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.

The "Mechanical Stitch Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

Based on practical experience in support companies and business companies, SBS Marketing Co., Ltd. provides consulting services related to marketing, sales promotion, and customer acquisition primarily in the BtoB (business-to-business) sector. On September 23, 2025 (Tuesday), they published a page titled "Easier to Optimize the Allocation of Management Resources!? 'Product Portfolio Management (PPM)'". 'Product Portfolio Management' allows for the optimal allocation of management resources by evaluating one's business along two axes: "market growth potential" and "market share," and classifying it into four quadrants. The page explains the benefits that can be realized by utilizing it, the two axes and four quadrants that make it up, and the associated risks. (Page Overview: Excerpt) ■ What is 'Product Portfolio Management'? ■ What can be achieved through 'PPM'? ■ Components of 'PPM' (Vertical and Horizontal Axes) ■ Components of 'PPM' (Four Quadrants) ■ Two Risks Associated with 'PPM' (DL Content Only) ▼ For more details, please visit this page. https://sbsmarketing.co.jp/blog/ppm-2025-09/
