Abstract

A multi-piece molded golf ball which closely duplicates the aerodynamic characteristics of a top grade wound type golf ball. The ball comprises a dense center having a minimum specific gravity of 1.25; a molded encapsulating mass surrounding the center, wherein the material in contact with the center is further characterized as a low density resilient synthetic elastomer composition; and a patterned surface contouring of predetermined structure, contained within the outer surface of the golf ball.

Claims

1. A molded golf ball, comprising:

a) a center of substantially high density;

b) a molded encapsulating mass surrounding said center, wherein the material adjacent to said center is further characterized as a resilient synthetic elastomer composition including a density reducing filler;

c) and a patterned surface contouring of predetermined structure, contained within the outer surface of said golf ball;

d) said density of said center being greater than the density of said encapsulating mass.

2. The golf ball defined in claim 1, wherein said center is further characterized as a steel ball.

3. The golf ball defined in claim 2, wherein said encapsulating mass is further characterized as a cover made from a resilient syntactic foam composition.

4. The golf ball defined in claim 2, wherein said molded encapsulating mass is further characterized as an outer core and a cover.

5. The golf ball defined in claim 4, wherein said outer core is further characterized as being made from a resilient syntactic foam composition.
