This waterproof button features silicone overmolding produced via an injection molding process. First, the plastic housing is placed into the mold. Liquid silicone raw materials—supplied in separate A and B containers on the injection molding machine—are drawn through conduits, mixed, and injected directly into the mold, followed by high-temperature vulcanization.
Customization options include screen-printed characters, wear-resistant coatings, and backlit/translucent designs. The button is suitable for low-light or night-vision environments, offering distinct tactile feedback; travel distance and actuation force can be adjusted to meet specific operational requirements for night-vision equipment.
The injection molding process achieves IP67/IP68 dust and water resistance ratings, effectively preventing rain, dew, mud, and sand from penetrating the internal circuitry of the night-vision device, thereby meeting the demands of all-weather outdoor use. The automated production process offers faster cycle times compared to other methods, making it particularly well-suited for high-volume production of small-to-medium-sized products.
1.These waterproof silicone buttons feature an integrated over-molding design that combines silicone with plastic. High-quality liquid silicone is used for the outer layer, offering excellent elasticity, flexibility, and skin-friendliness, alongside being eco-friendly, non-toxic, and odorless; the plastic component provides superior chemical stability and corrosion resistance.
2.The materials offer excellent electrical insulation, low density, and light weight, as well as outstanding resistance to temperature extremes, UV radiation, and oil, significantly extending the product's service life.
3.The rigid plastic base resists deformation and impact, solving common issues with pure silicone buttons such as structural collapse and poor alignment. Meanwhile, the soft, resilient silicone outer layer ensures a comfortable tactile feel and smooth operation—preventing sticking during repeated, long-term use—and delivers a lifespan far exceeding that of standard plastic buttons.
Shenzhen ES Electronic Co., Ltd. offers custom mold-making and manufacturing solutions for silicone-over-plastic buttons designed for equipment used in night reconnaissance, outdoor exploration, and security surveillance.
