Waterproof insulation for substrates and electrical components. Sample gift of "hot melt molding."
Hot melt molding, low pressure molding, sealing, potting, coating.
"Hot melt molding," which is increasingly being adopted for waterproofing and insulating sealing of substrates and electronic components. We are offering a sample of an LED substrate sealed with hot melt molding for free.
We will provide a sample of a 20×20mm substrate (with LED) molded and sealed with amber/black polyamide-based hot melt free of charge. Please feel free to check the texture in person. Additionally, a movie of the production of this sample is currently available on the YouTube video below. If you would like a sample, please do not hesitate to contact us. What is "hot melt molding"? It is a sealing method that uses a solvent-free, one-component thermoplastic adhesive to insert mold electronic components within a mold. It excels in environmental resistance characteristics such as waterproofing, dustproofing, and insulation, and it solidifies in a short time of just a few seconds, leading to its expanding adoption as a sealing method alternative to potting. Furthermore, the materials used in this method are primarily derived from natural fatty acids sourced from grains, making it an environmentally sustainable method. Examples of applications: - Automotive electronic components (interior/exterior of vehicles) - Electronic components for power tools - Electronic components for industrial equipment - Various sensors, switches, etc. - Components for outdoor equipment (such as agricultural machinery)

Company information
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.
