It integrates with the base material and does not peel off. This is a surface treatment technology that achieves high hardness and insulation properties, unlike plating. It can also accommodate heavy objects weighing 400 kg and castings.
The general and hard anodizing we offer is a "surface treatment" that oxidizes and hardens the aluminum substrate itself, unlike "plating," which involves overlaying a different metal onto the surface of the metal. Therefore, there is no concern about the typical "peeling" associated with plating, and it forms a strong film that integrates with the substrate. In particular, hard anodizing exhibits excellent wear resistance, electrical insulation, and corrosion resistance due to its very hard and thick film. In terms of equipment, we are fully equipped with a large line capable of handling sizes up to 1250×650×2700mm (weight 400kg). You can also rely on us for large and long products that are difficult to handle with plating. 【Our Features】 ■ High-durability surface treatment with no film peeling ■ Support for a wide variety of small lots, including requests from a single piece ■ Large sheet materials such as 1250×2500 are also acceptable ■ ISO9001 certified, with support for audit documentation, etc. *For more details, please download the materials or contact us.

Strong against scratches and adaptable to harsh environments. Improving the wear resistance of automotive parts.
The essential difference between anodizing and plating is how the coating is formed! Anodizing involves "anodic oxidation treatment," which chemically alters the oxide film through electrochemical participation. The coating consists of a "part that grows inward toward the material" and a "part that grows outward," and it is integrated with the material. It is mainly used for aluminum products to enhance corrosion resistance and appearance. Plating involves electrochemical treatment with the metal as the cathode to generate a metallic coating. It is an image of a new metal layer building up on top of the base material. It is used for decorative purposes and to enhance corrosion resistance. In the automotive industry, there is a demand for long-term performance maintenance and improved reliability of parts. Our hard anodizing prevents peeling by integrating with the aluminum substrate, contributing to long-term performance maintenance.

Is it possible to anodize ADC12 with Silvec?
Q: Is it possible to anodize ADC12 (12 types of aluminum die-cast material)? A: Yes, it is possible. At Taisei BEC, we are currently processing anodizing for ADC12 every day. We also have a line specialized for ADC. * Regular anodizing Yashio/Japan ○ Available (Outsourcing: Can be handled by our partner company) Chonburi/Thailand ○ Available (In-house: Die-casting line and coloring line available) * Hard anodizing Yashio/Japan ○ Available (Outsourcing: Can be handled by our partner company) Chonburi/Thailand ○ Available (Outsourcing: Can be handled by our partner company)
When Silvec was anodized with ADC12, it changed to a brownish color. Is there a way to prevent this discoloration?
Q: When anodizing ADC12, it turned a brownish color. Is there a way to prevent discoloration? A: We sincerely apologize, but we are unable to accommodate that request. When anodizing ADC12, it naturally develops color. The presence of silicon (Si) can affect the coloration, and due to flow patterns during casting, it may also result in an uneven finish. Our company can implement processing methods to minimize this occurrence, but it is not completely preventable.
