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.
Our Beneficial Capabilities
With our state-of-the-art equipment, Helander has the capability to produce metal spheres using either CNC or hot spinning. These processes can produce parts with material thicknesses ranging from 0.018” to 0.0750”; typical tolerances are ± 0.015”, but tighter tolerances can be achieved depending on your specific needs. Additionally, metal spheres can be produced with diameters up to 60” and heights up to 30”.
Metal spinning is a highly economical means of manufacturing spheres. With metal spinning, lighter gauge materials can be utilized, cutting down on its already low tooling costs. This process requires sustainably less tooling than others such as stamping, casting, and forging; spinning eliminates the need to create expensive dies and patterns, which also makes it easier to set up.
Metal spinning produces less waste and can utilized preformed blanks, making it an environmentally friendly process. The smooth finishes yielded by metal spinning reduce the need for secondary processes, such as polishing, tumbling, deburring, and others—this helps you save even more on costs, while providing significantly shorter turnarounds.
Helander is capable of spinning several types of metals for production runs or varying sizes. Some of the typical spun metals include:
- Stainless Steel (300 and 400 series)
- Carbon Steel(s)
- Titanium
- Brass
- Aluminum (1100, 3003, 5052, 6061, 2024, and 7075 series)
- Bronze
- Copper
- Inconel®
- Hastelloy®
Applications of Metal Spheres
These versatile metal spun products can be utilized across several industries: petrochemical, oil & gas, water management, food & beverage, industrial heating, aerospace, automotive, power generation, agriculture, and many others.
Some commercial and industrial applications of metal spun spheres include:
- Boiler Feed Systems
- Steam Traps
- Sanitary Spray Balls
- Check & Air Valves
- Natural Gas & Oil Fields
- Oil Separators
- Water Distribution & Management
- And more
