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.

Separate meeting.

Free collection of case studies and technical materials packed with tips and know-how for improving processes related to waterproofing, dustproofing, and insulation of implementation substrates!

Our company provides comprehensive support from the initial technical discussions and prototype production and evaluation, to the examination of optimal processes for mass production, equipment proposals, design and manufacturing of dedicated machines (automated systems), supply of resin materials, and line support. Additionally, for customers who find it difficult to introduce equipment, we offer contract manufacturing services at our factory. 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 if it's just for a tour.

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.

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.

"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.

Forming and sealing electronic components with a one-component thermoplastic adhesive that is free of unnecessary agents. By sealing and forming with the adhesive, it firmly adheres to the substrate (such as printed circuit boards) and prevents water intrusion. The material has a proven track record of use in environments ranging from -40°C to 150°C. Matsumoto Processing is capable of forming and sealing using hot melts based on polyamide, polyolefin, polyurethane, and polyester. Matsumoto Processing will propose the optimal hot melt, perform shape modeling, analysis verification, and prototype creation based on the characteristics required by the customer's product. For customers wishing to implement the process in-house, we provide comprehensive support including the production of forming machines, molds, development of forming conditions, startup assistance, and supply of hot melts. For customers who wish to outsource hot melt forming, we offer hot melt forming contract services at Matsumoto Processing's factory.
