Abstract
PURPOSE: To obtain the titled product such as a golf ball in which cracks are difficult to be generated at a joint part by a method wherein an outer coating polymer is formed by holding pinchedly an intermediate mold in a mold cavity and thereafter, the intermediate mold is replaced by a core body and along with this, the outer polymer is mutually made into one body.
CONSTITUTION: An intermediate mold 3 having a runner 4 is installed in a mold cavity of split type outer mold 1, 2 and a material polymer is gushed out from an extruding machine 5 through a runner 4, and it is filled in each part in a cavity (g) formed with an intermediate mold 3, thus, an outer coating polymer 6 is formed in partition. And then, the intermediate mold 3 is removed and a core body 9 which is formed separately is buried and joint faces 1b, 2b of the outer molds 1, 2 are jointed and each part of the outer polymer 6 and the core body 9 are jointly made into one body to obtain the intended product.
