Metal Spinning Design Guidelines

              Metal Spinning Advantages

• Cold working improves tensile strength
• Forming process strengthens grain structure
• Cost advantages over casting or forging
• Uncomplicated tooling reduces lead times
• Lower cost, lighter weight parts

               Metal Spinning Shapes

• Symmetrical circular shapes-cones
• Minimum radii of about 1 to 1.5 times material thickness

               Materials

• Church Metal forms material from 24 gage up to 5/16" thick steel
• Common Steel: Cold rolled, hot rolled, A36
• High Strength Steel: Corten, Exten
• Stainless Steel: 304,316,321,409,430
• Nickel Based Alloys: Hastelloy, Inconel
• Copper and Brass
• Aluminum: O temper, H14, H32, 1100, 6061, 3003, 5052

               Tolerances

• The tighter the tolerances of a part the more time and care needs to be taken to achieve those tolerances.  The table shows guidelines for the cost concious, standard commercial parts and specialized parts.
