Just applying pressure (surface pressure), and here is an amazing heat management solution! It has high durability and does not suffer from characteristic degradation due to pump-out or dry-out phenomena. It can be used for a long time while maintaining stable low thermal resistance, making it a reliable heat dissipation material. With the increase in heat generation due to improved semiconductor performance and the miniaturization of devices, the efficiency of thermal management has become a significant challenge. Zebro can be utilized for efficiently dissipating and cooling the heat generated by power semiconductors supplying high current and high voltage, as well as electronic components such as high-brightness and high-output LEDs/LDs. For those looking for TIM with good thermal conductivity or facing issues with insufficient cooling from conventional heat dissipation materials, we provide thermal management solutions tailored to your needs.

The "Lotus Core" can reduce the curling of films and labels! It is mainly used for winding separator films and in the winding processes of tack labels and tack seals. It is also effective for winding semi-finished products before they are cut into sheets. With existing equipment, it is possible to increase the winding diameter (6 inches/8 inches). It addresses cost issues related to equipment modifications and dummy winding of products. The more expensive the film, the greater the expected improvement! It prevents the deterioration of film performance caused by "curling" and "strong winding pressure" that occur during the winding process.

• Paper and pulp products

We will introduce examples of packaging materials that solve problems related to the packaging and transportation of large films weighing over 1 ton. For film rolls such as polarizers, which weigh around 1 ton each, a combination of metal roll pallets and FRP cores is fundamental. Many products are headed to China and South Korea. The design is built to withstand the G-forces experienced at sea and when traveling on poorly maintained roads. In terms of cost, it is reasonable and not as expensive as aluminum. The roundness of the FRP core is less than 0.05. The pallets can be folded and reused.

• fiber

It prevents twisting and collapse during transport by sandwiching with a perforated honeycomb board. The paper packaging material is lighter than wooden boxes and wooden pallets, making assembly and loading of products easier. The used packaging material can be disposed of as paper waste.

At Showa Marutatsu Co., Ltd., we propose a solution for "wrinkle elimination" using M cores and G cores that have no spiral grooves. In standard paper tubes, the spiral grooves can transfer to films and sheets, causing wrinkles. Since M cores and G cores do not have spiral grooves, such wrinkles do not occur. During the winding of films, various issues can arise due to factors such as the winding core, equipment, and working environment, leading to winding troubles with the film. Kiku wrinkles are one such issue. We propose solutions for Kiku wrinkles from the perspective of the winding core. 【Features】 ■ M cores and G cores do not have spiral grooves, so wrinkles do not occur ■ Eliminates winding wrinkles, wrinkle transfer, and winding habits ■ Proposes solutions for Kiku wrinkles from the perspective of the winding core *For more details, please refer to the PDF materials or feel free to contact us.
