Manufacture of metal products

[Strength of products/technologies]
Our company conducts hard anodic oxidation coating (improved wear resistance) and stained anodic oxidation coating (colored red, blue, gold, brown, black, green, etc.). We also conduct superimposed electrolytic treatment (including coating of difficult-to-coat materials such as those numbered 2000 or 7000 and high-speed anodic oxidation coating) and oxalic-acid anodic oxidation coating (higher hardness and good corrosion resistance, even under the same conditions as the sulfuric acid method). We handle various kinds of aluminum materials, such as wrought or die-cast, numbered 1000, 2000, 5000, 6000, 7000, and so on. Anodic oxidation coating thickness may be 0.5μ to 80μ, and hardness up to 450HV, depending on the material.

[Representative's message]
Since establishment, we have specialized in aluminum-based anodic oxidation coating and have manufactured products which are appreciated and trusted by customers. To keep up with the changing times and environmental trends, we keep improving products under the motto “Better products more safely at lower prices” to meet customer needs.
