W152

width: 151cm     length: 152cm      height: 102cm
 
1．It is not only in line with the piano industry requirements, but also protects the product quality and stability by applying CNC five - axis machine.
2．The drilling work on the W152 piano iron plate, the milling of the string reinforcement and the connection between the components of the sound source are completed by the high-tech CNC control equipment. It controls the manufacturing accuracy and the quality of the piano.
3．During the making process of Wendl & Lung W152, Hailun ensures the assembly precision to meet industry standard requirements through the temperature and humidity control in the workshops, Hailun's unique positioning patented technology, and the CNC processing technology are from Japan. So that it fundamentally stabilizes the piano.
4．Hailun W152 piano keyboard felt is HAINSWORTH from the UK, which has good weather ability, so that the piano can be stable in different environments.
5． The spruce soundboard is a good medium for mellow tone and sound transmission. It adopts unequal thick and width of the soundboard structure, enlarges the vibration area of the soundboard, and plays the resonance effect between the sound board and the vibration wave of the string of different frequencies.
6.  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 longer. The hard core of the mallet wood is made of hard peach kernel wood, which has good hardness, toughness and internal stress.
7．The beam and inclined frame of W152 dorsal column remained stable under tension of the piano strings . Hailun piano's ribs and other wooden parts are selected from various woods in cold zone. Solid wood string code is conducive to transmission of sound.
8. W152 piano tuning peg uses chamfer threading technology so that the tone is smoothly without noise. The string axis board of Hailun HL 125-a is made of 18 layers of maple. And it is stable and firm.
9. The ROSLAU high quality strings from Germany used on W152 can ensure the soft tone and the good overtone of the strings while playing.
Automatic friction of the string machine weakens the string stress, and ensures a longer and more stable tone.
10. 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. Ebony can absorb the sweat during playing and prevent slipping.
11. Based on the principle of effective chord length and long - frequency harmonic resonance, it adopts the non-equidistant double chord support string long structure design to make the sound more expressive.
12. W152 is equipped with a keycap descent control device to protect the player's hands.
13.W152 piano is equipped with golden metal parts and copper pedals. It has stable performance and elegant appearance.
