Aluminum surface treatment different from plating | Small lot of various types - Anodizing treatment
[Video comparing colors available] Instead of a coating like plating, the aluminum itself is reinforced. We provide surface treatment with excellent insulation properties for castings and large materials with short lead times.
If you want to enhance the functionality of aluminum products, please consider the surface treatment "anodizing," which takes a different approach than plating. Our company offers "hard anodizing," which can bring out characteristics superior to plating in terms of electrical insulation and heat resistance. With our deep understanding of aluminum properties, we can achieve high-quality finishes even for challenging materials such as castings and die-cast (DC) materials, as well as products that require complex masking. Additionally, we can flexibly accommodate detailed requests such as small lot production for prototype development, urgent short delivery times, and document preparation related to 4M changes. 【Our Features】 ■ Provides electrical insulation that is difficult to achieve with plating ■ Supports large materials and heavy items up to 1250mm in width ■ Compatible with castings, DC, and masking ■ Reliable ISO 9001 management system *For more details, please download our materials or contact us.
