How the Blüthner Crystal Edition is made
The manufacturing starts with the heating and molding of the acrylic for both the inner and the outer rim. Once the acrylic is cooled to room temperature, the supporting beams are assembled and glued inside the inner rim. The soundboard and cast iron frame are then fitted to the inner rim, which will support both the soundboard and the frame: the basic structure of a grand piano. Blüthner’s 36 layer pin block is placed beneath the front of the frame where holes for tuning pins are drilled and installed. The frame provides the necessary strength to anchor the strings under tension. Nose bolts and perimeter bolts anchor the plate to the braces.
The piano is then strung using Blüthner’s patented Aliquot stringing method. Keys, hammers and piano action are then put together as a complete playing mechanism, with the keybed, and placed beneath the strings. The final assembly of all parts is completed and the piano is polished. Each Blüthner piano undergoes an exhaustive quality inspection by Blüthner’s engineers before regulation and fine-tuning. Once the piano arrives in the showroom a final inspection is made prior to delivery. Blüthner guarantees you production quality and product authenticity.
