>> Metal Spinning
Because of low tooling costs, manual metal spinning is used
extensively for production runs of 1,000 pieces or less. We
utilize deep drawn preforms in our metal spinning process.
Metal spinning is an excellent means for quickly prototyping
round hollow metal forms. Metal spinning is carried out by
the application of an even, levered force applied to metal
uniformly by rotating the metal and its intended form (mandrel)
at very high rpm's. metal is deformed evenly in the
metal spinning process without any wrinkling or warbling.

>> Quality Control You Can Depend On
Williamsburg Metal prides itself on its quality.
That's why we make sure that from material
sourcing and selection to shipping, every
operational step along the way in a metal
stamping and metal spinning project is
inspected and passed or approved to ensure
the highest quality product created at the most
efficient level of manufacturing and service.
As the Quality Control process is managed,
each and every operation and/or change is
properly documented and saved for future
reference. Repeat metal stamping and
metal spinning jobs are handled much
easier because of this and a level of metal
stamping and metal spinning consistency
in repeat jobs is achieved that surpasses
our customers' expectations.
