For waterproofing and dustproofing electrical components. Sealing completed in just a few seconds. Due to mold forming, there is a high degree of freedom in shape, enabling miniaturization and lightweight design. Hot melt low-pressure molding method.

"Hot melt molding," which is attracting attention as a sealing method to replace potting for the purpose of waterproofing and dustproofing electrical components, has been expanding its adoption starting with automotive parts around 2010 and into various electrical components. We will be introducing various case studies at the "38th Monozukuri World Tokyo" held at Tokyo Big Sight. We sincerely invite you to visit us. We look forward to seeing you there. Event Dates: July 1 (Wed) - 3 (Fri), 2026, 10:00 AM - 5:00 PM Venue: Tokyo Big Sight (International Exhibition Center) Booth Number: East Hall - E25 (within the Shizuoka Prefecture company booth)

Our company provides comprehensive support for the introduction of hot melt molding methods, from initial technical discussions and appropriate hot melt selection to prototype production and evaluation, optimal process considerations for mass production, proposals for optimal equipment or the design and manufacturing of dedicated machines (automated systems), hot melt supply and line support. For customers for whom equipment installation poses a barrier to adopting this method, we even offer production contracting at our facility, ensuring support from "start to finish." **Benefits of Hot Melt Molding** - Improved production efficiency and cost reduction through alternative methods to potting - Greater design flexibility due to mold forming, enabling miniaturization and lightweighting of components - Use of sustainable raw materials derived from natural fatty acids We have various molding machines and displays of adopted products available at our prototype lab in Fuji City, Shizuoka Prefecture. Please feel free to visit, even just for a tour.
