Forming''s Research & Development has led to production dies that can run hundreds of thousands metal of pieces while maintaining very close tolerances. Similar to pressing clay into a mold, cold forming is a process that forces metal wire into dies causing the metal to take the shape of the die. Cold forming employs high pressure at room temperature extrusion to force the metal to move beyond its elastic limit. It is predominately a closed die, forging operation used to form high quality parts and assure metal greater parts uniformity at a high rate of production. A cold forming machine can take 4-16 hours or more to setup, depending on the complexity of the product to be produced.

Types of Cold Forming Processes One-Blow Process one-blow extrusion cold forming is used for products with small head to shank ratios, such as standard fasteners or rivets. The two-blow cold forming process moves more material and allows upsets and extrusions to be achieved on the same component. The first blow provides the rough shape, while the second blow forms the final shape. process was developed to manufacture shapes which exceed the upset or extrusion limits of conventional one- and two-blow cold forming. Today, expanding cold metal forming technology is allowing increasingly complex components to be manufactured at very high production rates. Multiple-die Forming Through multiple-die forming, the final shape is achieved in stages. This six stage process, from cut-off extrusion to finished blank, often takes less than 1/2 second. Multiple-die machines have more forming stations to allow for: increased areas of reduction forming unique shapes such as multiple diameters on one component large head to shank ratios elimination of secondary operations such as drilling, turning and trimming, in many instances

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 metal often reduce part costs extrusion while improving part quality and productivity. Generally the wire is feed into the forming machine by means of metal feed rolls, cropped to length by a shearing action then progressively extrusion 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.
