Leave everything from the production of all types of rolls to surface treatment to us!

Leave all aspects of manufacturing and surface treatment of various rolls used for shaping and secondary processing of films and sheets, such as extruders, coaters, printers, and stretchers, to us! We can sketch, CAD design, and manufacture rolls currently in use. We will also investigate and reproduce surface treatments. 【Features】 ◆ Capable of processing micron-level G polishing required for coater rolls and others ◆ Vertical polishing with a super mirror finish of 0.05S or less is also possible ◆ Surface treatments such as Tef-Lock treatment to prevent dirt adhesion and Cro-Amol treatment for high hardness are also available.

It is possible to consistently produce heat transfer circulation rolls, which are essential for film manufacturing and lamination processing lines, from iron core production to surface treatment.

A preheating and cooling roll is a roll that manages the surface temperature by circulating a heat medium such as water or oil inside the roll, serving the purpose of heating or cooling substrates like films and sheets. There are different internal structures, including single-tube type, double-tube type, and triple-tube type. The single-tube type has a hollow interior, and depending on whether the inlet and outlet are the same or different, it uses either a single or double rotary joint. While the single-tube type is cheaper to manufacture due to its simple structure, it has the drawback that as the roll size increases, it requires more heat medium for preheating and cooling, and the heat medium tends to stagnate, leading to uneven surface temperatures. The double-tube and triple-tube types have an internal tube placed inside the outer cylindrical pipe of the roll, allowing the heat medium to flow through the gaps between the pipes. This structure can limit the amount of heat medium to the flow paths, and since the heat medium flows through the gap between the outer and inner tubes, it can efficiently preheat and cool with less variation in surface temperature. If the inlet and outlet are different, it is structured as a double-tube type; if they are the same, it is structured as a triple-tube type.

This is an amorphous chrome plating that has improved heat resistance, which has been considered unsuitable for use at high temperatures.

It has an amorphous structure and possesses different characteristics from conventional crystalline coatings. Through heat treatment, its hardness can reach up to a maximum of Hv 1800, which is about twice that of hard chrome plating. While both chrome amorphous and hard chrome plating experience softening of hardness when used at high temperatures, chrome amorphous, which has reached its maximum hardness through heat treatment, can maintain a hardness of around Hv 1000 even when used at 600 degrees. Additionally, unlike chrome plating, which does not return to its original hardness after being used at high temperatures, chrome amorphous returns to its original hardness each time it cools to room temperature, making it suitable for use at high temperatures.

The durability and heat resistance of non-stick, high-release plating Tef-Lock have been significantly improved, making it possible to use it at 300℃!

- Our unique high-performance composite surface treatment combines the high hardness, wear resistance, and electrical conductivity of hard chrome plating with the non-stick properties, lubricity, low friction, and release properties of fluororesin. - Tef-Lock α maintains a stable surface without decomposition of the resin component even in high-temperature environments of 300°C, demonstrating excellent durability (conventional Tef-Lock has a heat resistance temperature of around 250°C). - In friction tests at high temperatures of 300°C, Tef-Lock α shows 2.4 times the durability of conventional Tef-Lock and approximately 7 times the durability compared to typical nickel plating combined with fluororesin.

[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.
