【Sample Giveaway】We are offering free samples of products that apply hot melt molding, a waterproof sealing method for electrical components that replaces potting, to LED substrates.

"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)

Complete sealing of electrical components in just a few dozen seconds. Waterproof, dustproof, and insulated. We will introduce the introduction process and case studies of hot melt molding in a 5-minute video.

"Hot melt molding," which is expanding as a waterproof sealing method for electrical components to replace potting. Compared to traditional two-component potting, the following advantages are being recognized, leading to its adoption: - Extremely short curing time. Hot melt molding completes sealing in just a few seconds. - Possibility of miniaturization and lightweight design. Since hot melt molding is directly insert molded into electrical components, it eliminates the need for a case, allowing for greater design freedom and achieving miniaturization and lightweight construction. - Sustainable materials. The PA-based hot melt we handle is derived from natural plant oils and is environmentally friendly. We have compiled the process for adopting hot melt molding and examples of adopted products into a video of about five minutes. Please check the video link below.

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 on the base material. Repairs can be carried out even 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.

Our company sells PDCE devices and the supports and fittings for installing these devices in various locations. The new lightning rod "PDCE Lightning Ball" is designed to "avoid" lightning strikes by incorporating features that make it difficult for lightning to approach, unlike traditional lightning rods. Its round shape and double structure with an insulator help suppress "welcoming discharge," which attracts lightning current. This lightning protection system complies with the lightning reception requirements of the "Building Standards Act." Rakurai Yokusei Systems Co., Ltd. https://www.rakurai-yokusei.jp/
