Even materials that are fragile and prone to tearing can now be processed thanks to the development of production equipment.
Electronic devices such as smartphones, PCs, and digital cameras generate heat during use, which can lead to performance degradation and low-temperature burns. As a countermeasure, materials with high thermal diffusion capabilities, such as graphite sheets, are used. However, while graphite sheets are thin, lightweight, and have greater thermal diffusion capabilities in the plane direction than copper, they are also very brittle and prone to tearing, making them difficult to handle. Our company has developed original processing equipment that enables mass production of thermal management products, specifically "thermal diffusion graphite sheets," through pressing, laminating, and pouch processing. - A special press processing technique that simultaneously punches out sheet-like graphite sheets while suctioning, transporting, and realigning them into a reel shape. - Production equipment capable of high-speed and high-precision continuous pouch processing and sealing of graphite sheets. - An online image inspection system for sorting defective products and an automatic sorting device. We leverage these technologies to address our customers' thermal issues. Additionally, we have introduced the same equipment in China and Malaysia, allowing for graphite sheet processing with the same quality as in Japan.

basic information
We own 3, 5, 8, 25, and 35-ton presses, with the 5-ton and 8-ton models primarily in operation. 5-ton press QDC specification: 180 Maximum processing dimensions: 180×150mm Speed: Up to 300 shots per minute (spm) 8-ton press QDC specification: 200 Maximum processing dimensions: 200×200mm Speed: Up to 170 shots per minute (spm) Both the 5-ton and 8-ton presses have a proven accuracy of 38 microns at the bottom dead center under certain conditions, with a processing accuracy of ±0.05 to 0.2 mm (0.1 mm PET). The equipment, including presses, is manufactured in-house, allowing for rapid customization. By combining presses, laminating machines, and image inspection machines, it is possible to manufacture products on a single line. Even if the above conditions do not match the processing requirements, customization may be possible, so please feel free to inquire.

Company information
Our company is an electronics parts manufacturer that specializes in die-cutting functional materials such as films, double-sided tapes, and cushioning materials. Among these, smartphone components have been adopted by all domestic manufacturers and some overseas, currently accounting for 70% of our total sales and becoming our flagship product. There are many die-cutting manufacturers around the world, but our significant strength lies in the fact that we design and develop most of our processing machines and molds in-house. This allows us to quickly introduce new products as needed, enabling us to respond swiftly to rapidly changing demands and smoothly accommodate specification changes for remodeling.
