Waterproof sealing of substrates: Differences between traditional methods and hot melt molding methods.

"Hot melt molding," which solidifies in just a few dozen seconds and is attracting attention as a waterproof sealing method for electrical components. Our company will be exhibiting at Internepcon Japan (Autumn) from September 9 (Wednesday) to September 11 (Friday). On that day, we will showcase actual electrical components that have adopted hot melt molding both domestically and internationally. We look forward to your visit. We sincerely await your attendance.

Matsumoto Processing will exhibit at the Manufacturing World Tokyo 2026. On that day, we will showcase products that have adopted hot melt molding sealing both domestically and internationally. We sincerely look forward to your visit.

"Free Sample Presentation Campaign" This time, we are offering free samples of our LED-equipped boards that have been completely sealed using hot melt molding to customers who request them. Please feel free to take a look at the actual product. "What is Hot Melt Molding?" It is a groundbreaking sealing method that provides excellent waterproofing, dustproofing, and insulation by injecting thermoplastic adhesive around electronic components. Since it solidifies within seconds in the mold, sealing is completed in a shorter time compared to traditional two-component potting and BMC molding. Additionally, the hot melt we handle is primarily made from natural fatty acids derived from grains, making it highly sustainable. Customers who wish to receive a sample, please do not hesitate 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. This technology achieves environmental protection such as waterproofing and dustproofing by low-pressure insert molding of thermoplastic adhesives on 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 its adoption as a sealing technology. We have succinctly summarized the sealing process in a one-minute video. You can watch it through the related links below. Please take a look!
