Waterproof and dustproof sealing in 30 seconds! Enhancing the long-term reliability of security devices.
"Protect security equipment from rain, condensation, and dust" - High-reliability hot melt molding that achieves waterproof, dustproof, and vibration-resistant properties!!
In security devices that require stable operation 24 hours a day, 365 days a year, ensuring long-term reliability is crucial to prevent failures caused by environmental factors such as rain, condensation, and dust. Hot melt molding achieves high waterproofing, dustproofing, and vibration resistance by directly sealing electronic units. It protects electronic components from external environments while also contributing to miniaturization and weight reduction. Furthermore, by reducing potting processes and waterproof cases, it helps to minimize the number of parts and labor, leading to reduced manufacturing costs. **POINTS of Hot Melt Molding** 1. High Reliability It has over 20 years of proven use in waterproof and dustproof applications for automotive and aircraft parts, boasting high reliability. 2. Gentle Low-Pressure Molding for Electronic Components Molding is done at extremely low pressures of 0.3 to 5 MPa, preventing damage to the sealed electronic components. 3. Excellent Productivity Sealing is completed in just a few dozen seconds per shot, allowing for significant "tact time reduction" compared to potting. 4. Miniaturization and Weight Reduction It enables "miniaturization and weight reduction" by allowing molding that conforms to the components without the need for housing. 5. Environmentally Friendly It uses hot melt materials primarily made from plant-based raw materials, contributing to reduced environmental impact.
basic information
○ Do you have any of the following concerns? - I want to prevent circuit board failures caused by rainwater or condensation when installed outdoors. - I want to improve reliability in high-humidity environments. - I want to reduce the risk of failure due to drops or impacts. - I have many components such as waterproof cases and sealing parts, and I want to reduce costs. - The curing time in the potting process is long, and improving productivity is an issue. - I want to promote miniaturization and lightweighting of components. etc. Hot melt molding is an effective sealing and protection method for solving these issues. ○ Examples of achievable performance Waterproof and dustproof achievements: up to IP67,68 Operating temperature: -40 to 150℃ Flame retardancy: UL94 V-0 etc. It provides various environmental resistance features such as waterproofing, dustproofing, insulation, vibration resistance, and explosion-proofing. At Matsumoto Processing, we select hot melt materials tailored to your product specifications and usage environment, and we handle everything from modeling to prototyping and evaluation. Additionally, we offer support for in-house production, including equipment installation, mold making, optimization of molding conditions, and mass production startup, as well as contract molding services, providing consistent support from prototyping to mass production. Please feel free to consult with us.
