Hot Melt Molding Case Study: "LED Module Waterproof Sealing"
LED module waterproof sealing! A case of process improvement through switching from potting.
Hot melt molding is a molding technology that involves injecting a solvent-free, one-component thermoplastic hot melt adhesive into a mold under low pressure. This method is widely used for purposes such as dust-proofing, waterproofing, vibration resistance, impact resistance, insulation, and housing functionality. In this catalog, we introduce a case where the process was improved by switching from potting to hot melt molding for waterproof sealing of LED modules. 【Conventional Method: Silicone Potting】 - A bathtub for polycarbonate molded products is created. - The module is placed in the case and secured. - Silicone resin is poured in and cured by heating for 80 minutes. ↓ 【Hot Melt Molding Method】 - Two modules are set on the mold. - Pressing the molding start button completes the sealing in 40 seconds. *For more details, please refer to the catalog or feel free to contact us.

Hot melt molding for waterproofing, dustproofing, and miniaturization of M2M/IOT sensors.
Our company specializes in hot melt technology, specifically "hot melt molding," which is used for low-pressure molding to seal electronic devices. In recent years, we have received a significant number of inquiries for M2M/IOT applications, particularly for sensors installed outdoors and those used in harsh environments, aimed at waterproofing, dustproofing, and insulation. Examples of inquiries: - Sensors for agricultural applications (soil sensors, livestock management sensors) - Sensors for building management - Sensors for monitoring the operational status of outdoor equipment (such as outdoor units) - Drones, etc. Why is hot melt molding gaining attention? - It can mold at low pressure, allowing for sealing even delicate sensors. - Extensive waterproofing and dustproofing experience cultivated through automotive components. - The hot melt used is flame-retardant and UL94 V-0 certified. - The raw materials are derived from natural components (non-petroleum-based) and are environmentally friendly. Matsumoto Processing also accommodates small-batch sealing through a contract production system. Customers with themes related to waterproofing and dustproofing for sensors are encouraged to inquire.
