Art and Design
Introduction and Scenario
A signature piece leaves the workshop in a single edition. There is no second batch on which to correct a process drift, no reference run on which to average a chromatic choice: the entire calibration concentrates in the prototype phase, and the piece that enters the plating cycle must come out exactly as planned.
An interior architect engaged Cromonichel for the metal plating of a sculptural furniture piece — a large-scale element, with an irregular geometry, part of a limited series destined for a signature collection.
The brief called for a specific finish, developed jointly with the studio, that would restore the chromatic reading intended in the original drawings.
Analysing the Challenge
Art pieces and signature elements bring three constraints into the plating cycle that series production rarely meets all at once.
The first is geometric: irregular shapes, variable sections, projecting parts, and deep recesses shift the current distribution inside the plating baths in a non-uniform way. The second is dimensional: large-format pieces require dedicated racks, compatible tanks and targeted management of current density across the full surface.
The third, and the most stringent, is the nature of the work itself: the object exists in a single edition, and a process error translates into damage that cannot be recovered on the material. The challenge was not to repeat a finish — as happens on a collection — but to land it on the first pass on the single intended piece.
The Cromonichel Process
The starting point was the dialogue with the design studio: drawings, sections, and reference visuals were analysed together to define the desired finish in technical terms before production began.
Test coupons were produced from portions of the same alloy and treated through successive cycles until they aligned with the requested chromatic reading.
Surface preparation on the final piece was calibrated to the specific zones of the geometry: concave areas, projecting parts, and section transitions, which required differentiated phases of degreasing and manual polishing to preserve the piece’s formal language.
The plating cycle was set up on a dedicated rack, built specifically for the piece’s geometry, with auxiliary shielding positioned to rebalance deposition in the electrically shadowed zones.
Current density, immersion times and bath composition were defined on the coupons and held constant for the full duration of the work. Manual operations — polishing in individual zones, finishing in transition areas — were carried out step by step, in continuous dialogue with the studio regarding the reading choices.
Quality control was carried out throughout the entire cycle, not just at closing: every step was verified before moving on to the next, because on a one-off piece, the final check arrives too late to be corrective.
Outcome and Value
The piece was delivered within the timelines agreed with the studio, with chromatic reading aligned to the original drawings and continuity of finish maintained across the full surface, including the zones of more complex geometry.
Cromonichel confirmed its ability to bring decorative plating beyond the perimeter of series production, into a language that dialogues with signature work — where value does not rest on repeatability but on the precision of a single pass.
Architecture studios, designers and operators in the art sector have identified Cromonichel as a technical partner able to accompany the project from the discussion on the drawings to the final outcome, integrating the plating finish into the language of the piece as part of the project, not as an applied layer.
