Design / decoration

The industrial products around us are completed as products only when some kind of decorativeness is given to the visible parts.

Various methods such as painting and polishing are used to give the product decorativeness, but plating gives the product a metallic luster, texture, and luxury, and at the same time corrodes and wears the material. It can also provide functionality such as protection from.


Decorative plating as a modern industrial technology developed rapidly in the 1950s with the practical application of highly corrosion-resistant gloss plating technology for automobile bumpers.

It has been proven that rust does not occur even after 15 years of outdoor exposure by applying multi-layer plating to steel bumpers, which is a combination of 2-layer nickel plating / microporous chrome plating.

In the 1960s, steel and zinc die-cast materials were plated with multiple layers with chrome plating as the top layer, glossy copper plating / nickel plating / chrome plating, or nickel plating / chrome plating, and a so-called chrome gloss finish close to silver was applied. The interior and home appliances that have been plated have become a luxury item.

In addition, it was natural for automobiles to be chrome-plated not only on bumpers but also on all metal parts.

Today, the variety of glossy chrome-plated finishes are rather retro-inspired designs.

In the 1980s, the cool luster peculiar to chrome plating became tired as consumers' tastes changed and diversified. In automobiles, the adoption of glossy nickel plating / chrome plating has decreased sharply, including the adoption of urethane bumpers for the Toyota Celica released in 1977.

Similarly, in the field of jewelry, until the 1970s, glossy gold plating and silver rhodium plating were often used to create a sense of luxury.

Since 1980, diversification has progressed, and demand for antique finishes and silver-plated "astringent" tones has expanded.

The taste of design is changing with each era, but among them, the decoration by plating is used in familiar places while changing its shape.

[Plating process effective for design and decoration]
Nickel plating

Nickel plating has good corrosion resistance and excellent mechanical strength.

For this reason, nickel plating is widely used for decorative plating and functional plating (heat resistance, wear resistance, solderability).

Gold plate

It is a metal that has extremely high corrosion resistance and low contact resistance, and is also used in printed circuit boards, electronic components, and semiconductors.

Anodic oxidation "anodized"

Since aluminum oxide has a structure that forms fine pores (100 to 300 Å) when anodized aluminum film is formed, it is possible to color the pores by filling them with various substances. Is possible.

"Matte Black"

The black film "Matte Black" is a hybrid treatment of electroplating and coating.

It is a treatment suitable for processing on camera inspection equipment, etc. because it has a matte black film and can prevent reflection and craftsmanship.

Silver mirror film `` Clear Silva''

The base is silver, but by coloring it on it, it is possible to express various colors with metallic luster.

We have 9 existing colors available, but you can also adjust the toning and shade of the color, so you can express your desired image.
