New proposal for precision nanoimprinting! We have established a polishing technology that allows for processing without fogging or scratches.

The "High Precision Roll" can achieve nano-level surface roughness while precisely managing dimensional and shape accuracy, regardless of the material. We have developed our own roll grinding equipment and established a polishing technology that allows for processing without fogging or scratches. Additionally, the range of compatible materials has increased, and we can now process not only stainless steel, nickel, and glass, but also titanium and pure aluminum. 【Features】 ■ Achieves nano-level surface roughness ■ Established polishing technology that allows processing without fogging or scratches ■ Supports from single items to mass production ■ Handles everything from material procurement to complete processing *For more details, please refer to the PDF document or feel free to contact us.

[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.
