an improved golf ball injection process and mold uses electrically driven part ejection mechanisms as actuators to control retractable core pins that support a preformed core in a spherical mold cavity . the electrically driven , actuator controlled pins can be precisely and independently controlled in both the upper and lower mold segments to achieve the desired positioning and velocities in the vertical axis , with varying degrees of pinch to hold the spherical core inserts . the forward and retract position of the core pins , as well as the ability to profile pin velocities , can be easily adjusted by the molding machine &# 39 ; s computer process controller without changing mechanical stops internal to the mold . the sequence timing can be set so that the core insert can be suspended and encapsulated by plastic with varying timing , allowing for the core insert to be shifted during the molding process .
