Metal Spinning Benefits and Applications

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.

Difficulties in Metal Spinning Special Alloys

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 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.

Need More Effective Lighting? Consider Metal Spun Light Reflectors

Light reflectors are used by architectural and commercial lighting professionals to augment artificial light. Since people obtain the majority of their information through their sense of sight, light reflectors are always in high demand; these products can provide appropriate lighting, which helps people process visual information faster and with greater clarity.

Metal Spinning Affords Fast Turnaround Times


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.

Metal Spinning Produces Tight Tolerance Components

Depending on the specific form and structure of a component, there can be more than one metal fabricating process that can be used to meet the same end. Although different processes can achieve similar results, there may be greater benefits of one over another.

Simplify the R&D Process with Metal Forming

 

In the metalworking industry, research and development (R&D) is vital for a successful manufacturing project.

After the initial product design, prototyping is the ideal next step in process; though producing a one-off part or component may seem like a simple task, this step is not without its issues. Prototyping can often consume time, leading to production delays, and tooling can cut into your company’s budget.

Metal Spun Spheres are Versatile and Cost-Effective

At Helander, we have provided clients with custom forming and fabrication services for the last 80 years. Our extensive experience has enabled us to specialize in several areas, but one of our core competencies is metal spinning.

Metal spinning is an ideal process for manufacturing high-quality round parts of different sizes and shapes—such as hemispheres and spheres. Our spherical metal parts are created simply and easily by joining two spun hemispheres; the resulting hollow spheres are imbued with the resiliency needed for the most demanding commercial and industrial applications.

Meet our Machines | 20 Hydroforming Press”

At the heart of Helander’s hydroforming services is our cutting edge 20″ hydroforming press. Sheet hydroforming is an ideal process for manufacturing parts with complex or asymmetrical geometries that would require multiple punch cycles in a matched die stamping process. By replacing one of the rigid dies with highly pressurized hydraulic fluid contained in a flexible diaphragm, its dynamics allow it to take on the form of any conceivable geometry. We use it to create an almost unlimited range of geometric shapes, either shallow or deep drawn, from a wide variety of metals and metal alloys.

Designed by engineering and manufacturing professionals with decades of experience in the machine tool industry, this hydroforming press sets the industry standard in hydroforming technology. Their pioneering pressure containment system offers a significantly reduced press size and operates with outstanding integrity and durability. Modern design software, state-of-the-art hydraulics, and computer-driven controls provide us with the capability to produce seamless parts that are extremely lightweight, strong, and durable.

This flexiblepress is fully programmable can be used interchangeably in the deep draw or fluid cell process mode. For deep drawn parts or those with curved geometries, the downward-acting bladder holds the material during pressurization as the tool is extended upward by a hydraulic punch cylinder. This draws the material into the bladder and allows it to flow as needed. By contrast, the fluid cell process allows the downward pressure of the bladder to form the material around the tool, allowing multiple parts to be run in a single cycle.

Operating at up to 10,000 psi, this hydroform features and advanced control and hydraulic systems that allows us to precisely manage the forming pressure of punch travel, which facilitates the production of net-shaped parts. Its “open” feature enables our operators to visually inspect parts mid-cycle, after which they can either continue the cycle or abort in order to modify the recipe – a significant time saver in new part development projects.

Maximum punch tool diameter is 15″, while draw depth capacity is 10″. Outfitted with components from well-known names in industrial automation, it gives us the capability to for an extensive PM program.
