Cold Formed Metal Parts

DEFINITION OF Cold formed metal parts: Components that may be the product of flowforming, an advanced, cold forming process used to manufacture dimensionally precise, round, seamless, hollow parts.

Since the mid-1980s, Dynamic Flowform has used the precision flowforming process to produce hundreds of different thin-walled, cold formed metal parts to net or near-net shape. These cold formed metal parts are used in military, nuclear and industrial applications. Flowforming can be a cost-effective alternative to conventional manufacturing practices. By flowforming these cold formed metal parts, the parts often experience dimensional, mechanical or metallurgical benefits

Flowforming is a cold working process and is used to manufacture cold formed metal parts. Large amounts of refrigerated machine coolant are used during the process cycle to dissipate the adiabatic heat generated by the plastic deformation. The cooling of the workpiece, mandrel and rollers ensures that the material is worked well below its recrystallization temperature. Being a cold forming process, flowforming often achieves mechanical properties and dimensional accuracies that are far closer to requirements than any warm or hot forming manufacturing process.

Our flowformed metal parts range in size from diameters of 0.866” to 25.600” (22-650mm), wall thicknesses from 0.006” to 0.600” (0.15-15mm) with lengths up to 26.5 ft. (8 meters). Since flowforming poses no limitations on the relationship between cold formed metal parts, diameter and wall thickness, quite often we produce large diameters with precise thin walls.
