The material selection of automotive door hinge bracket mainly depends on the design weight requirements of the door and the specific parameters of the installation position. For lightweight doors, the use of stamped steel is sufficient to meet the requirements; For heavier doors, it is more appropriate to choose cast steel parts to ensure stability and durability.
The principle of a car door hinge is a mechanical device that connects two solid objects and allows for relative rotation between them. It is usually constructed of movable components, or of materials that can be folded. In order to provide a better use experience, modern cars also use hydraulic hinges (also known as damping hinges), which achieve buffering function through hydraulic damping technology to reduce the noise and impact force when the cabinet door is closed. The working principle of the hydraulic hinge is to convert the oil pressure into mechanical force through the hydraulic cylinder, so that the movement between the door and the cabinet is more stable
