Spindustries Metal Spinning and Fabrication

FAQ's

What are the advantages to metal spinning?
With metal spinning, lead-times are usually shorter and tooling costs are significantly less than with other metal forming processes such as stamping. Lower volume production runs can be economically produced with metal spinning. Reverse angles and reveals can be possible with metal spinning. The many design possibilities and cost advantages make metal spinning an attractive process to consider for your next project.

What shapes can be spun?

Hemispheres	Venturis
Flanged covers	Cones
Dished heads	Funnels
Stepped parts	Parabolas

These are just a few of the shapes that are possible with metal spinning. In certain cases parts can have reveals or return angles. Please consult us for specific details.

What diameter blanks can you spin?

Aluminum	48" dia to .312 thick	60" dia to .190 thick
Mild Steel	48" dia to .250 thick	60" dia to .090 thick
Copper/Brass	48" dia to .250 thick	60" dia to .125 thick
Stainless	48" dia to .187 thick	60" dia to .075 thick

For certain special applications we can spin up to 84" diameter blanks.

What job quantities are candidates for spinning?
Short, medium and long running jobs are all candidates for spinning. Some jobs actually combine spinning and press work to obtain the desired part. Let us work with you when you are designing the part and we can help recommend the appropriate processes.

What are metal spinning tolerances?
Typically +/- 1/32". Each job must be evaluated on its own merits and special circumstances. Keep in mind that due to the nature of the process, tolerances normally are ID.

What are lead-times for jobs involving new tooling?
From 3 to 4 weeks is normal. Simple requirements can sometimes be produced more quickly and complex requirements can take longer.

What are lead-times for jobs with existing tooling?
Normal lead-times when existing tooling is on-hand at Spindustries is usually 2 to 3 weeks.
