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.

[To the owners of parking lots and parking lot construction companies] "I am worried about the possibility of colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those particularly facing sidewalks or roadways are expected to pose risks of dangerous incidents such as pedestrian collisions and vehicle-to-vehicle accidents. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures at various sites and alerts the surrounding area 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 that you 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] ○ 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.
