Method for the production of a hollow golf ball

摘要

The present invention provides a method for the production of a hollow golf ball, which has a perfect spherical hollow portion, excellent durability and a good shot feel at the time of hitting, without adversely affecting its rebound performance. The present invention provides a method for producing a hollow golf ball comprising a hollow core (5) comprising a hollow center (2) having a hollow portion (1) and, optionally, at least one intermediate core layer (3) formed on the hollow center (2), and a cover (4) formed on the hollow core (5), wherein the method of producing the hollow center (2) comprises the steps of: (i) preparing a rubber composition for the hollow center; (ii) forming a bowl-shaped half-shell from the rubber composition for the hollow center and vulcanizing only the inside of the half-shell; and (iii) bonding two of the half-shells to form a complete sphere body which is then vulcanized to obtain the hollow center (2).
