The MECHANIKA is a fourth-class reed. The reed plates are produced with precise cutting technology to achieve a smooth, clean surface. Pressing is done from an AI profile with a minimal hardness of 85 HB. The tongue gaps are pressed with an accuracy of +/- 0.01 mm. The plate surface is planed, mechanically cleaned, and deburred.

The tongues are ground from reed steel with a strength of 2 000 N/mm² and pressed from planchets with a width of 240 mm. The riveting of the reed plates is completed by machine with the following maintenance of a maximal air gap at the tip of 0.13 mm. A characteristic feature for the Mechanika class is a narrower tongue of 6.6 mm.

The reeds are made of Al alloy with hardness 95 HB. The channels are pressed by a precision cutting system. The surface of the reed is planned or ground. The reeds are made of Swedish voice steel with a strength of 1 950 N/mm² with a tolerance of T3, ground to an accuracy of -40 cents of the basic tone with a head width at the rivet of 6-8 mm, with corrosion protection. The reeds are machine riveted with an air gap of 0.06 mm on each side of the tongue and machine tuned to an accuracy of +/- 5 cents.
