Reasons and solutions for abnormal noise of hinges_Hinge Knowledge

The hinge serves as a vital component that connects the door and door frame, providing support and enhancing security. Depending on the type of door, hinges are available in two main categories: external and built-in hinges. External hinges are suitable for inward-opening doors, while built-in hinges are ideal for outward-opening doors. When made of steel plate, the closed edge of the hinge must be welded to ensure optimal performance. However, sometimes hinges may produce abnormal noise, and it is essential to understand the causes and find effective solutions.

There are several reasons for abnormal hinge noise. One common cause is the infiltration of damp air or dust into the hinge box, leading to friction between the hinge and the hinge pin. This friction generates noise. Another reason could be improper adjustment of hinge screws, resulting in misaligned hinge pins. Additionally, if the hinge fixing screw is not adequately tightened, the hinge may be displaced from its axis over time due to the force of gravity when the door is being used.

Fortunately, solving abnormal hinge noise issues can be relatively straightforward. By correctly adjusting the hinge screws, ensuring that the hinge pins align perfectly on the same axis, you can eliminate noise. For instance, loosening the two screws of the middle hinge of the door frame can help achieve this alignment. Another solution involves lubricating the hinge pin with liquid lubricating oil or butter. However, it is crucial to avoid using vegetable oil or any similar substances such as lard or soybean oil.
