Suppressing crack transfer and improving quality! "Super Mirror Crack-Free Roll"

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.

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.

Fukuda's new flagship model. - Masterless type (FLA-0200 series) - General type (FLA-0201 series) Two models of air leak testers. With the mastering correction function, high-precision measurements can be achieved in a short time. Please take a look at the catalog.

What is an Air Leak Tester? An "Air Leak Tester" is a device that pressurizes the inside (or outside) of a sealed workpiece with air and determines the presence of leaks based on pressure changes. When a master with no leaks and a workpiece with leaks are pressurized, the pressure on the workpiece side decreases, creating a pressure difference between the two. By measuring this pressure difference, the presence of leaks can be determined. Generally, differential pressure air leak testing is widely used, but Fukuda also offers products that utilize direct pressure leak testing and flow meters according to the leak rate, in addition to differential pressure leak testers. Since the air leak tester uses air as the measurement medium, it incurs no running costs and is environmentally friendly.

Fukuda Co., Ltd., which develops, manufactures, and sells leak testing equipment to inspect airtightness and sealing performance, provides a technical document that clearly explains the methods and theories of airtight testing, titled "Technical Manual." We are offering it as a PDF file. Please take this opportunity to download and view it!

● What is a flow meter? Flow meters measure flow rates using mass flow meters or laminar flow meters and perform pass/fail judgments based on flow rate criteria. They are ideal for measuring airflow and conducting performance tests. "FMZ-1063 series" This is a flow tester equipped with a mass flow meter. It offers high precision of ± 3.5 % of R.D. ± 1 digit (in the normal flow range). It features a time-saving function (scan measurement). The FMZ-1063 is a compact, all-in-one flow tester with various functions. "FU series" This is a flow measurement unit that integrates laminar and differential pressure sensors, making it smaller and lighter. When connected to a display indicator (model: MI-170), it can provide direct flow readings as well as pressure and flow judgments. "FLF-110 series" This is a laminar flow meter capable of measuring a wide range of flow rates from 2 NmL/min to 500 NL/min.
