HS-CF (Phụ Kiện Mâm Đĩa Than)

CFRP (Carbon Fiber Reinforced Plastic)

The most essential thing for headshell is high structural rigidity yetlightweight and capability to attenuate unnecessary vibration. We selected CFRP,Carbon Fiber Reinforced Plastic, for HS-CF as the best material which satisfiessuch requirements.

Its 4mm thick shell part is composed of seventeenlayers of prepreg material (carbon fiber). At the planning phase, we employedsingle directional alignment with an exception of the center layer in order togain vibration damping property maximum. By the application of Epoxy resin as amatrix material, its mechanical strength property remains unchangedsemipermanently. It is brought to completion by angle type casting to avoidadhesive joints and cutting operation by CNC machining.

The seventeenlayers prepreg material is made from T700, highly rigid carbon fiber,manufactured by TORAY and “1K cloth” is employed as its surface material and ismade from T300 carbon fiber which is also manufactured by TORAY.

5N Silver lead wires （HSR-AG）

0.2mm 5N pure silver wires are manufactured byadvanced manufacturing processes such as continuous casting process inhigh-frequency electric furnace, cold rolling process, annealing operation anddrawing process. They are stranded in seven lines to insure enoughcross-sectional area and minimize its conductor resistance.

Theemployment of double layered silk covering insulator realizes clean signaltransmission without static electrical charge. Although resinic materials suchas PVC or Teflon are easy to be negatively charged, in contrast, silk haselectric resistivity to static charge and excellent electrical characteristic.Moreover, the glass fiber sleeve also has high insulation property andresistance to electrical static charge.

The rhodium plated lead tip ismade of phosphor bronze and enhances degree of adhesion with contactpins.
