We will be exhibiting at the Functional Film Expo 2022 held on July 27-28, 2022.

This is a surface treatment technology that dramatically improves the adhesion of fluororesin films and polyimide films, which have been considered difficult to bond until now.

At Kawamura Industries, we apply plasma treatment to films, metal foils, non-woven fabrics, and more, performing surface modification such as hydrophilization and hydrophobicity. This process significantly improves the adhesion of various films and allows for the removal and purification of organic substances from the substrate surface. It can effectively remove residues such as rolling oils that are difficult to completely eliminate with wet cleaning. Additionally, it is possible to bond various materials together without the use of adhesives. **Features of Kawamura Industries' 'Vacuum Plasma Treatment':** - Dramatically improves adhesion - Effectively removes rolling oils and organic substances, purifying the surface - Allows for adhesive-free bonding of various materials - Selects suitable gas types and plasma treatment conditions for each project - Treatment effects last for an extended period - Continuous processing is possible with roll-to-roll technology *For more details, please refer to the PDF document or feel free to contact us.*

Presentation of 4 technical introduction materials: We respond from prototyping to mass production! We also support material procurement. We can accommodate electronic materials that require high functionality, such as those for 5G products.

At Kawamura Industries, we create and provide electronic materials with various functions by integrating slit processing, plasma surface treatment, sputtering processing, thermal lamination, and more. We can handle everything from prototyping to mass production, including material procurement. We also welcome inquiries for small lot requests. 【Our Technologies】 ■ Slit Processing With about 50 years of extensive experience, we can accommodate slit widths from 2mm to 2,000mm. We can process not only in clean rooms but also in yellow rooms. ■ Plasma Surface Treatment Effective for improving the adhesion of low-adhesion films like fluorine films. Our roll-to-roll equipment allows for rapid mass production startup. ■ Thermal Lamination We have a vacuum thermal press capable of handling high temperatures up to 400°C within a clean room. Our laminating machines can also operate in a clean environment from the preparation stage. ■ Sputtering Deposition We possess roll-to-roll equipment. In collaboration with partner companies, we can also perform electrolytic copper plating on sputtered films using roll-to-roll methods. *You can view technical documents and introductory materials regarding the above processing technologies from the "PDF Download" section. Please feel free to contact us with any inquiries.

The "vacuum hot press," which can also perform surface treatment in the previous process, and the "coating" technology for metal foils are suitable for the processing of electronic materials such as substrates for 5G and base materials for planar heating elements!

Kawamura Industries develops and manufactures materials for electronic applications and provides associated processing technologies. We will introduce technologies that have been adopted for substrates for 5G and materials for planar heating elements. 【Our Technology: Electronic Materials - Strengths of Vacuum Hot Press Coating Technology】 ■ Vacuum Hot Press In prototype and mass production using vacuum hot pressing, we can press without adhesives, allowing us to better utilize the inherent properties of the materials. (Note: We can also accommodate laminated products with adhesives.) - We have a large number of pressing machines, capable of handling various sizes and temperatures. - There are pressing machines installed in a cleanroom environment. ■ Resin Coating on Metal Foil Although we operate in a contract processing format, we can combine "metal foil + high-temperature treatment." - Our coating drying oven can handle temperatures up to 260°C, allowing for the drying of high-boiling point solvents. - We can also accommodate polyimide coating with a high-temperature curing oven that can handle up to 400°C. Including material procurement, we provide consistent support from small lots and prototypes to mass production, so please feel free to contact us. * We are currently publishing an introduction document summarizing what Kawamura Industries can do! You can view it immediately from [PDF Download].

An article has been published about the case of introducing the expense reimbursement system "Rakuraku Seisan" at TSP Corporation. ~ In the case of TSP ~ Before the introduction, there were challenges such as dealing with the "paper" sent from various locations and the reliance on specific individuals for the tasks. After the introduction, the input and checking of FB data, which used to take 2 to 3 hours, can now be completed in just 5 minutes. Additionally, the mindset of the accounting department, which was previously reliant on manual entry, has changed. [Case Overview] ■ Challenges before introduction - Dealing with "paper" sent from various locations, reliance on specific individuals ■ Key points of introduction - A robust support system for setup and operation - Easy to start from a small scale both financially and functionally *For more details, please refer to the related links or feel free to contact us.
