Waterproof sealing of substrates, sensors, etc. Hot melt 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.

Introducing the waterproof, dustproof, and insulation protection technology for various electrical components called "hot melt molding." Sealing is completed in just a few dozen seconds, achieving process improvement and cost reduction.
The technology "Hot Melt Molding," which is expanding its adoption for waterproofing, dustproofing, and insulation protection of various electrical components, rapidly solidifies thermoplastic hot melt adhesives within molds, completing sealing in a short time of just a few dozen seconds. Compared to traditional urethane potting and epoxy potting, this technology allows for sealing to be completed in an ultra-short time, leading to alternatives aimed at process improvement and cost reduction. Additionally, because it involves mold forming, it offers high freedom of shape, receiving high praise for miniaturization and lightweighting of components. Our company, Matsumoto Processing, has been involved in the protection of many electrical components, including automotive electrical components, as a pioneer of this technology alongside our customers. We can achieve material selection, specification consideration, prototype shape design, mold manufacturing, and prototyping in a short time. Customers interested in this technology are encouraged to feel free to contact us.

For waterproofing, dustproofing, and insulation of electrical components. The spotlight is on the sealing technology "Hot Melt Molding." Complete sealing of electrical components is achieved in just a few seconds.
"Complete sealing of electrical components in just a few dozen seconds. Ideal for waterproofing, dustproofing, and insulation!" Hot melt molding, which is gaining attention for waterproof sealing of electrical components, uses thermoplastic adhesives in low-pressure insert molding to achieve environmental protection such as waterproofing and dustproofing for electrical components like mounted circuit boards. Compared to traditional two-component potting and conformal coating, sealing is completed in an extremely short time, leading to an expansion in its adoption as a sealing technology. Now, at Matsumoto Processing Lab, nine hot melt molding machines are installed, and you can observe the process of hot melt sealing electrical components. Customers wishing to visit are encouraged to inquire.

For waterproofing, dustproofing, and insulation of electrical components. We present a small desktop molding device for the spotlighted sealing technology "hot melt molding" in a video. Complete sealing of electrical components is achieved in just a few seconds.
"Complete sealing of electronic components in just a few dozen seconds. Ideal for waterproofing, dustproofing, and insulation!" Hot melt molding, which is gaining attention for waterproof sealing of electronic components, is a technology that achieves environmental protection such as waterproofing and dustproofing by low-pressure insert molding of thermoplastic adhesives onto electronic components like mounted circuit boards. Compared to traditional two-component potting and conformal coating, sealing is completed in an extremely short time, leading to an expansion in the adoption of this sealing technology. Now, our company, Matsumoto Processing, is selling a compact tabletop molding device for hot melt molding called the "MK500." We have introduced this machine in a video on YouTube. Please take a look. (You can watch the video via the link below.) Thank you very much for your attention.

Sustainable electrical component sealing technology "Hot Melt Molding." Suitable for waterproofing and insulation of electrical components. Achieves complete sealing in a short time.
"Complete sealing of electrical components in just a few dozen seconds. Ideal for waterproofing, dustproofing, and insulation!" Hot melt molding, which is gaining attention for waterproof sealing of electrical components, uses thermoplastic adhesives in low-pressure insert molding to achieve environmental protection such as waterproofing and dustproofing for electrical components like mounted circuit boards. Compared to traditional two-component potting and conformal coating, sealing is completed in an extremely short time, leading to its expanded adoption as a sealing technology. Additionally, due to the following features, it is also gaining attention as a sustainable sealing method: - The hot melt we handle is a solvent-free, one-component hot melt made primarily from plant-derived natural fatty acids. - The process does not require heating during the curing process, making it an energy-efficient operation. Now, at the Matsumoto Processing Lab, nine hot melt molding machines are installed, and it is possible to observe the actual process of hot melt sealing of electrical components. Customers interested in observing are encouraged to inquire.
