PLEASE NOTE: Swager capacities listed above are for normal reduction on low-tensile material. Capacity must be reviewed for each specific application.

Swaging machines, also known as swagers, are a low-cost way to efficiently point, reduce and form rod, tube or wire. Based on a simple principle, it is the process of shaping metal (forging) by means of a series of very rapid, blows delivered by rotating hammers and forming dies around a piece of work. It is a highly economical method to point tubing, rod, and wire for redraw, and to size, reduce, shape, taper, bond or form metal parts, hot or cold. Metal is formed – not machined – so there are no wasteful chips.

Swaging can be performed both hot or cold, although cold is popular because of its hardening effect on most materials. The process also improves grain structure, giving the part greater strength and an unusually fine finish.

A United States-based company, FENN offers swaging machine solutions for industries across the globe. From the manufacturing of state-of-the-art machines to installation, maintenance, and upgrades, we provide customers with unparalleled customer service from start to finish. Our team of engineers is highly trained to deliver metal forming solutions to address a variety of business initiatives that center around the formation of custom metal parts.

Types of Swagers: View the FENN Swager brochure here.

Rotary Swagers:
Used for the pointing, sizing and forming of wire, rod and tube. With a rotary swaging machine, the swaged section is always circular. Rotary swaging machines include 2-die and 4-die configurations.

  • Examples include: Cartridge heaters, hypodermic tubing, piping, armaments, and logging industry applications.

During rotary swaging, forming dies back by hammer blocks revolve around the workpiece. As the spindle revolves, centrifugal force throws the hammers and dies outwards against a series of rollers surrounding the spindle. Each time the hammer blocks strike diametrically opposed rolled, they are driven inward – causing the dies halves to close and compress the metal being swaged.

Stationary Die Swagers:
Complete parts can be made from entry rounds, squares, or rectangles – hot or cold. Types include simultaneous blow used to create fluted shapes & cross circular sections and alternate blow used to create rectangular shapes, squares, & hexagons. This method is capable of any cross-section other a perfect circle. During stationary die swaging, the spindle assembly remains stationary and the roller cage rotates.

  • Examples include: Aerospace tube components, and fluid control tubes.

Long Die Swagers:
This type of swaging machine is only needed with taper length exceeds the standard die length of a rotary swager. Long die swaging utilizes the same principle as the rotary method to produce long, shallow tapers for items such as furniture legs, sporting goods and aerospace products.

  • Serves a wide variety of materials: both welded & seamless tubing of either ferrous or nonferrous metals, from stainless steel to aluminum.

Used for the assembling of parts such as fittings to cable and for making reductions between shoulders such as on convoluted tubing. Hydroforming is a modification of the rotary swaging principle where wedges are used to open the dies while the spindle is rotating so the workpiece can be inserted before and removed after swaging.

  • Examples include: Sailing rigging equipment, architectural cable railings and recreational ropes course cables.


Basic Swaging Applications: View the FENN Swager brochure here.

A fitting is set over a cable, then inserted into the Swager and the cold forming force of the hammer actions produces a complete assembled piece. Examples include: Sailing rigging equipment, architectural cable railings and recreational ropes course cables.



End Forming:
A single piece of tube or rod is inserted into the Swager to a specified depth and reduced to a smaller diameter. The piece may be complete or ready for secondary operations such as drawing, drilling or tapping. Examples include: Aerospace tube components and fluid control tubes.



Through Swaging/Reducing:
Long lengths of cable, rod or tube are passed through the Swager. The entire length of the material is reduced to a smaller overall diameter, and the cold forging process produces a desired tensile strength or material property. Examples include: Cartridge heaters and logging industry applications.

FENN’s people made the difference.

Our business was looking to continue the progression of new and improved equipment to meet the changing needs of our customers. We chose to work with FENN on this project because of their willingness to collaborate on design features to meet our specific requirements for a machine of this size. This was a 15-month process from initial discussion to final program sign-off and machine installation. Communication was excellent throughout the building process. We were able to collaborate on any items, whether it was with FENN’s executives or directly with the machine builders. As with any custom first-off machine, there were minor issues that needed to be addressed. FENN corrected each of these and provided dedicated staff and resources to do so, which is one of the reasons we chose them for this project. The machine is actually exceeding our expectations. After having gone through a similar project 10 years ago, the FENN team improved all aspects of this project – from communication to delivery to the final product. From the initial outreach and conversation with the executive team, all the way through the delivery and minor issue corrections, it was done with people. FENN’s people made the difference. Since the beginning, a very important part of our decision making-process was wanting to work with a company that closely resembles the culture of our business and FENN met and exceeded our expectations.

FENN was very easy to work with

We decided to have our worn-out W-125SA Torin mechanical coiler retrofitted to a 2-axis servo coiler because our production required more feed length than a standard mechanical offered. We have other FENN-Torin coilers in our shop and are pleased with the support and customer service. The 2-axis retrofit has met our expectations as far as ease of set-up, since there was really no learning curve to the set-up and programming of the retrofit. We are now able to take spring production jobs we couldn’t run before on the mechanical W-125SA. FENN was very easy to work with during the retrofit process, keeping us updated on progress of the rebuild with pictures and a video of the finished machine. We recommend the Torin retrofit program as an economical way of rebuilding used FENN-Torin coilers, it was the right choice for us. We are also purchasing a rebuilt/retrofitted FENN-Torin FZ-115 6-axis coiler, to be delivered in February 2020.

FENN-Torin is our choice

In 2018 Mann-Hummel decided to replace an outdated cam driven spring coiler on a high-speed valve assembly machine. We use these valves in our oil filters for O.E. and Aftermarket customers. The equipment had become inefficient and spare parts were becoming difficult to find. The age and design of the equipment also made it difficult to train new personnel. We recognized it was time to modernize. We are not experts in making springs, so we had to increase our knowledge before making this important purchase. We researched on the internet and contacted several spring suppliers. After making several contacts we decided to observe several brands of spring coilers in a production environment. This also gave us the opportunity to ask questions about the equipment they had purchased. After talking with several spring technicians in the field we decided on a FENN-Torin Spring Coiler. Our Torin coiler has been in use for about a year now. Efficiency has increased and overall equipment repair cost is down. Although there have been learning curves with the new equipment FENN-Torin has supported us every step of the way. We are currently looking at a second coiler coupled with an assembly machine. FENN-Torin is our choice.

Top-Notch Machines

In 2009 we decided to purchase our first ‘Z’ CNC Coiler. The efficiencies gained by reduced setup time, increased throughput, and significantly reduced scrap rate while holding extremely tight tolerances was immediately realized through a complete statistical analysis. The machine paid for itself within months. Success with our first Torin ‘Z’ CNC led Springfield Spring to purchase another ‘Z’ CNC coiler, followed by three more of the latest model, the Torin FZ Series. Our five newest Torin spring coilers replaced all of our mechanicals, freeing up substantial space for new business endeavors. Fenn not only produces a top-notch machine but their sales, service, applications, and technical professionals are second to none. Fenn acts and responds like a business partner, not your traditional machine ‘dealer’.
