The rotary swaging machine processes metal work piece for diameter reduction, end shrinkage, and material densification via cold or hot forming. The ideal work piece may be a rod, bar, pipe, wire copper rope, mild steel, stainless steel, titanium, alloy titanium, and other similar materials. After being processed by the rotary swaging machine, the work piece will have a smoother surface and a more solid form with significantly increased density. BOBO supplies this machine in either a manual model, or a fully automatic model with unmanned feeding, swaging, and unloading work. The rotary swaging mould will be three or four pieces, based on the provided client-side technical drawing.
