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.

●What is Hot Melt Molding? It is a technology that demonstrates excellent sealing performance by directly injecting hot melt adhesive into electronic components. □Advantages of Adoption 1. Reduction in Processing Time Hot melt molding completes one molding cycle in about 10 seconds to several tens of seconds. Unlike potting, there is no need for curing time. 2. Reduction in the Number of Parts Unlike potting, hot melt molding does not require a case. This allows for a reduction in the number of parts and production processes. 3. Reduction in the Amount of Resin Used Hot melt molding can be shaped with minimal thickness that conforms to the inserted components. At Matsumoto Processing, we respond quickly to the reliability requirements of our customers' products by proposing optimal hot melts, modeling sealing shapes, designing and manufacturing molds, and prototyping. For customers wishing to introduce hot melt molding processes in-house, we provide comprehensive support including the manufacturing and sale of molding machines and molds, development of molding parameters, process startup assistance, and supply of hot melt adhesives. Additionally, for customers who wish to outsource hot melt sealing, we offer contract molding services.

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.
