Waterproof sealing of electrical components: Hot melt molding

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.

"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.

"Complete sealing of small motors in just a few dozen seconds. Ideal for waterproofing, dustproofing, and insulation!" Hot melt molding, which is gaining attention for waterproof sealing of small motors, is a technology that achieves environmental protection such as waterproofing and dustproofing by low-pressure insert molding of thermoplastic adhesives. Compared to traditional thermosetting resin sealing, two-component potting, and conformal coating, sealing is completed in an extremely short time, leading to its expanded adoption as a sealing technology. If you are considering waterproof sealing and protection for small motors, please feel free to contact us.

"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.
