German and Japanese piano manufacturing experts are perennially retained as the technical advisers.

Senior engineers GAO JUN WU and MA WEI who have more than forty years experience in piano manufacturing are highly invited to join in the company.

Referring to the Europe manufacturing standards of piano, the company has completely introduced Germany manufacturing technology, and combined the most advanced Japanese technology.

On the base of absorbing and innovating, we have built up a perfect DUKE piano technology system. Strict technology standard ensures the DUKE piano of transcendental tone.

80 percent of the major raw materials of the DUKE piano comes from Germany and Japan.

Alloys string adopt Germany famous brand Ruthle, while ingenious string-hitting element adopts Germany famous brand Renault. Australia log, England felt, Japanese hammer and Italian paint are also its features.

Careful material selection ensures the DUKE piano of dignity and outstanding quality.

Every technical worker has been strictly trained for more than 900 hours for his position. Only he has passed the test, he will be qualified. More than 90 percent of mechanical elements are made of natural wood. Few plastic and metal elements cause DUKE piano having a high sensitivity. The pear shape hammer designed through computer and convex shoulder bring DUKE piano the music characteristic full of vitality. Good quality spruce wood used for manufacturing wall bars bridges are firstly completely dried under the natural condition for two years, then careful selections of nine procedures are followed. The selected wood must be treated with computer-controlled dryness. In this way, more than90 percent of the products won’t deform or split in any atrocious weather or natural environment. Neat keyboard are compounded with well-selected three-layer wood that has been naturally and artificially dried. Wood texture is carefully selected. Every keyboard has been tested for weight and balance to enable piano keys to keep high sensitivity and comfortable touching sense under the condition of overlarge bounce and long touch wear.

Slap-up solid wood acoustic board in the phonation system development by domestic and overseas expert fully shows such advantages of DUKE piano as sweet and smooth of timbre, width and profundity of diapason, nature and purity of tone. Torsional moment test is carried for every imported string axis board. Under the condition of common use, the swing will hold the line for 365 days after the following lofty adjustment by tuner. Through such a long time as 15000 hours of drilling that includes technology and art, a piano with perfect tone is completed.
