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.*

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

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 you require a detailed technical explanation, please contact us.

● 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.
