Product Introduction

Key Features

Concealed Design

• The concealed design of this rotary damper hinge is a key aspect that preserves the aesthetic integrity of the piano. It is carefully engineered to be hidden within the structure of the piano cover and the body, ensuring that it does not detract from the overall visual appeal of the instrument. This is especially important for high-end and luxury pianos where the appearance is as crucial as the performance. The concealed hinge allows the piano to maintain its classic and refined look, while still benefiting from the advanced damping functionality. It seamlessly integrates into the wooden framework, giving the impression of a traditional piano with enhanced modern features.
• The compact size and discreet placement of the hinge components make it possible to achieve a concealed design without sacrificing performance. It is designed to fit snugly within the available space, without causing any protrusions or obstructions.

Slow Down/Upright Hydraulic Damping

• The slow down/upright hydraulic damping system is at the core of this hinge's functionality. When the piano cover is being opened or closed, the hydraulic mechanism gradually slows down the rotational speed, providing a gentle and controlled motion. This is essential for protecting the piano cover and the body from damage caused by sudden impacts or excessive force. For example, when closing the cover, the slow-down effect prevents it from slamming shut, which could scratch the finish or cause misalignment of the internal components. The upright hydraulic damping also ensures that the cover remains in a stable position when opened, eliminating any wobbling or sagging. The damping force can be adjusted to match the specific weight and size of the piano cover, ensuring optimal performance for different piano models.
• The hydraulic system is designed to be highly reliable and consistent. It can withstand the rigors of continuous use and maintain its performance over time, providing a seamless user experience every time the piano cover is operated.

Wooden Construction

• The use of wooden materials in the construction of this rotary damper hinge adds a touch of warmth and elegance to the piano. The wood is carefully selected for its durability and aesthetic qualities, ensuring that it complements the overall design of the instrument. It is also finished to match the color and texture of the piano, creating a cohesive and harmonious look. The wooden construction not only enhances the visual appeal but also provides a certain level of insulation and resonance characteristics that are beneficial for the overall sound quality of the piano. It is a testament to the craftsmanship and attention to detail that goes into creating a high-quality piano accessory.
• The wooden components are treated to resist warping, cracking, and other forms of damage that could occur due to changes in humidity and temperature. This ensures the long-term stability and functionality of the hinge.

Customizable for Piano Covers

• This rotary damper hinge is highly customizable to fit the unique requirements of different piano cover designs. The torque and damping force can be adjusted to match the size, weight, and movement characteristics of the cover. The overall dimensions and appearance of the hinge can also be tailored to blend in with the specific style of the piano, whether it is a grand piano, an upright piano, or a specialty piano design. The mounting options and connection points are designed to be flexible, allowing for easy installation onto the piano's frame and cover. The hinge can be attached using screws, clips, or other fastening methods, depending on the specific design of the piano.
• Additionally, the speed and sensitivity of the slow down/upright hydraulic damping can be fine-tuned. This allows for a customized user experience. A slower and more controlled movement can add a touch of luxury and refinement to the operation of the piano cover, while a slightly faster setting can be more practical for a busy performance or rehearsal environment.

Installation and Maintenance

• Installation: The installation process is straightforward. The hinge is attached to the piano cover and the body using simple screws or clips, depending on the specific design. Clear installation instructions are provided to ensure proper alignment and connection.
• Maintenance: Regular inspection of the hinge for any signs of wear, such as leakage of hydraulic fluid, loose parts, or a decrease in damping performance, is recommended. If any issues are detected, the hinge can be easily replaced. Cleaning the hinge with a mild detergent and a soft cloth is sufficient to keep it in good working condition.
