Abstract
Wood-type golf clubs and/or golf club heads include: (a) a golf club head base member including a face member having a ball striking face; and (b) a polymeric body member engaged with the golf club head base member, wherein the polymeric body member is formed via a rotational molding process (or other centrifugal force inducing molding process) and/or engaged with the golf club head base member via a rotational molding process (or other centrifugal force inducing molding process). The polymeric body member forms at least a portion of a crown member of the club head in some structures.
Claims2
A golf club head, comprising:
- a golf club head base member including a golf club head face member having a ball striking face engaged therewith or integrally formed therewith as a unitary one piece construction;
- and
- a polymeric body member engaged with an interior surface of the golf club head base member via a rotational molding process, wherein the polymeric body member forms at least a portion of a crown member of the golf club head, wherein the polymeric body member constitutes a shell formed against all interior surfaces of the base member to which polymeric material forming the polymeric body member is exposed during the rotational molding process.
A golf club head, comprising:
- a golf club head base member including:
- (a) a golf club head face member having a ball striking face engaged therewith of integrally formed therewith as a unitary one piece construction and (b) an aft body portion having a plurality of open cells, wherein at least some of the plurality of open cells form a crown portion of the golf club head base member;
- and
- a polymeric body member engaged with an interior surface of the golf club head base member via a rotational molding process, wherein, during the rotational molding process, the polymeric body member fills in the plurality of open cells forming the crown portion and forms at least a portion of a crown member of the golf club head, wherein the polymeric body member constitutes a shell formed against all interior surfaces of the base member to which polymeric material forming the polymeric body member is exposed during the rotational molding process.
