Typical Applications
• Electronic components. • Electrical contacts. • Nails. • Bolts and screws. • Pins. • Small shafts.
Design Aspects
• Complexity limited to simple cylindrical forms with high degree of symmetry. • Significant asymmetry difficult. • Minimisation of shank diameter and upset volume important. • Radii should be as generous as possible. • Threads on fasteners should be rolled wherever possible. • Head volumes are limited due to amount of deformation possible. • Inserts are possible at added cost. • Undercuts are produced via secondary operations. • Machining usually not required. • Draft angles not required. • Minimum diameter = 0.8 mm. • Maximum diameter = 50 mm. • Minimum length = 1.5 mm. • Maximum length = 250 mm.
