Product Description

Products Description

Car door hinge is commonly known as hinge, the current market common manufacturing process has two kinds of stamping and hot rolling. The main function of the car door hinge is to connect the door and the body, and keep the position of the door relative to the body. There is to facilitate the opening and closing of the door, and the door hinge is composed of at least two parts, one is the body parts connected with the body, the other is the door parts connected with the door. According to the position, it is divided into: body parts, door parts, etc., and according to the structure, it is divided into: page board, rotary arm, etc.

Hot rolling steel door hinges is the production process preferred by many of the world's leading automotive and truck manufacturers. Vehicle hinge profile steel is one kind of hot rolled section steel connecting automobile body and door.
