The following are Volvik’s patent and technology.

Volvik’s Special Dual Core


Solid Inner Core, Soft Outer Layer

  • The dual core optimizes distance by transferring the power from the more solid inner core to the softer outer layer instead of transferring inertia from a soft inner core to a solid outer layer like the competition. The outer layer also reduces excess driver spin, increasing the *moment of inertia and centrifugal force, leading to more distance and more roll.


Lower weight on the Inner Core,
Increased weight on the Outer Layer

  • It is a patented technology that increases the moment of inertia by making the specific gravity of the core outward. High moment of inertia maintains the spin for a longer period during the ball flight, which creates lift generation to improve distance and also accurate control performance.


What is moment of inertia?

  • Moment of inertia is the mass property of a rigid body that determines the torque needed for a desired angular acceleration about an axis of rotation. Moment of inertia depends on the shape of the body and may be different around different axes of rotation.
    It shows the magnitude of the property of a rotating object that rotates around the axis center. Given that no external force is applied, the angular velocity becomes smaller as the moment of inertia becomes larger.

Core patent containing Bismuth metal to increase rebound resilience

  • The outer core of the golf ball that contributes a great source of power, Bismuth, is compressed in a high temperature heating treatment. Unlike normal metal, Bismuth expands 3-3.5% in volume, leading to greater energy transfer.

Zirconium Compound Cover for a longer lasting ball

  • Zirconium is the base material for ceramic and improves durability of a golf ball cover without sacrificing spin control. Volvik combines zirconium metal in the outer cover to provide exceptional spin control and durability, while the patented elastic inner cover provides an excellent putting feel and optimal spin rates.

Dimple Design according to various spherical structure

Radially Concave Dimple Patent


What are radially concave dimples?

  • It is a dimple design where radial indentations formed at regular intervals where it has the same center as the center of each circular dimple along the edge of each dimple.


Key Features

  • The circular dimples and the radially concave dimples inside increases the flight time enabling high lift, improving straightness by constant air resistance and makes traveling amazing distances possible.
