Metal Spinning
Metal spinning is a metalworking technique with ancient origins, which still retains deeply artisanal elements today. Despite the technological advancement of machine tools, this process maintains unique characteristics that are often not replicable by automated equipment, or only partially so. The manual skills and experience of the operator remain essential components.
The process involves the progressive deformation of a metal disc until the desired shape is achieved. This is done using a tool that varies depending on the type of operation:
- In manual metal spinning, the tool resembles a rod with a steel or brass tip;
- In automatic or semi-automatic metal spinning, a roller made of metal or special plastic material is used.
The process is carried out in multiple steps, shaping the sheet metal over a forming die. During the operation, the stretching of the material may result in a significant reduction in thickness from the original.

Metals Used
To guarantee excellent results, we use only certified and carefully selected metals because quality starts with raw materials.
Al
Aluminum 99.5
Light, ductile, and highly malleable: it is the most versatile metal among those used in our processes. Easily paintable, it may present challenges in polishing, welding, and chroming processes.
Cu
Copper 99.5
Probably the oldest metal used by humans to make objects of all kinds: tools, jewelry, ornaments, and much more. Extremely versatile in finishes: it can be painted, welded, chromed, and oxidized to achieve highly valuable aesthetic and functional effects.
CuZn
Brass OT67
An alloy of copper and zinc, valued for its workability and aesthetic result. Often requires annealing treatments to prevent cracks and breaks during processing. It can be polished, welded, chromed, and oxidized, achieving surface finishes with great visual impact.
Steels
DC06 (formerly P06) with premium finish
Tough and versatile metal, used since ancient times for making tools and artifacts of all kinds. Modern alloys extend its potential, allowing processes once unthinkable. Suitable for numerous finishes: it can be welded, polished, oxidized, chromed, or painted.
Stainless Steels
AISI 304, AISI 316, and AISI 430
Chromium and carbon-based iron alloy, often enriched with other elements. The natural oxidation of chromium forms a protective layer that allows mirror finishes. Weldable, polishable, printable, and turnable – with some limitations – available in numerous qualities, including AISI 304, AISI 316, and AISI 430.
Perforated Sheet Metal
Stainless steel
The micro-perforated sheet is a metal plate (usually made of iron or stainless steel) characterized by a dense series of small holes regularly distributed across its surface. The holes are created through industrial processes such as punching or mechanical drilling.
