Abstract
A method and apparatus for manufacturing a preform component for a golf club head composed of a plurality of plies of pre-preg material is disclosed herein. The preform component is preferably a face component, a crown component or a sole component, composed of a plurality of plies of pre-preg material. The apparatus preferably has a plunger head attached to a pneumatic cylinder for compressing the plies of pre-preg sheets within a mold cavity configured to define a preform component.
Claims1
A method for forming a sole component for a golf club head, the sole component composed of plies of pre-preg sheets, the method comprising:
- placing a first plurality of plies of pre-preg sheets in a mold cavity of a mold, the mold cavity configured to define the sole component for the golf club head;
- lowering a first plunger head along a longitudinal axis toward the mold cavity, the first plunger head configured to compress the first plurality of plies of pre-preg sheets within the mold cavity of the mold, the plunger head composed of an elastomeric material having a durometer of 25 Shore A to 85 Shore A;
- compressing the first plurality of plies of pre-preg sheets with the first plunger head within the mold cavity of the mold;
- replacing the first plunger head with a second plunger head, the second plunger head smaller in volume than the first plunger head;
- placing a second plurality of plies of pre-preg sheets in the mold cavity over the compressed first plurality of plies of pre preg sheets;
- lowering the second plunger head along a longitudinal axis toward the mold cavity, the second plunger head configured to compress the second plurality of plies of pre-preg sheets within the mold cavity of the mold;
- compressing the second plurality of plies of pre-preg sheets with the second plunger head to the compressed first plurality of plies of pre-preg sheets to form the sole component for the golf club head;
- removing the sole component of the golf club head from the mold cavity.
