We will be exhibiting at the Adhesive and Bonding Technology Exhibition 2023 held on June 16, 2023.

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 modifications such as hydrophilization and hydrophobization. This treatment 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 adhesive strength - Effectively removes rolling oils and organic substances, purifying the surface - Enables 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 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 processes such as slitting, plasma surface treatment, sputtering, and thermal lamination. We can handle everything from prototyping to mass production, including material procurement. We welcome inquiries for small lot requests as well. 【Our Technologies】 ■ Slitting With about 50 years of extensive experience, we can accommodate slit widths from 2mm to 2,000mm. We can process in clean rooms as well as 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 We possess roll-to-roll equipment. In collaboration with partner companies, we can also perform electrolytic copper plating on sputtered materials using roll-to-roll methods. *You can view technical documents and introductory materials regarding the above processing technologies from the <PDF Download>. Please feel free to contact us with any inquiries.

The "Mechanical Stitching 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.

We are currently running the VariCAD Start Support Campaign, where you can purchase VariCAD at a special price! During the campaign period, new licenses are available at 20% off the regular price. Additionally, during the SALE period, we are distributing discount coupons (note: there is a validity period for use) that can be used after the SALE ends. Customers who wish to experience VariCAD before making a purchase can obtain this coupon during the SALE period and use it later after their trial. The initial setup cost is priced at around 100,000 yen (including one year of maintenance support and upgrades) due to this discount campaign, and the annual maintenance support running cost from the second year onwards is around 50,000 yen (with conditions for purchase in the renewal month), making the total cost lower compared to other products. Why not take advantage of this campaign and start using 3D CAD at a great price? ◆ VariCAD Start Support Campaign Special Site https://varicad.add-soft.jp/support/?page_id=17614

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.
