Metal Spinning Benefits and Applications

Posted by Samuel Ibrahim, Jr. on Tue, Oct 06, 2015

The metal spinning process consists of a tube or a disc of metal that is rotated at high-speed and machined into an axially symmetrical product using either a vertical or horizontal lathe. The advantage of spinning over other forming processes is its capacity to create seamless products from a single piece of material, with relatively low-cost tooling. Without seams, parts can withstand much higher internal and external pressures.

You will typically find spun metal components in decorative and architectural parts. Spun metal parts are also featured in variety of machines, cookware, gas cylinders, and brass instruments, and can be made from a variety of materials. Let's discuss the three most common materials for spinning. 

Steel

When considering material choices for spun parts, the most important factors are cost, the finished part's desired shape, and the application. It is well known that commodity prices fluctuate based on global supply and demand forces, fuel prices, and input material costs, but steel is generally a cheaper option than most other metals.

Steel is an extremely durable material, and much harder than aluminum. Its strength makes it less prone to warping, deformation, and bending under high forces or heat stress. Moreover, steel is a very dense material. In fact, it is 2.5-times denser than aluminum. This ensures that steel spun parts will not dent or scratch easily.


Aluminum

While aluminum is generally a more expensive option, it is more malleable and elastic than steel. It can therefore be used to create shapes with deeper and more intricate features – shapes that would end up cracking or ripping if spun with steel.

In addition to its malleability, aluminum is naturally resistant to corrosion and does not rust, and therefore it does not require any surface treatment after spinning. Since coating/painting is not required, you do not have to worry about scratching and surface wear, exposing the part to corrosion. This makes aluminum the natural choice for wet or abrasive environments. 


Copper

Copper, along with steel and aluminum, is one of the most commonly used materials in metal spinning. It is non-magnetic, versatile, and aesthetically appealing. Typically, copper is a more expensive option than aluminum or steel.

It is particularly known for its exceptional thermal and electrical conductivity, corrosion resistance, high ductility/workability, recyclability, and antimicrobial natural. Interestingly, its tensile strength actually doubles when work-hardened. Moreover, copper is a soft metal that is easy to work with.

Copper spun parts are often used for lighting, medical equipment, pipes and sinks, roofing, and decorative applications such as jewelry. 


Other Metals

In addition to steel, aluminum, and copper, Helander also manufactures spun parts using a variety of other metals such as Inconel, Hastelloy, titanium, bronze, and brass, each with their associated pros and cons. 

Metal spinning is often the best choice for symmetrical parts because of the seamless construction, low-cost tooling, and low levels of wasted material. A variety of metals can be formed into spun parts: the right choice depends on the cost requirements, the shape of the part, and the working conditions.

Steel is a low-cost material offering high strength and durability, while aluminum permits more complex part shapes and a greater resistance to corrosion. Copper is like aluminum in many ways, but is typically more expensive. For this reason, copper is often appropriate for applications where its aesthetic properties outweigh its high cost.

Difficulties in Metal Spinning Special Alloys

Posted by Samuel Ibrahim, Jr. on Mon, Aug 17, 2015

Too often in the metal fabrication industry, the phrase “we're not set up for that” really means “we don't want to do that.” When customers are met with either the unwillingness to manufacture their parts to print or the inexperience to know how to do so properly, the end project suffers greatly. Granted, it's important for designs to be practical and feasible, but when a manufacturer says, “metal spinning with special alloys is just too difficult” it's simply not true...for Helander Metal Spinning anyway.

Special alloys are in no way a hindrance to getting the custom parts you want, in the specifications you want them, and in the tightest of tolerances. In fact, one of the major advantages of creating parts via metal spinning is the ability to create quality, uniform, products out of traditional metal, alloys, and exotics alike. As long as a part is ductile it can be metal spun and even high-strength alloys are workable and machinable. 

 

The only difficulty in working with special alloys is narrowing down and making decisions about the endless possibilities of parts that can be manufactured.

What Kind of Alloys?

