Cast iron plate—The heart of the piano.
Steel plates (steel bones), also known as cast iron plates, are made with a unique technique that supports the tension and tonal fundamental frequencies of all strings.
The cast iron plate holds the pins, the key pins of the tight strings, in place, allowing the strings to be tuned to the specified frequency.
The cast iron plate can withstand the tension of all strings close to about 20 tons, and the quality of the steel plate will directly affect the service life of the piano.
The cast iron plate receives the striking note and forms a double resonance, spreading the sound through it to achieve the best timbre.
Vacuum casting—Cast iron plate of topwinner
At present, there are two casting processes for piano cast iron plates: one is the traditional sand turning process, and the other is the vacuum sealing molding casting method.
Compared with the traditional sand casting process, the vacuum cast iron plate of the topwinner piano lays a solid foundation for the stability of the pitch and the improvement of quality.
Strong stability
Vacuum casting has a high degree of precision and can be molded at one time, which not only ensures the stability of the overall quality of the piano, but also reduces the operation and maintenance costs.
It is not easy to deform
The vacuum cast iron plate has high dimensional accuracy without deformation, and the surface is smooth and clear, which is conducive to the resonance of the strings to produce better sound.
The craftsmanship is exquisite
The embossed pattern can be cast on the vacuum cast iron plate to realize the modeling requirements of precision casting and bring a different listening and visual experience.
