Creating smooth, curved surfaces in metal sculptures requires a blend of traditional craftsmanship and modern techniques. One of the most effective methods is hammering and planishing, where artists use specialized hammers and stakes to shape the metal gradually, ensuring even curves. For larger pieces, hydraulic pressing or rolling machines can help achieve uniform bends without compromising structural integrity.

Another popular approach is welding and grinding, where sections are welded together and then meticulously ground down to create seamless transitions. For intricate details, chasing and repoussé techniques allow artists to refine curves by working the metal from both sides.

Finally, polishing and buffing are essential for achieving a mirror-like finish. Using progressively finer abrasives and polishing compounds, sculptors can eliminate imperfections and enhance the fluidity of the curves. Combining these methods ensures a flawless, professional result in metal artistry.
