1．The piano uses a hard wood back column, solid back frame structure.HG150SE is still stable under great tension.
2．HG150SE is not only in line with the piano industry requirements, but also protects the product quality and stability by applying CNC five - axis machining bending.
3．The drilling work on iron plate of the HG150SE, 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 controls the quality of the piano.
4．Hailun's piano makes the assembly precision to meet industry standard requirements through the temperature control and humidity of the wood and workshops, Hailun's the unique positioning patented technology and the CNC processing technology from Japan. So that it controls fundamentally the stability of the piano. And so does HG150SE .
5．HG150SE’s keyboard is HAINSWORTH felt from the UK, which has good weatherability, so that the piano can be stable in different environments.
6．HG150SE’s spruce soundboard plays an important role in the sound quality and tone. The FFW hammer felt from Germany ensures the softness of sound quality. The ROSLAU high strings from Germany can ensure the soft tone and the good overtone of the strings while playing.
7．The ribs and other wood parts of HG150SE are selected from various woods in northeast China. Solid wood string code is conducive to transmission of sound.
8．Golden metal parts and copper pedals ensure stability and elegant appearance.
