In the realm of metal identification, copper plates have always carried unique historical significance. From traditional casting to modern precision processing, the evolution of this craft reflects the transformation of industrial aesthetics.

During the manual engraving era, artisans hammered intricate patterns into copper blanks through wrist-driven force. Contemporary chemical etching now replicates micron-level precision patterns through photolithographic plate-making. This transition not only enhances efficiency but enables mass production of complex designs.

Surface passivation treatment determines copper plates' weather resistance. In sulfur-containing environments, untreated copper oxidizes black. Advanced passivation solutions create transparent protective layers through molecular-level sealing technology, preserving metallic luster while resisting outdoor corrosion for over two decades.

The architectural world is rediscovering copper's value. Curtain wall wayfinding systems using etched copper panels create textural contrasts between natural patina and glass facades. This time-dependent chromatic evolution grants building exteriors continuously evolving vitality.

In medal production, multi-layer lamination breaks new ground. CNC punching combines copper sheets of varying thicknesses to create three-dimensional relief effects. Light-shadow interplay across textured surfaces gives traditional awards dynamic visual depth.
