Instructions for purchasing door hinge

Hinge, also known as hinge, is an important component for opening and closing various door leaves. It not only needs to bear the weight of the door panel alone, but also needs to maintain a flat exterior view. In the frequent use of door leaves in daily life, the hinge is the most tested. Improper selection of hinges may cause deformation of the door panel and uneven seams after a period of use.

Hinges are divided into lifting hinges, ordinary hinges, glass hinges, pipe hinges, hydraulic support arms, etc. according to their purpose. Stainless steel, copper, alloy, plastic, and cast iron can all be used in the production of hinges. Relatively speaking, steel hinges are the best quality and most widely used among various materials, especially those made of cold-rolled steel, which have better toughness and durability.

In addition, hinges with multiple braking positions should be selected as much as possible. The so-called multi-point positioning, also known as "random stop", refers to the door leaf being able to stay at any angle position when opened, without automatic rebound, thus ensuring convenience of use. It is particularly necessary to use multi-point positioning hinges for the upward facing cabinet ceiling doors.

The quality of the hinge mainly depends on the quality of the bearing. Generally speaking, the larger the bearing diameter, the better. The thicker the wall panel, the better. In addition, it can be opened, closed, and pulled several times, making it easy to open, noise free, and flexible.
