Door and window hinges are hardware accessories used to connect door and window leaves and frames, and their design and quality directly determine the opening and closing effects of doors and windows. The hinge, through its precise mechanical structure inside, enables the doors and windows to rotate flexibly and stably, bringing great convenience to our lives.

In our daily lives, doors and windows are an important component of our living environment. They not only provide us with ventilation and lighting functions, but also undertake important tasks of protecting our privacy and security. However, the smooth opening and stable performance of doors and windows often rely on a seemingly small but crucial component - the hinge.
