The aluminum-resin bonding system is often used for applications such as weight reduction, improvement of joint strength and reliability, increased productivity, and cost reduction. As surface treatment, various chemical treatments and anodizing (alumite treatment) have been commonly performed. In recent years, there has been a growing demand for these surface treatment technologies to improve the reliability of composite materials, diversify materials combined with aluminum, and reduce the environmental impact of the adhesive process. Therefore, we applied the anodizing treatment "TAF AD" for adhesive bonding to the surface of the parts. As a result, not only was the adhesive bonding strength improved, but bonding can also be achieved without the use of adhesives (primers) even in cases where adhesives were previously used. [Challenges and Background] ■ Adhesive bonding is increasing due to demands for weight reduction, energy saving, automation, shortening of processes, and rapid bonding. ■ There is a growing demand for improving the reliability of composite materials, diversifying materials combined with aluminum, and reducing the environmental impact of the adhesive process. *For more details, please refer to the PDF document or feel free to contact us.

Ultraviolet rays, which exhibit various effects, can sometimes degrade the devices and components themselves. Aluminum parts that have undergone black anodizing will decompose the black dye molecules within the coating when continuously exposed to ultraviolet rays, leading to discoloration and fading. Therefore, we apply a special black anodizing treatment, "TAF TR BK" or "TAF TR SBK," to the surface of the parts. This prevents discoloration over time and reduces the reflectivity in the visible light range, making it useful for preventing stray light in light source devices and other applications. [Issues and Background] - Ultraviolet rays, which exhibit various effects, can sometimes degrade the devices and components themselves. - Aluminum parts that have undergone black anodizing will decompose the black dye molecules within the coating when continuously exposed to ultraviolet rays, leading to discoloration and fading. *For more details, please refer to the PDF document or feel free to contact us.

After using experimental equipment and medical devices, they may undergo sterilization treatment at temperatures above 180°C. When using aluminum for such components, heat resistance is required, so hard chrome plating is often employed. However, plating treatment has unstable adhesion to the material, contains a large amount of chromium, and is also costly, necessitating the consideration of alternative surface treatments. Therefore, a heat-resistant crack-free hard anodizing treatment called "TAF TR," which can be used without cracking even at high temperatures, is applied to the surface of the components. As a result, stabilization of quality and chromium-free production can be achieved, while also reducing costs. [Challenges and Background] ■ Plating treatment has unstable adhesion to the material, contains a large amount of chromium, and is costly, making it necessary to consider alternative surface treatments. *For more details, please refer to the PDF document or feel free to contact us.

Lighting equipment and scientific products can cause parts to become high-temperature during use, leading to issues where the black anodized coating on the exterior changes color or fades. To address this, we apply a black anodizing treatment "TAF TR BK" that does not discolor even at 350°C to the surface of the parts. After application, the color does not fade even at 350°C, enhancing not only the design performance but also providing a harder coating than standard black anodizing, which improves scratch resistance. [Challenges and Background] ■ Lighting equipment and scientific products can cause parts to become high-temperature during use, resulting in issues where the black anodized coating on the exterior changes color or fades. ■ Changes in the color tone of the parts can diminish the inherent luxury and cohesive design value of the product. *For more details, please refer to the PDF document or feel free to contact us.

Optical components for product inspection use a matte black anodized treatment to prevent unintended light reflections. However, conventional black anodizing uses organic dyes for coloring, which can decompose and fade at temperatures above 100°C. Therefore, we apply a heat-resistant matte black anodized treatment called "TAF TR SBK" to the surface of the components, which maintains its color even when heated to 350°C. Since it does not fade at high temperatures, it is possible to increase the operating temperature range of precision optical components. [Challenges and Background] - Recently, performance standards have become stricter, increasing the need to test product operation at high temperatures. - Conventional black anodizing uses organic dyes for coloring, which decompose and fade at temperatures above 100°C. - Fading of components reduces anti-reflection performance and compromises the accuracy of inspection devices. *For more details, please refer to the PDF document or feel free to contact us.*

In the manufacturing process, attempts are being made to change materials to aluminum from the perspective of energy conservation and reducing the burden on workers through lightweighting. For jigs used in heat treatment of products at 300°C, high-heat-resistant coatings may be applied through methods such as vapor deposition, thermal spraying, or special coatings, but there has been a challenge to reduce costs. Therefore, heat-resistant hard anodizing treatments "TAF TR" and "TAF TR BK" are applied to the surface of the parts. After application, not only is heat resistance secured, but there are fewer restrictions on the shape during surface treatment, and compared to heat-resistant paints, dimensional accuracy is also superior, thereby improving the precision of the jigs. [Challenges and Background] - In the manufacturing process, attempts are being made to change materials to aluminum from the perspective of energy conservation and reducing the burden on workers through lightweighting. - When using aluminum, surface treatment is almost always required. - For jigs used in heat treatment of products at 300°C, high-heat-resistant coatings may be applied through methods such as vapor deposition, thermal spraying, or special coatings, and there is a desire to reduce costs. *For more details, please refer to the PDF document or feel free to contact us.*

Some pickles and seasonings have a high acidity that can corrode aluminum when exposed for long periods. Aluminum parts used in conveying equipment may undergo hard anodizing treatment; however, the hard anodized film contains countless cracks, and even if they do not come into direct contact with the product, corrosion can progress due to splashes and other factors. Therefore, we apply crack-free hard anodizing treatment "TAF TR" to the surface of the parts. After application, it can suppress corrosion and extend the lifespan of the parts. Additionally, it reduces the risk of line troubles caused by the contamination of foreign substances due to corrosion.

