S-SEN Metal manufactures and supplies door closers that are hydraulically based door control devices that enable smooth, automatic door closing, reducing impact, protecting the door and frame, and extending their lifespan. We offer a variety of styles and materials suitable for commercial buildings, public facilities, and residential homes. As a professional S-SEN door closer manufacturer and supplier in China, we provide consistent quality and customized services to meet the engineering and home needs of global buyers.
The S-SEN door closer uses a hydraulic system as its core, with built-in precision components such as return springs and transmission gears to ensure smooth door closing. When the door opens, the return spring is compressed, driving the hydraulic fluid flow; after the door is fully opened, the spring releases its potential energy, and the hydraulic fluid slowly flows back through a throttling structure to create damping, preventing the door from closing quickly due to wind or impact. The entire process is smooth and quiet.
The S-SEN factory's Door Closer utilizes a hydraulic system with a built-in precision return spring and transmission gears. When the door opens, the return spring is compressed, propelling the hydraulic oil. Once fully open, the spring releases energy, and the hydraulic oil slowly returns through a throttling structure, achieving a soft, controlled closure and preventing rapid closing due to wind or impact. The entire process is smooth and quiet, suitable for various environments.
