Schwarzwald Schwarzwald Piano Production and Characteristics
ABEL/FFW hammers made in Germany are used, and the world's top materials are carefully designed in key parts to ensure the high-quality sound quality is full and round.
Schwarzwald Schwarzwald piano uses materials and components that can produce the best sound. Wood is processed under stress and adopts a pure wood rivet connection structure: only in this way can the best acoustic quality be produced. Schwarzwald Schwarzwald piano has ensured the invariable sound characteristics with its unique product quality decades later. The unique sound, almost limitless and colorful timbre, develops a wide range of musical styles; Schwarzwald Schwarzwald piano not only has the ideal timbre for classical music, but also can be used for jazz, rock and pop music.
The back frame and cast iron plate of the piano need to bear the strong tension from the strings. When the audio frequency reaches 440 Hz, the tension will even increase to 20 tons. The pre topped sound board is firmly adhered to the resonator, and the cast iron plate is just on it. The circumferential fixing strip or the iron plate frame made of red beech wood are installed strictly according to the curvature of the sound plate, which makes the iron plate fixed at the right height. This design enables the vibration of all the spectrum emitted by the strings to be amplified freely by the sound board without being absorbed by the heavy components it is loaded. Such a system can ensure that the vibration of the strings can be transmitted more completely without any obstruction and loss of tone. The inner wall frame is made of 18 layers of hardwood plywood. When connected to the peripheral frame, the whole horizontal piano will use 28 layers of hardwood plywood. The strong back pillar transmits the tension from the surrounding frame to the crossbeam. These pillars use red beech hardwood as the core, and pine wood is pasted around the core. This process makes the humidity change unable to have any impact on it, and ensures that it is consistent with the fixed bolts of the iron plate frame for a long time and closely. The fan-shaped arrangement of the back columns plays a role in strengthening the enclosure frame, so that it will not be deformed due to external forces. The steel plate is subject to tension from the strings, so it must be firmly connected to the inner frame structurally. The steel plate should not only have an attractive and timeless design, but also be able to affect the sound effect of the instrument. All steel plates are assembled indoors. This means that more than 600 manual drilling holes for the installation of hanging pins, code pins, chord shafts and bolts need to use a variety of control measures to ensure their precision. The special function of the chord board is to serve as the base of the chord and fix them tightly, so that the tension from the strings can be supported during tuning.
The string striking machine part includes the string striking machine itself and the sound brake component. Therefore, the keyboard rack should be carefully installed on the middle disk to ensure the best performance. The middle plate is made of red beech wood and pine wood by alternating pressing. The high stability achieved enables the instrument not to be affected by humidity changes and long-term use. The natural sun colored advanced calf leather sound head pad installed on the top of the keyboard holder can ensure that the keys move quietly. This sturdy construction also makes the calibration of the Renner string player and keys durable. In order to make the hammer strike the most beautiful sound, the elasticity of the felt pad will be adjusted in time according to the needs of the instrument. Schwarzwald Schwarzwald piano realized through this step. Use special techniques to adjust the hardness and elasticity of each hammer. The density and size of the mallet is also a crucial link that the tuner must deal with in this process. Large scale mallets made of traditional inner and outer felt pads can keep the mallet elastic and stable, thus producing full timbre.
The combination of all these factors has become the basis for the manufacture of durable and finely adjusted mallets.
Thousands of timbers have been piled up outdoors for more than a few years. After repeated drying in the shade and sunshine in spring, summer, autumn and winter, the excess oil contained in the timbers has been naturally dried, and then the deformed parts of the timbers have been removed. What remains is the best wood for making pianos. Each batch of wood is marked with a drying period. The sound board production is based on the natural climate of the user's region to select the appropriate production month. After completion, it shall be placed in a confined space for constant temperature and humidity treatment for half a year. The paint formulation of sound board is kept secret.
Upright piano
Like most German piano factories, the hammer of the "Schwarzwald" piano is also used in the German "Renault". The relationship between the hardness of the hammer felt and the striking point and the sound quality is very important. A piano often needs 2-3 hours of striking test to observe whether the hammer hardness is appropriate or not. The hammer of the string striking machine is made of 100% compressed pure wool, and the key parts (such as the rotary hammer, linkage, etc.) are made of wood imported from Australia and other countries, and Shenda and loose fabrics imported from Britain, Japan and other countries; High stability and high sensitivity (can be used normally at - 20 ℃ - 50 ℃, and can be hit 160000 times continuously in the environment with relative temperature of 15 ℃ - 35 ℃ and relative humidity of 40% - 70%); 1/250 second instantaneous chord striking; The high-quality string striking machine ensures that the "Schwarzwald" voice is beautiful, exquisite and beautiful. Create a new realm of music in exquisite stability.
The strings are made of expensive steel wires of SUZUKI (Suzuki, Japan) and ROSLAU (Leslau, Germany); The string code is made of high-quality trail wood; The tuning button makes the effective chord length of each string more accurate, ensuring the natural transition of low, medium and high tone; The chord board is made of 17 layers of wood, and the chord pin is heat treated to make the piano have excellent intonation and stability. Be perfect in details.
The factory paint shop adopts automatic paint spraying machine. The piano shell parts are arranged in sequence on the conveyor belt and slowly sprayed by wax gram or polyester
Grand piano
The fog chamber is sent to the drying chamber. A "Schwarzwald" piano shell shall be polished after 4 layers of wax coating or 8 layers of polyester coating. The painting workshop has a set of well-designed ventilation device, which greatly reduces the pollution of wax and polyester spray. The paint is a special polyester piano paint imported from Germany, with high gloss, strong hardness, strong durability, comfortable touch and green environment.
The piano keyboard adopts special technology. High quality imported white pine solid wood, through the most advanced drying, moisture-proof treatment to ensure that the keyboard in normal use does not deform, distortion durable. The white key is designed like ivory, and the black key is made of frosted surface, which makes it particularly comfortable to touch the key; Each key can obtain a uniform weight by measuring the counterweight separately, which ensures the minimum energy loss in the transmission process from fingertip to key, to gavel, to string, and creates a new space of quality in fine water.
