Hinges

Hinges are mechanical components consisting of two pieces that are connected to a top and bottom, door and post, or any two surfaces that require rotation around a fixed axis point. One piece of the hinge remains stationary while the other rotates around the fixed axis point, allowing for smooth movement of the connected surfaces. There are different types of hinges available, each with unique features catering to specific needs. These include: Concealed hinges: These hinges are hidden from view when the connected surfaces are in a closed position, providing a seamless appearance. They are commonly used in furniture and cabinetry. Elbow hinges: Elbow hinges consist of two plates connected by a pin, allowing for rotation around a single axis. They are typically used in doors, windows, and gates. Knuckle hinges: Also known as butt hinges, knuckle hinges have interlocking knuckles that provide strength and durability for heavy-duty applications. Leaf hinges: Leaf hinges are simple, flat hinges consisting of two leaf-like plates connected by a pin. They can be used in a variety of applications, from small jewelry boxes to large industrial machinery. Lift off hinges: These hinges allow for easy removal of doors or covers without having to unscrew the hinge itself. They are commonly used in electrical enclosures and control panels. Side hinges: Side hinges are attached to the side of the surface they are connecting, rather than the top and bottom. They are often used in folding tables, cabinets, and desks. Hinges are made from various materials, including brass, plastic, polyamide, stainless steel, steel, and zamak (zinc alloy). Brass and stainless steel are commonly used in applications where corrosion resistance is essential, such as marine equipment and outdoor fixtures. Plastic and polyamide hinges are lightweight and cost-effective, making them suitable for use in electronics and consumer goods. Steel and zamak hinges are known for their strength and durability, making them ideal for heavy-duty applications. In summary, hinges are two-piece mechanical components used to connect two surfaces and allow for smooth rotation around a fixed axis point. They come in different types and materials, catering to various needs and requirements. Hinges are essential components in many applications, from furniture to industrial machinery, providing durability, strength, and flexibility.
