Scheduled to exhibit at the Functional Film Expo 2022 (Osaka Industry Creation Center)

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.

Functional plating! We propose a special surface treatment technology for the maintenance of heat sealers.

"Teff Rock" is a special surface treatment technology that impregnates PTFE into micro-cracks of hard chrome plating. Are you having trouble with the maintenance of heat sealers? It complies with the standards for equipment and packaging based on the Ministry of Health, Labour and Welfare Notification No. 370, which includes food and additives. Therefore, it can be used in applications where food comes into direct contact. We offer free samples and can accommodate test applications. Please feel free to contact us. 【Features】 ■ Unlike Teflon coatings, it does not peel off in a short period of time. ■ It has a tremendous effect in preventing resin adhesion and stringing. ■ It prevents scratches on the sealing surface. ■ Heat resistance temperature is 250°C. ■ For resins with a high melting point, a heat-resistant version that can withstand over 300°C is also available. *For more details, please refer to the PDF document or feel free to contact us.

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.

Achieve maintenance of lubricity and improved load-bearing capacity and durability with micro-crack plating + PTFE!

We have a product called "Tef-Lock," which is our original plating that incorporates PTFE into hard chrome plating. This is a composite surface treatment that combines the high hardness and wear resistance of chrome plating with the low friction and lubrication properties of PTFE. However, in high-load environments where chrome plating may wear away, it has been difficult to maintain low friction and lubrication. However, we have developed "Tef-Lock Fine" by impregnating PTFE into our original Cro-Fine (high-hardness micro-crack chrome plating) coating, which solves these issues. 【Features】 ■ Hardness increased compared to conventional Tef-Lock (HV850 → HV900) ■ Increased crack density and higher PTFE content compared to conventional Tef-Lock ■ Maintains low friction under high loads and exhibits excellent wear resistance *For more details, please refer to the related links or feel free to contact us.

The hardness is approximately twice that of hard chrome plating (Hv1800)! Introducing the world's first amorphous chrome plating.

The world's first amorphous chrome "Cloamore" is a chromium-based alloy coating that contains 2-4% carbon, boasting ultra-high hardness and excellent wear resistance.

Are you having trouble with cracks in the plating transferring onto the mirror-finished rolls for film molding? It can be improved with crack-free plating.

Hard chrome plating has excellent hardness with a hardness value of HV750 to 900, but it has the issue of cracks (fine fissures) in the coating, which means that no matter how much the surface is polished to a mirror finish, the cracks can transfer to the product. Our company has long had the technology for a non-crack chrome plating called "Cloamore." The hardness can reach up to HV1800 through heat treatment at temperatures between 200°C and 600°C, and due to being crack-free, it has excellent corrosion resistance. However, since the coating can only be applied as a thin film with a thickness of up to 5μ, it has not been applicable to mirror surface rolls until now. However, we have developed a "Super Mirror Crack-Free Roll" that solves these problems by forming a special two-layer structure. 【Features and Effects】 ■ Achieves a super mirror crack-free surface with a roughness of Ry0.05 or less. ■ Since Cloamore is on the outermost layer, it has a hardness of about HV1200, which is approximately 1.5 times that of hard chrome plating, making it less prone to scratches due to its excellent wear resistance. ■ Being crack-free enhances corrosion resistance and reduces resin accumulation on the roll surface. It is also expected to improve anti-fouling properties and non-contamination effects. *For more details, please feel free to contact us.

We have successfully achieved high corrosion resistance that significantly exceeds 24 hours in the Cass test through the hybridization (composite) of plating films and inorganic materials!

Hybrid chrome is a technology that enhances the functional properties of chrome plating by hybridizing (compositing) chrome plating films with inorganic materials. Our company has successfully achieved corrosion resistance that significantly exceeds 24 hours in the Cass test through hybridization with glassy materials. By sealing the micro-cracks, which are a weakness of chrome plating, corrosion resistance has been greatly improved, and at the same time, it also prevents the intrusion of foreign substances into the cracks.
