Achieving high reliability for outdoor IoT with waterproof and vibration-resistant smart locks through hot melt molding!
Smart locks used in share mobility services, which are becoming more widespread. Exposed to wind and rain outdoors 24 hours a day, 365 days a year, and affected by vibrations during mobility installation, these devices require high reliability. Therefore, Matsumoto Processing proposes the protection of electrical components using "hot melt molding," which has a proven track record in waterproofing and dustproofing automotive electrical parts, to reduce failure rates through improved waterproofing and vibration resistance. 【POINTS of Hot Melt Molding】 1. High Reliability Hot melt molding has over 20 years of proven use in waterproof and dustproof applications for automotive and aircraft parts, boasting high reliability. 2. Extremely Low Molding Pressure Molding is done at an extremely low pressure of 0.3 to 5 MPa, preventing damage to the electrical components being sealed. 3. Extremely High Productivity Sealing is completed in one shot to several tens of seconds, allowing for significant "tact time reduction" compared to potting. 4. Miniaturization and Lightweighting of Products Since it can be molded into shapes that follow the contours of the parts without the need for housing, "miniaturization and lightweighting" are possible. 5. Environmentally Friendly The hot melt products we handle are primarily made from plant fatty acids derived from grains.
