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

Shortened delivery times, significant cost reductions, and stable quality management. 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 issues such as insufficient blackening film due to improper boiling By automating the management of the concentration and temperature of the blackening solution with a computer, blackening processing can be performed easily and without failure, which previously required constant supervision. 【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 about 1μm, which does not affect dimensional accuracy. - The film is wear-resistant and does not peel off or discolor when rubbed. - The film retains rust preventive oil, providing excellent rust prevention (for indoor use). - The treatment solution can be reused repeatedly 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.

This product allows for black dyeing of steel by simply immersing degreased workpieces at room temperature for 1 to 3 minutes. Additionally, it does not leave any smudges, making it possible to incorporate the black dyeing process into an automated line. The black dye layer is extremely thin (approximately 0.2μm) and does not affect dimensional accuracy. Improving and stabilizing black dyeing quality! ■ We want to improve and stabilize black dyeing quality ■ Early red rust, color unevenness, bubbles, etc. Audeck offers solutions to these problems.

Concentrated type usable for both immersion and coating. 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 components in the same black color as alkaline heating 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 about 5 to 10 μm 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.

[To the owners of parking lots and parking lot construction companies] "I'm worried about the possibility of colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those facing sidewalks or roadways are particularly prone to dangerous incidents such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures at various sites and alerts the surroundings with LED lights and buzzers. The system consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *When using the exit warning system, we kindly ask customers to arrange for the switching power supply (24V), LED rotating light, control panel, circuit breaker, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. [Contents Included] ○ Vehicle Exit Warning System Configuration ○ Comparison Table of Exit Warning Sensors ○ Four Modes ○ Wide Range of Applications ○ Customer Feedback ○ Appearance Diagram / Specifications ◎ For more details, please contact us or download the catalog.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If you require a detailed technical explanation, please contact us.
