Leading Piano Hinge Manufacturers

Piano hinges, also known as continuous hinges, were created to join two flat surfaces together, typically at a 180-degree angle. These surfaces can be made of a variety of materials, including wood, metal, and plastic. The design of the piano hinge allows for a smooth and even distribution of weight and stress along the entire length of the hinge. The name “piano hinge” comes from its use in piano lids, which require a strong and flexible hinge to withstand the weight of the lid while allowing for easy opening and closing. Today, piano hinges are used in a wide variety of applications beyond pianos, and are a popular choice for many different industries and projects Read More…

Piano Hinges Piano hinges, also known as continuous hinges, are jointed devices that allow an attached part, like a door or window, to swing. Able to provide consistency in strength along the entire length of the hinge, piano hinges support the objects to which they are attached and reduce the gap between the objects and the hinges. Piano hinges are typically longer than standard hinges, usually measuring five inches in length or more, and often span the length of a joint.

Components of Piano Hinges

Piano hinges consist of two leaf plates, connected by a pin that runs the length of the hinge. The leaf plates are the long, flat pieces that are attached to the surfaces being joined. The pin is the cylindrical rod that connects the leaf plates and allows for rotational movement. The knuckles are the cylindrical portions of the hinge that surround the pin and connect the leaf plates. Finally, the flange is the portion of the hinge that is attached to the surface, providing support and stability.

Variations of Piano Hinges

There are several variations of piano hinges, each with unique features and applications. Continuous hinges are the most common type of piano hinge, consisting of a single long piece of metal that runs the length of the joint. Strap hinges are similar to continuous hinges, but are wider and have a more decorative appearance. Concealed hinges are designed to be hidden from view, often used in cabinetry and furniture applications. Specialty hinges include take-apart hinges, which can be easily disassembled, and offset hinges, which allow for the hinge to be offset from the surface it is attached to.

Materials Used for Piano Hinges

Piano hinges are commonly made from stainless steel, brass, aluminum, and plastic. Stainless steel is the most popular material due to its high strength and durability, as well as its resistance to corrosion and rust. Brass is a popular choice for decorative applications due to its attractive appearance, while aluminum is commonly used in lightweight applications such as aerospace and automotive industries. Plastic piano hinges are used for low-stress applications and offer a cost-effective alternative to metal hinges.

Considerations for Piano Hinges

While piano hinges offer many benefits, there are also some limitations to consider. The weight capacity of piano hinges can be a concern, as they are not designed to handle heavy loads. They are also susceptible to rust and corrosion if not made from the proper material, and their flexibility is limited compared to other types of hinges.

Benefits of Piano Hinges

Despite their limitations, piano hinges offer many benefits. They are easy to install and offer a high level of strength and durability. Their aesthetic appeal makes them popular in furniture and decorative applications, and their versatility and flexibility make them useful in a wide variety of industries and applications.
