Waterproofing and miniaturization of electrical components in infrastructure equipment! High reliability hot melt molding sealing for protecting automotive electrical components!
As remote communication for meter reading, such as smart meters, and visualization of usage through HEMS advance, the importance of waterproof and dustproof measures for the increasing number of electronic components has grown. Matsumoto Processing proposes waterproof and dustproof protection for electronic components using hot melt molding to address concerns such as "If we ensure waterproofing on the housing, it will become larger!" and "The number of parts and labor during production will increase!" 【POINTS of Hot Melt Molding】 1. High Reliability Hot melt molding sealing has a track record of over 20 years in waterproof and dustproof applications for automotive and aerospace components, boasting high reliability. 2. Extremely Low Molding Pressure Molding is done at an extremely low pressure of 0.3 to 5 MPa, ensuring no damage to the electronic components being sealed. 3. Extremely High Productivity Sealing is completed in one shot within seconds to 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 components 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.
