The use of positioning technology in the manufacturing process, including code string soundboard with a back frame, the back frame with iron plate, the back frame with the shell, makes the piano exquisitely assembled.
component detail control
We use digital management in the manufacturing process of piano. The iron milling of the string, the formation of the string pillow button hole and the peg hole, positioning hole on back frame and milling soundboard frame and rib groove are made by CNC numerical control machining to make the details of the piano parts are under control.
Automatic friction of the string machine weakens the string stress, and ensures a longer and more stable tone.
It is made of FFW felt imported from Germany, which makes the elastic and hardness of the whole string hammer evenly distributed, and has good durability and weather resistance.
Hammers with core mat make the treble portamento more long. The hard core of the mallet wood is made of hard peach kernel wood, which has good hardness, toughness and internal stress.
The transmission ratio data of action is rigorous and strict.
The hard aluminum alloy is used to make the main parts such as the main gear, the back gear, the adjusting beam and so on. The structure is firm and not easy to deform. CNC automatic drilling new technology controls the dimensions of the various parts of the action machine scale.
Multilayer of solid wood embedded with aluminium alloy prevents the piano from deformation due to climate or other reasons.
European plug-in soft sound system
It is solid and easy to assemble and disassemble. It helps to keep the piano steady while playing and at the same time dampens noise.
It adopts unequal thickness and width of the soundboard structure.
Wide ranging soundboard expands vibration area and increases the vibration area in the treble area.
Based on the calculated unequal-thickness soundboard and arc design, different frequencies of the string vibrate resonate with the corresponding regions of the soundboard when the string vibrates, and the resonant effect of the soundboard and the vibrating waves of different frequencies is exerted.
In order to maintain a suitable torque, high pressure multilayer pin block is made of thickened veneers which is not less than 32 millimeters. It adopts European technology, hard maple, strong adhesive, uniform density. Stainless steel pegs and threading for the process design set precise layout, reasonable expansion pin spacing, uniform torque, to improve the stability of intonation.
The piano keyboard is HAINSWORTH felt from the UK, with same key depth, making the piano stable in different environments.
Its structure is exquisite and novel, and it is easy to operate.
descent control device
The humanized design can protect players’ skillful hands.
ebony solid wood keyboard
The ebony keyboard is not only comfortable, beautiful and natural, but also changes the dynamic and static load of the piano by means of built-in counterweight adjustment.
screws and washers
Fastening screw and cylinder washer that use gold and silver suits on the iron plate is finely processed with elegant and pleasant appearance.
string pillow twist
The bass area of the piano adopts the design of the string pillow twist, same as the chord structure of the triangle bass. The double chord set coordinates the effective chord length of the same set of strings, and the bearing force is even, and the vibration performance is stable.
Powerful European rectangle iron plate (the patent number: ZL200720073606.3) is rectangular frame structure. The chord of the sound source is firm and stable, and the hole layout is reasonable.
Pedals made of brushed stainless steel and some metal parts made of high-gloss stainless steel have better weatherability.
