Thin film aluminum evaporation

This portfolio piece demonstrates INAC’s thin-film aluminum evaporation technique applied to a model inspired by the inro, a traditional Japanese ornamental case. The result is a refined surface finish that combines a metallic mirror-like appearance with a unique semi-transparent effect.

A Finish That Changes with Light
One of the defining features of thin-film aluminum evaporation is the ability to control the thickness of the deposited coating. When the film is kept thin, light passing through reveals the internal shape of the model — creating a striking visual effect that shifts between an opaque metallic surface and a luminous, translucent form depending on the lighting conditions.

INAC’s Aluminum Evaporation Capabilities
Beyond standard aluminum vapor deposition, INAC offers a range of evaporation finishing options:

• Half-mirror vapor deposition (thin coating with a magic-mirror effect)
• Matte satin plating (low-gloss finish)
• Color plating combined with color clear coating

Painting and composite decorations can also be combined with evaporation for additional customization.

Bringing Craftsmanship and Technology Together
The inro’s layered, ornamental form provided an ideal subject to showcase the precision and expressiveness of INAC’s finishing techniques. This piece reflects the kind of results achievable when prototyping expertise meets advanced surface treatment — whether for exhibition models, design samples, or decorative mockups.
