METAL SPINNING

The METAL SPINNING is a simple process by which a defined round thin plate is pressed using a mandrel, also known as a form, is mounted in the drive section of a lathe. A pre-sized metal plate is clamped against the mandrel by a pressure pad, which is attached to the tailstock. The mandrel and work piece are then rotated together at high speeds. Due to the force applied, the work piece, the plate starts taking the shape around the mandrel, finally taking the shape of the bottle, can or lamp shade, for which the mandrel is designed for.

A more involved process, known as reducing or necking, allows a spun work piece to include re-entrant geometries. If surface finish and form are not critical, then the work piece is "spun on air"; no mandrel is used. If the finish or form is critical then an eccentrically mounted mandrel is used.

Features: Multiple operations can be performed in one set-up. Difficult shapes like cans, bottles with narrow neck, can be done using set forming parameters and part geometry by faster alterations in the initial set up. Cost is always lesser than conventional metal forming techniques. Tooling and production costs are also comparatively low. Spin forming is easily automated and an effective production method for prototypes as well as high production runs.Custom Parts made of metal spinning can be supplied by Custom Parts Online
