Piano Hinge Manufacturer In China
The piano hinge is a unique long hinge. It usually has a slender structure that can span the entire length of the connection. Structurally, the piano hinge consists of two rectangular pieces of material connected by a central pin. The part where the pin passes through is called a joint, which allows the two pieces of material to rotate relative to each other to achieve opening and closing.

Piano Hinge
Features Of Piano Hinge
The core features of the piano hinge are its ultra-long integrated design and excellent load-bearing performance, which makes it suitable for large cabinet doors, equipment boxes, etc. Its wide and thick stainless steel or nickel-plated leaf structure can effectively disperse pressure and prevent door panel deformation, while the corrosion-resistant material ensures long-term use in humid environments.


Material Of Piano Hinge
Piano hinges are usually made of high-strength metal materials to meet industrial-grade use requirements. Mainstream materials include 304 stainless steel (strong corrosion resistance, suitable for humid environments), cold-rolled steel (nickel-plated to improve rust resistance) and some copper alloys (both strong and beautiful). Stainless steel is the first choice for ships, laboratory equipment and other scenes due to its outstanding anti-oxidation ability.
Custom Of Piano Hinge
Piano hinges can be customized according to the three core modules of material, size and function provided by customers. In terms of material, it supports different grades of metals such as 304 stainless steel, cold-rolled steel nickel-plated, copper alloy, etc., and can achieve differentiated appearance through surface treatment (such as sandblasting and brushing); the size can be customized to any length, and the width and thickness of the leaf can be flexibly adjusted; the functional module includes special designs such as damping system integration, multi-angle opening and closing limit, and quick disassembly structure. Our customization process includes four stages: demand analysis → 3D drawing confirmation → sample trial production → mass production, and samples will be delivered within 7-15 working days.

Key Applications of Ninesuns Piano Hinge


Ninesuns piano hinge is used in both industrial and civil fields due to its extra-long structure, high load-bearing capacity and durability. In the communications industry, it is used for 5G base station cabinet doors (single hinge can bear more than 50kg) to ensure stability during frequent maintenance; in the shipbuilding field, it relies on the salt spray corrosion resistance of stainless steel and is suitable for container doors; medical equipment such as CT machine protective doors use silent models with damping to achieve smooth and silent opening and closing; in high-end furniture, piano cover plates and integrated cabinet doors use customized hinges to achieve large-span support and precise positioning. For special scenarios such as aerospace instrument cases, a lightweight version of titanium alloy will be selected to reduce the load while ensuring strength. In addition, theater stage machinery, automated production line protective doors, etc. also generally use modularly designed piano hinges to meet high-intensity and high-frequency use requirements.
