We will give you a free copy of "Thin Film Q&A," which summarizes the differences and characteristics of various coating methods, coating examples, and frequently asked questions!

We are currently offering a free document that explains thin film processing technology, which imparts new functions to materials, in an easy-to-understand Q&A format! - What is vacuum deposition? - What is ion plating? - What kind of films can be created? - What types of coatings can be done? - Is it okay to only do prototypes? Can mass production be done? Toho Chemical Industry Co., Ltd. provides contract processing services for thin film coatings using ion plating (PVD), vacuum deposition, plasma CVD, sputtering, and other suitable surface treatment methods. Since the establishment of our ion plating division, we have accumulated approximately 40 years of achievements across a wide range of fields. We have compiled a list of frequently asked questions. We have summarized the differences and characteristics of each coating method, as well as specific examples of coatings, using illustrations and photos to make it as easy to understand as possible, so please feel free to download it. Based on our flexible response and over 35 years of experience, we will meet your needs! If you are considering functional thin films, please do not hesitate to contact us! If you have any questions, please feel free to reach out to us first!☆

Examples of thin film evaluation

The evaluation of thin films is determined by the purpose for which the thin film is used. For example, if the thin film is used for enhancing mechanical strength, important factors for evaluation include hardness and adhesion. If the film is intended to impart optical properties, values such as reflectance and transmittance become significant. Our company strives to meet customer needs using evaluation equipment as listed below.

In civil engineering sites, there are many instances where sheet boards are used for temporary roads, access roads, heavy machinery work yards, material storage areas, and pedestrian pathways. Traditional steel plates are heavy, which can require large cranes or heavy machinery for installation and removal, increasing the workload depending on site conditions. Hyper CLT sheet boards are civil engineering materials made from wooden CLT for civil use. The 5×10 board weighs about 230 kg, and the 5×20 board weighs about 460 kg, making them lightweight and easy to handle even with small machinery, which allows for easier installation without the need for large cranes. They also contribute to reducing the burden of transportation, installation, and removal, as well as improving maneuverability on site. Recommended as a registered technology by the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A," it is suitable for companies considering civil engineering, civil use, and civil CLT. This material is easy to use for creative proposals in public works, such as alternatives to steel plates, common temporary structures, temporary roads, and curing for material storage areas.
