Waterproof sealing of substrates, sensors, etc. Hot melt molding.
Low Pressure Molding, Hot Melt Molding, Waterproof and Dustproof, Encapsulation Molding
Complete sealing of electrical components in just a few dozen seconds. Ideal for waterproofing, dustproofing, and insulation! Hot melt molding is gaining attention for the waterproof sealing of electrical components.
I want to use hot melt molding, but... ▼ The equipment is too expensive to adopt. ▼ Since the products are in the range of dozens per lot, we cannot consume the materials. ▼ Due to fluctuations in production quantity, we want to create a buffer through outsourcing. ▼ I want to adopt it immediately, but... I can't wait for the equipment delivery time. We respond to such customer "troubles." Our company applies hot melt molding to parts such as circuit boards entrusted to us and returns them. - We can handle almost all types of molding hot melt materials, including polyamide-based, polyester-based, polyolefin-based, and reactive polyurethane-based. - Materials are kept in standard stock for each grade, minimizing the burden on our customers. Our factory is ISO 9001 certified and also supports encapsulation molding for automotive parts. ◆ Please feel free to contact us.

basic information
Examples of Contract Processing Customer 1: Coil Manufacturer They want to seal large coils for incorporation into equipment using hot melt, but with a production volume of about 10 units per month, they cannot expect to recover the investment even if they introduce a molding machine... → Contract processing with Matsumoto. Customer 2: Electronics Manufacturer They want to seal parts of HEMS-related devices with hot melt. They have a plan that spans a decade for widespread adoption, but for the first five years, the production numbers will be very low, and they want to refrain from capital investment. If production numbers increase steadily after five years, they would like to introduce equipment at that time. → Contract production with Matsumoto. Additionally, Matsumoto, which also handles equipment, provides peace of mind when it comes to equipment introduction. Customer 3: Home Appliance Manufacturer The model life is short, around one year, and they are unsure if the next model will also require hot melt sealing, so they cannot make capital investments. → Contract production with Matsumoto. Customer 4: Lighting Equipment Manufacturer There are significant fluctuations in production quantities, making it impossible to set up processes in-house. → Contract production with Matsumoto.

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.
