 Cold forming, or cold heading, uses forces greater than a metal''s elastic limit to form shapes without causing scrap material. Since raw material can be the most expensive aspect discbrakes of a part, cold forming is often a lower cost alternative to screw machining and other manufacturing methods. Benefits of Cold Forming Quality Improved strength and reliability discbrakes through work hardening and an uninterrupted grain flow Improved surface finish over screw discbrakes machined components Design Flexibility Unique and diverse shapes, including parts with multiple diameters, extrusions, blind holes and through holes Large head to shank ratios without secondary machining Eccentric or asymmetrical bodies possible Reduced Costs Reduced scrap rates High production rates Ability to form parts to a net or near-net shape, which requires fewer secondary operations to achieve finished form Allows multi-piece assemblies to be manufactured as a single component Cold forming often uses significantly less raw material for the same component. This reduction in compressive load yields reduces internal stress on the fastener during the joining process, so the fastener is less likely to fatigue when in the field. The mating parts are also subjected to less stress during the manufacturing process. The process also achieves a smooth finish and in some cases, eliminates cracks caused by traditional riveting. Also, since the effective forming load typically does not exceed the fastener''s column strength, cold-head forming is possible without bending or swelling the fastener shank. “Orbital can replace fasteners such as screws, snap rings, threaded discbrakes caps and rivets,” “For instance, studs cast in steel, aluminum, zinc, or even those molded into plastic, can be orbitally formed.” When should the Cold Forming process be considered? The part has multiple diameters High production quantities of the part are needed Significant raw material costs are associated with the part Part strength and reliability are important manufacturing criteria The Value of Cold Forming: Because raw materials are often times the most expensive component of manufacturing a part, Cold Forming is a low-cost alternative Cold Forming capabilities often reduce discbrakes part costs while improving part quality and productivity. Generally the wire is feed into the forming machine by means of feed rolls, cropped to length by a shearing action then progressively discbrakes cold formed. During the cold forming process, un-heated parts are forced into die cavities by forming punches to achieve a desired configuration, the friction between the forming tools and the material being formed results in an increase in temperature of the work-piece resulting in a work hardening effect.
