Below is a list of Metal Spinning manufacturers from Minneapolis, Minnesota. Metal spinning, often called spin forming, is a cold metalworking process in which a flat metal disc affixed to a lathe mandrel is rotated at high speeds and formed by shaping tools. A metal spinner applies pressure to the rotating disc, which is called a blank, using several tools, which are called spoons, to shape the metal over a mandrel. This pressure can be applied by a single tool or by multiple tools. The finished product should have no wrinkling or warble, and the process is quick and cost-effective. An average metal piece will take only five to ten minutes to be formed, and very little metal waste is produced per part.
