Hot Melt Molding Case Study: "Waterproof Connector"
Introduction to the hot melt molding method that completes 4 waterproof connectors in 30 seconds.
Hot melt molding is a molding technique that involves injecting a solvent-free, one-component thermoplastic hot melt adhesive into a mold at low pressure. This method is widely used for purposes such as dustproofing, waterproofing, vibration resistance, impact resistance, insulation, and housing functionality. In this catalog, we introduce examples of process improvement and value analysis through the switch from waterproof connector rubber bushings. [Challenge] We want to waterproof the wire insertion area. *For more details, please refer to the catalog or feel free to contact us.
basic information
<Conventional Method Rubber Bush> - Pass the rubber bush through the core wire before crimping the terminal. Insert it into the connector. - The rubber bush becomes an obstacle, making automatic terminal crimping impossible, so the more cores there are, the more difficult the work becomes. ↓ <Hot Melt Molding> - No rubber bush required. - After crimping the terminal with an automatic machine, insert it into the connector. Arrange 4 of them on the mold and start the cycle. - 4 waterproof connectors are completed in 30 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.
