Silencing Techonology

The 4th Generation

  • Silencing latchbolt technology

    With an integrated damper, the latchbolt will release at a constant speed of 1.0s when the door closes, reducing noise by avoiding instant release of the latchbolt.

  • Silencing handle technology

    Ultra pricision rotary damper slows down the reset process of the handle, reducing noise greatly.

The 3th Generation

  • Utilize silencing latch bolt, patented pagoda shaped spring as well as a latch bolt bush with an ‘O’ shaped soundproofing Aprons, reducing sound from all components.

  • Utilize a patented ball rolling structure and high elasticity silencing material to reduce the sound of dead bolt releasing.

  • Utilize a built-in latch bolt, dead bolt and silencing bush to reduce sound of friction in between.

  • The patented strike plate is made of strong silencing material, reducing sound from latch bolt collision greatly.

  • The follower is made of strong silencing material, reducing the sound of lever handle’s activity.

  • Spindle mount is made of high elasticity silencing material, reducing the sound of lever handle’s activity.

  • PA Nylon material is added to the handle locking plate, reducing sound from friction.

  • Use one-way piano wire reset spring, lever handle will not release instantly.

The 2th Generation

  • Patented magnetic latch bolt reduces sound of closing a door greatly.

  • Latch bolt is hidden inside the casing, offering a better appearance.

  • Latch bolt automatically returns to the casing.

  • The latch bolt is made of Nd-Fe-B magnet material covered by PA66N nylon, making it more silent and abrasion resistant.

  • Utilize buffer spring and buffer cushion, reducing sound of collision.

  • Use adjustable striking plate, minimizing installation errors.

  • Patented magnetic latch bolt reduces sound of closing a door greatly.

  • Latch bolt automatically returns to the casing.

  • Latch bolt is made of PA66 nylon, making it more more quiet and abrasion resistant.

  • Swing structured latch bolt minimizes the friction in its release.

  • A heterotypic diameter compassion spring allows the lever handle spin at constant speed.

  • Use adjustable striking plate, minimizing installation errors.

The 1th Generation

  • The patented strike plate is made of strong silencing material, reducing sound from latch bolt collision greatly.

  • Patented pinch greatly buffers the force from the latch bolt.

  • Inside the latch bolt is made of high impact silencing material greatly reduces sound from collision.

  • Latch bolt utilizes a sphere design, minimizing collision contact surface.

  • The latch bolt and slider is fixed, zero friction.

  • High-impact buffer spring is added.

  • Utilize high-impact silencing material, reducing sound of friction.

  • The slider utilizes a patented sphere design, integrated with the lock casing perfectly, reducing noise greatly.

  • High-impact silencing material is added to the follower, no noise will be caused when the lock closing.

  • The patented strike plate is made of strong silencing material, reducing sound from latch bolt collision greatly.

  • Patented pinch design greatly buffers the force caused by latch bolt closing.

  • High-impact silencing bush is added to the latch bolt and dead bolt, reducing sound of friction in between.

  • High-impact silencing material is added to the latch bolt, greatly reducing sound of friction.

  • Latch bolt utilizes a sphere design, minimizing collision contact surface.

  • A latch bolt bush with an ‘O’ shaped soundproofing Aprons, reducing sound from all collision.

  • The latch vane uses high-impact silencing material instead of metal, reducing noise from friction.

  • Reset spring connects to high-impact silencing vane, reducing noise from vibration.

  • The follower controller is a pick instead of a spring, greatly reducing noise from collision.
