What is a hinge:
.,.,,.
A hinge is a device used to connect two objects and allow them to rotate relative to each other. Hinges are typically composed of rotational connections on two planes, enabling the two objects to rotate around a common axis. They have a wide range of applications across various uses, from furniture and doors/windows to mechanical equipment and industrial structures.
,.,,.,,,.
The primary function of hinges is to provide a rotational connection, enabling two objects to rotate relative to each other in one or more planes. This rotation can be unidirectional or bidirectional, depending on the design of the hinge. Hinges can be employed to achieve different types of motion, such as opening, swinging, tilting, and more.

Types of hinges:
,,.:
According to different needs and applications, hinges come in various shapes, sizes, and materials. Some common types of hinges include:
Surface-mounted hinge:
,,.
Surface-mounted hinge:
Surface-mounted hinges are a type of hinge commonly used in various industrial equipment such as industrial enclosures, cold storage units, and refrigeration cabinets. Their distinguishing feature is that a portion of the hinge is exposed on the exterior.
Concealed Hinge:.,.
Concealed Hinge: Used to connect and facilitate the opening and closing of swinging doors or windows. It can be completely hidden within the door frame or window frame when closed, providing a more aesthetically pleasing appearance.
:,.,,.
Sleeve hinge: A sleeve hinge, also known as a bushing hinge, is characterized by the addition of a sleeve to the hinge. The sleeve contains bearings or rollers internally, enabling smoother and more seamless rotation of the hinge.
:,,,,.
Heavy-Duty Load-Bearing Hinge: A heavy-duty load-bearing hinge is a type of hinge used to connect oversized heavy doors, windows, ships, mechanical equipment, and more. It is characterized by its strong load-bearing capacity and high durability.
:,,.,,,,.
Torque Hinge: A torque hinge is a mechanical component used to connect two objects and enable them to rotate. They can be employed in various applications, such as doors, hatches, lids, and even in industrial and commercial settings where support for weight and greater forces and torques is required.
:.,,,,,.
Convex Door Corner Hinge: A convex door corner hinge is a type of hinge used for large door leaves or panels. It's a hinge characterized by its simple structure and strong load-bearing capacity, commonly employed in large equipment such as door panels, ships, bridges, machinery, and other sizable applications.
:(Detachable Hinge),,.,,,.
Detachable Hinge: A detachable hinge, also known as a Detachable Hinge, is a type of hinge that can be easily taken apart. Its primary purpose is to connect and support two objects while allowing for straightforward disassembly. Detachable hinges find widespread use in various fields such as furniture, doors, windows, vehicles, etc., due to their convenience for maintenance and replacement purposes.
,,.,,,.
These are just a few examples of hinge types; in reality, there are many other variations and types that cater to different applications and scenarios. Regardless of the hinge type, they all need to balance rotational connectivity and motion with considerations for safety, durability, and appropriate material selection.

Hinge materials:
,.:
The selection of materials for hinges depends on their specific purpose, environmental conditions, and load requirements. Here are some common hinge materials and their characteristics:
: ,,.(304).
Steel: Steel is one of the most common hinge materials due to its good strength, durability, and corrosion resistance. Stainless steel (such as 304) is well-suited for applications requiring high corrosion resistance.
: ,,.
Aluminum Alloy: Aluminum alloys are lightweight and possess good corrosion resistance. They are often used in applications where weight reduction is important, such as the aerospace and automotive industries.
: ,.
Zinc Alloy: Zinc alloys have moderate strength and corrosion resistance, suitable for some medium-load applications.
:,,,,,,..
Cold-rolled sheet: Cold-rolled sheet is widely used, such as automobile manufacturing, electrical products, rolling stock, aviation, precision instruments, food cans and so on. Cold-rolled sheet steel is the abbreviation of ordinary carbon structural steel cold-rolled sheet.
POM:,,,,,.
Polyformaldehyde POM: methylene oxide, polyacetal, steel, is a thermoplastic used in engineering, suitable for high rigidity, low friction and excellent dimensional stabi.
,:
Therefore, when choosing hinge materials, the following factors need to be considered:
: ,.
Load Requirements: Select the appropriate strength grade of material based on the weight and forces that the hinge needs to bear.
: ,,.
Environmental Conditions: Consider the environment in which the hinge will be placed, whether it will be exposed to factors like corrosion, humidity, or high temperatures.
: ,.
Durability: Choose a material that suits the required lifespan of the hinge.
: ,.
Aesthetic Requirements: For indoor furniture or decorative applications, materials with better aesthetics can be chosen.
: .
Cost: The cost of materials is also an important consideration.
