1. General hinge
It is the general hinge we often say, it can be used for cabinet doors, windows, doors, etc. Hinges can be divided into iron, copper and stainless steel in terms of material. From the specifications, it can be divided into: 2” (50mm), 2.5” (65mm), 3” (75mm), 4” (100mm), 5” (125mm), 6” (150mm), 50-65mm hinges are suitable for Cabinets, closet doors, 75mm for windows and screen doors, 100-150mm for wooden doors and aluminum alloy doors in the gate.

In addition, there are special hinges such as detachable hinges, flag hinges, and H hinges. They can be disassembled and installed according to various special needs of the wooden door. It is very convenient. When used, it is restricted by the direction. There are left and right types.
2. Spring hinge
Mainly used for cabinet doors and closet doors, it generally requires a plate thickness of 18-20mm. From the material point of view, it can be divided into: galvanized iron, zinc alloy. From the performance point of view, it can be divided into two types: holes are required and holes are not required. No need to make holes is what we call bridge hinges. Bridge hinge looks like a bridge, so it is commonly called bridge hinge. Its characteristic is that there is no need to drill holes in the door panel, and it is not limited by style. Specifications are: small, medium, and large. Holes need to be punched, which are spring hinges that are commonly used on cabinet doors. Its characteristics: the door panel must be punched, the style of the door is restricted by the hinge, the door will not be blown open by the wind after it is closed, and there is no need to install various touch spiders. 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. They can be divided in shape: full cover (or straight arm, straight curved) half cover (or curved arm, middle The inner side (or big bend, big bend) hinges are equipped with adjusting 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 punched side is generally 32mm, and the distance between the diameter side and the two sides of the board is 4mm (Drawing pictures). In addition, spring hinges have a variety of special specifications, such as: inner 45 degree angle hinge, outer 135 degree angle hinge, opening 175 degree angle hinge.
The difference between the three hinges of right angle (straight arm), half curve (half curve), and big curve (big curve):
The right-angled hinge allows the door to completely cover the side panel;
Half-curved hinges allow the door panel to cover part of the side panel;
The large curved hinge can make the door panel and the side panel parallel;

Bearing type can be divided into copper and stainless steel in terms of material. From the specifications: 100X75 125X75 150X90 100X100 125X100 150X100 thickness of 2.5mm, 3mm bearings have two bearings, four bearings. From the perspective of consumption, more copper bearing hinges are used, because they are beautiful in style, beautiful, affordable, and equipped with screws.
4. Mechanical and electrical cabinet hinge
It includes nylon hinges with high wear resistance; corrosion-resistant, high-strength zinc alloy hinges and hinges; corrosion-resistant, oxidation-resistant, and high-strength stainless steel hinges, often used in electromechanical cabinet doors, mechanical equipment operation boxes and other products .
5. Heavy hinge
Due to the particularity of the installation position, the requirements for the hinge are also very large. The general size is above 150MM, the bearing capacity is large, and the shape and structure conform to the special structure of the cabinet door. It is often used for large doors such as refrigerators and freezers. Most of them are zinc. Alloy material
6. Shaped hinge
It is also a corner hinge with a large opening angle, which is also widely used in daily use
