricate parts quickly, cost effectively, and with a high degree of accuracy and repeatability. Additionally, they can be used to form parts without the need to heat the component, which can help to reduce energy costs and increase efficiency. They also help to reduce tooling costs and labor costs, as only one set of tooling is needed to produce parts of a variety of shapes. Additionally, due to their relatively low cost and flexibility, they can be used in low volume production runs.
No matter what industry you are in, spiroforming and spiropressing can offer a number of advantages to your manufacturing processes. With the ability to produce complex shapes with a high degree of accuracy at a lower cost and in less time, these methods can help to increase efficiency and reduce costs for any business.
