1. Spring hinge

Mainly used for cabinet doors, wardrobe doors, it generally requires a thickness of 18-20mm. In terms of material, it can be divided into: galvanized iron, zinc alloy. In terms of performance, it can be divided into two types: holes that need to be drilled and holes that do not need to be drilled. No need to punch holes is what we call bridge hinges. The bridge hinge looks like a bridge, so it is commonly known as the bridge hinge. Its characteristic is that it does not need to drill holes in the door panel, and it is not limited by the style. Specifications are: small, medium, large.

Specifications are: &26, &35.There are detachable directional hinges and non-detachable non-directional hinges. For example, the 303 series of Longsheng hinges are detachable directional hinges, while the 204 series are non-detachable spring hinges that can be divided in shape: full cover (or straight arm, straight bending) half cover (or curved arm, middle Bend) The inner (or big bend, big bend) hinge is attached with adjustment screws, which can adjust the height and thickness of the board up and down, left and right, the distance between the two screw fixing holes on the side of the hole is generally 32mm, and the distance between the diameter side and the two sides of the board is 4mm (painting). In addition, spring hinges also have various special specifications, such as: inner 45-degree angle hinge, outer 135-degree angle hinge, and open 175-degree angle hinge.


The difference between the three hinges of right-angle (straight arm), half-bend (half-curve), and big bend (big curve):

Right-angled hinges allow the door to completely cover the side panels;

The half-bent hinge allows the door panel to cover part of the side panel;

Large curved hinges allow the door and side panels to be parallel;

2. Door hinge

It is divided into ordinary type and bearing type. The ordinary type has been mentioned above, and now the focus is on the bearing type. The bearing type can be divided into copper and stainless steel in terms of material. In terms of specifications: 100X75 125X75 150X90 100X100 125X100 150X100 Thickness is 2.5mm, 3mm bearing has two bearings, four bearings. From the point of view of consumption, copper bearing hinges are mostly used because of their beautiful and bright style, moderate price, and equipped with screws.

4. Heavy duty hinges

Due to the particularity of the installation position, the requirements for the hinge are also very large. The general size is more than 150MM, the bearing capacity is large, and the shape structure conforms to the special structure of the cabinet door. It is often used in refrigerators, freezers and other large doors, mostly zinc Alloy material

How to buy

Look at the material and weigh the weight

The quality of the hinge is poor, and the cabinet door is easy to lean forward and backward after being used for a long time, loose and sag. Almost all the cabinet hardware of big brands are made of cold-rolled steel, which is formed by one-time stamping, which has a thick feel and a smooth surface. Moreover, due to the thick surface coating, it is not easy to rust, strong and durable, and has strong load-bearing capacity, while inferior hinges are generally welded with thin iron sheets, which have almost no resilience, and will lose elasticity after a long time, causing the cabinet door to close. Not tight, or even cracked.

experience the feel


Different hinges have different feel when used. A hinge with excellent quality has a softer force when opening the cabinet door. When it is closed to 15 degrees, it will automatically rebound, and the rebound force is very uniform. Consumers can switch cabinet doors more and more when purchasing to experience the feel.View details

The details can see whether the product is good or not, so as to confirm whether the quality is outstanding. The hardware used in high-quality wardrobe hardware has a thick feel, a smooth surface, and even achieves a mute effect in design. Inferior hardware is generally made of cheap metals such as thin iron sheets, and the cabinet door is stretched and jerky, and even has a harsh sound.

In addition to the visual inspection and the smooth and smooth surface of the hinge when selecting a hinge, attention should be paid to the reset performance of the hinge spring. The quality of the reed also determines the opening angle of the door panel. A good quality reed can make the opening angle exceed 90 degrees.



The hinge can be opened 95 degrees, and the two sides of the hinge can be pressed firmly by hand to observe that the supporting spring sheet is not deformed or broken, and the very strong product is of qualified quality. Inferior hinges have a short service life and are easy to fall off, such as cabinet doors and hanging cabinets falling off, mostly due to poor hinge quality.
