What is the smallest and largest part you can make?
The chart below outlines our cabalibilties with regards to common materials and our minimum-maximum capacity. Keep in mind that material thickness is an important factor as well.

In addition, some of the exotic metals we have worked with include: titanium, nickel, inconel, monel, silver, etc.

Are all spinnings round?
Due to the nature of the process, most spinnings are round. In some instances, spinning can be combined with other forming processes to produce slightly irregular shapes. Visit our photo gallery to get an idea of the variety of shapes that are possible.

What happens to the tooling once the job is completed?
As a customer of E.H. Schwab, you'll own the tooling once the job has been completed. It is customary, however, that we store the tooling at our plant. Not only does this increase turn-around time when a follow-up order is placed, but it also guarantees that your tooling will be available and in good condition for years to come.

What if a design change requires a change in diameter?
If the changes causes the inside diameter to decrease in size, the change will be relatively inexpensive. If the inside diameter increases, new tooling will have to be produced.

What tolerances can be maintained with metals spinning?

What are the benefits of metal spinning?
In general, metal spinning has significantly lower tooling costs than other metal forming processes. High volume production requiring tight tolerances can be handled via CNC equipment using steel tooling. Short run and prototype work can be designed and produced very economically using manual or semi-automatic equipment and wood or composite tooling. Click here for more info

Is metal spinning right for my needs?
The spinning process is generally limited to symmetrical shapes of circular cross-section such as: Cone, hemisphere, straight sided cylinder, etc. However, welding, stamping and/or machining techniques can be combined with spinning to achieve a variety of configurations. Give us a call, send an e-mail or fax and we'll review your drawing.

I've determined that spinning could work for my part. Are there any design tips I should keep in mind?
• Where possible, allow a center pilot hole to reduce cost.
• Use beads, grooves or flanges to add strength and rigidity.
• Large corner radii will add strength and is more cost effective.
• In some cases, tubing or rolled sheets can be used.
• Design changes reducing the inside diameter are relatively inexpensive, increasing the inside diameter requires new tooling.
