We are exhibiting at the "Mie Prefecture Manufacturing Companies Virtual Exhibition" held from February 1 to 28, 2023.

We perform high-precision slitting of various materials according to their intended purpose.

At Kawamura Industries, we have been performing slitting processes on insulating paper, plastic films, and metal foils since our founding. We can customize processing according to various environments, including general and clean environments (clean class = 1,000), and we select processing methods that do not produce burrs or slitting debris based on the materials used. **Features of Kawamura Industries' "Slitting Process"** - Supports high-precision slitting with a width tolerance of less than 20μm - Equipped with a yellow room, allowing slitting of photosensitive materials - Slitting can be performed after laminating backup films or protective films *For processing conditions, please refer to the PDF document or feel free to contact us.*

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.*

By simply dissolving the powder in a solvent and drying it, you can obtain a transparent and high-heat-resistant polyimide film!

Kawamura Industries' "KPI-MX300F" is a polyimide powder material that can dissolve in various solvents. The films obtained by dissolving in a solvent and then heating and drying have minimal coloring and high transparency, which is a significant feature. **Features of Kawamura Industries' "KPI-MX300F"** - Can dissolve in various solvents - Produces transparent, high-heat-resistant polyimide films - The resulting films have minimal coloring and high transparency *For property values, please refer to the PDF document or feel free to contact us.*
