YUKEN INDUSTRY CO., LTD. List of Products and Services

Due to the recent advancements in DX and IoT, the need for measures against electromagnetic noise generated by electrical and electronic devices has been increasing. We must keep an eye on various issues, including not only device malfunctions but also communication disruptions, health problems, and Tempest countermeasures. In response to requests for easy shielding solutions, wrapping around cables, and lighter sheets, we have developed EMC and noise countermeasure films and sheets. Leveraging our long-established surface treatment technology for resin components, we have created films and sheets with a special coating applied to ultra-thin resin films. They are lightweight, easy to handle, and can be easily applied or wrapped for use. 【Line UP】 YS-FC / YS-FP: Film type (YS-F series) YS-SC / YS-SP: Sheet type (YS-S series) 【Features】 ◆ Ultra-thin film/sheet with a minimum thickness of 40 microns ◆ Super lightweight at just 7.3 mg for a 1 cm x 1 cm piece ◆ This thinness allows for 99.99% (80 dB) electromagnetic noise shielding

In recent years, with the increase in electronic devices around us, the sources of electromagnetic noise have also increased proportionally. Since electromagnetic noise poses a risk of causing malfunctions in peripheral devices, the necessity for EMC measures such as "not emitting electromagnetic noise" and "not being affected by noise" has become more significant. In response, traditional measures using metal foils, seals, and sheet types have faced challenges regarding weight, workability, and electromagnetic wave shielding effectiveness. Yuken Industrial has leveraged its long-developed surface treatment technology for "plastic components" to address these challenges. 【Features】 - Significantly improved shielding effectiveness compared to metal foil and seal types - Capable of coating various shapes that cannot be addressed by metal foils, seals, or sheet materials - Lightweight due to switching from metal substrates - Blocks electromagnetic waves over a wide range of 80db or more *We are always accepting test processing requests.

The "Y Coat Type BL Plus" is a special coating technology that combines a unique dimple processing on the mold substrate with PVD coating to enhance release properties, allowing for excellent release effects over extended periods. The special dimple processing on the mold substrate reduces the contact area with the resin. Combined with the "Y Coat Type BL," which excels in corrosion resistance, wear resistance, stain resistance, and release properties, it reduces the release resistance value by 85% compared to untreated surfaces, and a reduction in release resistance has also been confirmed compared to Teflon-containing plating. (*Company test results) By reducing release failures and imparting various functionalities, it contributes to improving product quality and productivity. ★ We are currently offering a "Case Study Collection" that verifies the effects of "Y Coat Type BL Plus." *Please take a look from the "PDF Download" link below.