To reiterate, alloys are not only feasible to work with, they are actually highly malleable and form very efficiently. This includes high-strength materials as well as high-temperature and other special alloys, some of which include:

  • Hastelloy® – Considered an exotic metal, Hastelloy® is used when a project needs extra strength but also must be corrosion-resistant. Hastelloy® is a nickel alloy that can also include chromium, iron, copper, cobalt, and manganese. There are almost two dozen different types of Hastelloy® alloys and some of the properties can exceed that of stainless steel in corrosive environments. Despite being a high-performance, 'super' alloy, Hastelloy® forms well and responds to metal spinning, creating durable, rigid, resistant parts for use in a wide variety of industries.
  • Inconel® – A nickel alloy containing a large amount of chromium, Inconel® can be difficult to form in other metal fabrication techniques but responds very well to spinning. Inconel® is known as a high-strength steel that is not only extremely durable, but also resistant to corrosion and oxidization. It can be used in aerospace, chemical, and aqueous applications to name a few.

These are just two of the many special alloys that Helander Metal Spinning can fabricate using our metal spinning capabilities. To learn more about how we work with a variety of materials, or for specific information on your project needs, feel free to contact us today 630.268.9292.

When you Need Seamless Products, Turn to Metal Spinning

Posted by Samuel Ibrahim, Jr. on Mon, Apr 06, 2015

Modern industrial applications are far more demanding, and as such, companies must rely on different metal forming processes. There are several processes to choose from—including forging, extrusion, deep drawing, and others—but few can match the efficiency of metal spinning.

Metal spinning, known as spin forming, is an ideal forming process for creating cylindrical, round, or spherical objects that are both robust and axially symmetrical. During this process, a disc of metal is spun at very high speeds on a vertical or horizontal lathe; as the metal becomes more malleable, it is shaped to fit precise part geometries.

The uniform forces applied to the metal blank provide an equally uniform finished surface to the material. The finished part surface is exceptionally smooth and seamless, foregoing the need for grinding, welding, and other secondary finishing services. The seamlessness offered by metal spinning can be quite significant to industrial professionals.

Over time, seamless metal spun parts won’t succumb to cracking, breaking, or misalignment. This seamless construction gives products enhanced resistance to internal and external pressures—this is highly sought after in high-pressure applications.

Thanks to the enhancements provided by the metal spinning process, products such as tank heads and custom pressure vessels are more suitable to perform in harsh environments. Tank heads, fire extinguishers, scuba tanks, carbon dioxide (CO²) cartridges and other similar products must be capable of withstanding the most intense pressures. The seamless construction of metal formed products can also reduce cycle times, resulting in further cost efficiencies in the long run.

Metal Spinning Affords Fast Turnaround Times

Posted by Samuel Ibrahim, Jr. on Wed, Mar 25, 2015


When deciding on metal fabricating processes for component manufacturing, there are many factors to consider—turnaround time is one such factor that is of particular importance. Delayed project deadlines often result in costly consequences for many companies.

emisphereWhen choosing between different fabrication processes, turnaround can be just as important as the quality of the part. One of the main benefits of metal spinning is the short turnaround time on projects.

Tooling required for metal spinning is produced quickly and easily. The tooling dies of metal stamping or casting can take up to six weeks to manufacture, which can cause project delays. The expedited tooling of metal spinning enables parts to be completed and delivered in only four to six weeks. Tooling that takes less time to produce helps to accelerate the overall production cycle.

Metal spinning tooling can be made from a variety of materials. This flexibility in tooling improves production time and provides design engineers with greater performance features. For instance, geometric and dimensional changes from prototyping through production are easier and less costly than in other metal forming processes. Tolerances can also be adjusted if necessary.

Metal spinning also enables multiple operations to be performed in one set up, eliminating secondary set ups and refining production rates. When complex geometries are required, reducing manufacturing steps immediately improves the time required for each component.

Advancements in lathe technologies enable components to be produced with tight tolerances and extreme repeatability. Retooling of CNC machines is rare, but is a simple and fast process. If specialized tooling isn’t required, production can meet very short turnaround times (two to three weeks).

Since the ease of tooling provides shorter lead times, metal spinning is an ideal production method for axially symmetric parts and components.  This is a highly competitive option for metal forming, and the benefit of receiving completed orders promptly saves a considerable amount of time and added costs.
