We have launched a specialized information site about black dyeing agents for black dyeing processing of steel.

Shortening delivery times, significantly reducing costs, and maintaining stable quality control. In both steel and casting, in-house black dyeing processing is possible.

The "Semi-Automatic Blackening Machine" is a set of blackening equipment and chemicals that allows for in-house processing of tools and steel parts with genuine blackening. ■□■ Do you have any of these concerns? ■□■ - Occurrence of red rust due to incomplete rinsing - Quality defects such as insufficient blackening film due to improper boiling By automating the concentration and temperature management of the blackening solution, which was traditionally done manually, the process of blackening can now be performed easily and without failure. 【Main Features】 - No color variation, consistent with the gloss of the material itself. A durable blackening film of magnetite (Fe3O4) can be created. - The film thickness is approximately 1μm, which does not affect dimensional accuracy. - The film is wear-resistant and will not peel off or discolor when rubbed. - The film retains anti-rust oil, providing excellent rust prevention (for indoor use). - The treatment solution can be reused repeatedly by topping it up without disposal, making it economical. - The wastewater used for rinsing can be discharged after neutralization with acid. - The entire process can be completed in about 15 to 20 minutes. For more details, please contact us or download the catalog.

Improving and stabilizing the quality of black dyeing! A revolutionary black dye that dyes both "steel" and "cast iron" black! It comprehensively improves issues such as color unevenness and early rust formation.

"Heating Black Dye Ultra Black Super" is a revolutionary heating black dye for steel and cast iron that finishes steel and cast iron, including reddish castings and special steels with poor color adhesion, in deep black. Various special steels can also be finished in deep black by slightly increasing the boiling temperature. It is a low-irritation odor type that suppresses the generation of irritating mist, significantly improving the working environment. Furthermore, we offer a "semi-automatic black dyeing machine" that allows for easy in-house black dyeing! *If you send us sample parts, we will return them after black dyeing! ■ Do you want to improve and stabilize black dyeing quality? Early red rust, color unevenness, bubbles, etc. Odec will propose solutions. Please feel free to consult us. 【Features】 ■ Black dyeing of steel, reddish cast iron, and special steels such as superalloys is possible under the same liquid and temperature conditions. ■ Reduces discoloration over time for cast iron and superalloys, maintaining the black coating for a longer period. ■ The treatment solution can be reused repeatedly by topping up. ■ Rinse water can be neutralized and discharged. ■ Generates less irritating mist, significantly reducing impact on the human body. *For more details, please refer to the PDF document or feel free to contact us.

Just soak the degreased workpiece at room temperature for 1 to 3 minutes! You can achieve blackening of steel.

"Instablack 333" is a room temperature black dye that requires no wiping. This product allows for black dyeing of steel by simply immersing degreased workpieces in it at room temperature for 1 to 3 minutes. Additionally, it does not leave smudges, making it possible to incorporate the black dyeing process into automated lines. The black dye layer is extremely thin (approximately 0.2μm) and does not affect dimensional accuracy. Improving and stabilizing black dye quality! ■ We want to improve and stabilize black dye quality ■ Early red rust, color unevenness, bubbles, etc. Audeck offers solutions to these issues.

Concentrated type that can be used for both immersion and application. Suitable for steel and cast iron up to HRC50. For blackening machine parts, repairs, and blackening of tools and jigs (used diluted 5 to 8 times).

The chemical reaction at room temperature finishes steel parts in the same black color as alkaline heat blackening. High Black has a fast reaction speed, allowing for not only immersion but also blackening finishes and repairs of assembled machine parts, as well as blackening large steel products that cannot fit into a tank through application or spraying.

Steel, aluminum, stainless steel, copper, brass, and more can be easily "blackened" with a spray.

The "Easy Black Dye Spray Black Seal" forms a genuine "matte" black coating of approximately 5 to 10μm just by spraying it on surfaces such as steel, aluminum, stainless steel, copper, and brass. It is resistant to corrosion and water, and is not affected by petroleum solvents or oils (it is not resistant to thinner-based solvents). Additionally, it provides rust prevention for about six months (indoors). Please make use of it for a wide range of applications such as black dyeing of small parts, repairs, prototype production, black dyeing after assembly, and pinhole repairs after black anodizing.

Full and empty management refers to the real-time display of parking availability and the management of efficient use of parking spaces. By utilizing Hotron's sensors, drivers can quickly discover available parking spaces, achieving efficient parking lot operations. ■ For large parking lots, the "floor management method" and "block management method," which focus on cost reduction, are recommended. Sensors are installed at regular intervals to count the number of vehicles passing through. This method offers the advantage of easy installation and low costs. 【Target Products】 - Vehicle Count Sensor CCS2 - Ultrasonic Sensor HM-UX2/UW2 ■ For smaller scale operations, the "space management method," which installs sensors in each parking space to display availability with high accuracy, is recommended. By ensuring accurate full and empty displays, it helps prevent unnecessary entry of new vehicles and enables safe parking lot operations. 【Target Products】 - Occupancy Detection Sensor HM-UX2/UW2 - Occupancy/Pass Detection Sensor HM-LC6 - Occupancy Detection Sensor HM-LC7/LC7-FLS - Occupancy/Pass Detection Sensor HM-S6 - Occupancy Detection Sensor HM-S8
