We will be exhibiting at the Thermal Tech 2026 event held on April 24, 2026.

It is a heat-resistant laminated board that integrates polyimide film without adhesive.

Kawamura Industries' "Polyimide Laminate (PI-Plate)" is a laminate made by layering and thermally bonding polyimide film that has been activated on its surface through plasma treatment. **Features of Kawamura Industries' "Polyimide Laminate"** - Excellent heat resistance due to being adhesive-free → Continuous: 200°C / Short-term: 400°C - Exhibits excellent mechanical properties derived from polyimide film - Laminates can be produced in sizes up to 480mm x 1,100mm - Maximum thickness of 10mm (proven) *Please feel free to consult us regarding thicknesses over 10mm. *For examples of properties, please refer to the PDF document or feel free to contact us.

"5% weight reduction temperature is 534℃!" This is a stainless steel/polyimide substrate suitable for high-temperature planar heating heater applications, without the use of adhesives.

Kawamura Industries provides stainless steel/polyimide materials by leveraging the know-how of polyimide coating technology developed over many years on stainless steel foil. **Features of Kawamura Industries' "SUS/Polyimide Material"** - Excellent heat resistance due to being adhesive-free → 5% weight loss temperature (534°C) - High adhesion strength achieved through unique polyimide technology → Stainless steel/polyimide adhesion strength (2.4 kN/m) - Wide range of thickness options → Stainless steel thickness (15, 18, 20, 30, 50 μm) → Polyimide thickness (selectable between 5-25 μm) *For examples of properties, please refer to the PDF document or feel free to contact us.*

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!

At Kawamura Industries, we develop and manufacture materials for electronic applications and provide associated processing technologies. We will introduce technologies that have a proven track record for substrates used in 5G and for planar heating elements. 【Our Technology: Electronic Materials - Strengths of Vacuum Heat Press Coating Technology】 ■ Vacuum Heat Press In prototype and mass production using vacuum heat 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 press machines, capable of handling various sizes and temperatures. - There are press machines installed in a cleanroom environment. ■ Resin Coating on Metal Foils 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 coatings 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 introductory document summarizing what Kawamura Industries can do! You can view it immediately via [PDF Download].

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.