The care robot suit relies on lightweight design, simplicity, and safety. Regarding the bonding of the polyester fabric and aluminum substrate in the sleeve that goes over both arms, we decided to use adhesive bonding. However, not only is stable adhesive strength difficult to achieve, but there is also the issue of corrosion and deterioration due to sweating inside the sleeve during use, leading to peeling. Therefore, as a pre-treatment for bonding the aluminum substrate and polyester fabric, we applied a base anodizing treatment called "TAF TR" to the surface of the parts. This allows for stable and good adhesive strength, ensuring consistent quality, and reducing the frequency of parts replacement and maintenance, thereby decreasing the burden on users. [Challenges and Background] - Regarding the bonding of the polyester fabric and aluminum substrate in the sleeve that goes over both arms, using bolt fastening takes up three-dimensional space at the bolt points, narrowing the range of motion for the arms. - We decided to use adhesive bonding, but not only is stable adhesive strength difficult to achieve, there is also the problem of corrosion and deterioration due to sweating inside the sleeve during use, leading to peeling. *For more details, please refer to the PDF document or feel free to contact us.*

The resin layer of the printed circuit board plays an important role, including its thickness, in ensuring the necessary insulation for electrical design. However, the thicker the resin layer, the more time it takes for lamination, and particularly in power devices, the decrease in thermal conductivity raises concerns about reduced cooling efficiency. Therefore, we use a combination of crack-free hard anodizing treatment "TAF TR" and base anodizing "TAF AD." By replacing the resin with an anodized coating, we can reduce film formation costs and enhance cooling effects with the high emissivity of the anodized coating. [Challenges and Background] ■ The thicker the resin layer, the more time is required for lamination. ■ Particularly in power devices, the decrease in thermal conductivity raises concerns about reduced cooling efficiency. ■ When using anodized coatings as insulation layers, issues such as bubbling and peeling due to heat during the manufacturing process are unavoidable. *For more details, please refer to the PDF document or feel free to contact us.

Resin sealing materials are used at the battery terminal and the opening of the drainage treatment device to prevent the leakage of internal chemicals. Such resins have poor adhesion to aluminum, and even when bonded, there are many cases where the adhesive deteriorates and peels off during use. Therefore, an anodizing treatment for the base, "TAF AD," is applied to the surface of the parts. This not only improves adhesive strength but also eliminates the need for adhesives, making quality control easier and reducing the risk of excess adhesive adhering to the product. [Challenges and Background] ■ Resin sealing materials (packing rubber and sealing materials) are used at the battery terminal and the opening of the drainage treatment device to prevent the leakage of internal chemicals. ■ Resins have poor adhesion to aluminum, and even when bonded, there are many cases where the adhesive deteriorates and peels off during use. *For more details, please refer to the PDF document or feel free to contact us.

The hydraulic control device, when there are cracks in the hard anodized coating on the surface of the parts, will have the cracks spread, causing oil to seep out along the cracks, making it impossible to control the hydraulic pressure. By applying the heat-resistant crack-free hard anodizing treatment "TAF TR" to the surface of the parts, it is possible to prevent oil seepage and coating peeling from the cracked areas. Not only can seepage and peeling be eliminated, but the surface roughness can also be improved compared to conventional hard anodizing. [Issues and Background] - If there are cracks in the hard anodized coating on the surface of the parts, repeated use at high temperatures will cause the cracks to spread, leading to oil seeping out along the cracks and making it impossible to control the hydraulic pressure. - Problems with the anodized coating peeling off from the cracks are also likely to occur. *For more details, please refer to the PDF document or feel free to contact us.

Currently, in the design of components, there is an increasing number of situations where aluminum and resin slide against each other. On the aluminum side, hard anodizing is often chosen as the surface treatment. However, the compatibility with the counterpart material, the geometric characteristics, and especially the cracks on the hard anodized surface can cause excessive wear on the resin during sliding. Therefore, by applying crack-free hard anodizing treatment "TAF TR" to the component surface, we can prevent wear of the resin material that is sliding against it. The reduction in resin wear allows for designs using material combinations that were previously not feasible. [Challenges and Background] - Currently, there are increasing situations where aluminum and resin slide against each other in component design. - Hard anodizing is often chosen as the surface treatment for aluminum. - The compatibility with the counterpart material, geometric characteristics, and especially cracks on the hard anodized surface can lead to excessive wear on the resin during sliding. *For more details, please refer to the PDF document or feel free to contact us.

Standard black anodizing can decompose and fade when exposed to heat or prolonged ultraviolet or sunlight, causing the dye in the microscopic pores of the coating to break down. Additionally, not only does this affect the color tone, but stress caused by differences in the coefficient of linear thermal expansion between the base material and the coating can lead to cracks and coating loss, resulting in a loss of surface protection functionality. Our 'TAF TR BK' is a heat-resistant and UV-resistant black anodized treatment that does not crack, discolor, or peel even under high temperatures of 350°C or in environments exposed to ultraviolet light. 【Features】 ■ No discoloration, peeling, or degradation even when heated, with excellent long-term durability ■ Black anodizing that does not fade even at high temperatures of 350°C ■ No discoloration or change when exposed to ultraviolet light ■ Excellent dimensional accuracy ■ Superior adhesion to the material ★ Evaluation samples are available upon request.
