Golf club face plates with internal cell lattices and related methods
Embodiments of golf club face plates with internal cell lattices are presented herein. Other examples and related methods are also disclosed herein.
1. A method for forming a golf club head comprising:
providing a golf club head body wherein the body comprises an opening in a front end;
printing a face plate layer by layer having a cell lattice with an inner skin, an outer skin, a midsection, and a plurality of apertures using a powdered material;
wherein in the outer skin comprises at least a portion of a strike face of the golf club head;
wherein the cell lattice comprises a plurality of cells;
wherein each of the plurality of apertures extends from a cell within the midsection of the cell lattice;
wherein each of the plurality of apertures extends through the inner skin, or through the outer skin of the face plate;
positioning the plurality of apertures to allow removal of excess powered material;
applying force, pressure, or vibrations to loosen excess powered material within the cell lattice;
applying compressed air to the plurality of apertures to remove excess powdered material;
filling in the plurality of apertures resulting in a face plate having flush inner and outer surfaces; and
coupling the face plate to the opening in the front end of the golf club head body;
wherein the plurality of apertures include at least a first aperture positioned near a center of the cell lattice and remaining apertures positioned around a perimeter of the cell lattice;
wherein applying force, pressure, or vibrations to loosen excess powered material within the cell lattice further comprises striking the face plate with a rubber mallet, applying ultrasonic vibrations, or shaking the face plate with a tumbler or shaker.
2. The method of claim 1 , wherein each of the plurality of cells further comprise cell walls having a wall thickness.
3. The method of claim 2 , wherein the wall thickness is greater near the inner skin and the outer skin than near a central region of the cell lattice.
4. The method of claim 3 , wherein a minimum wall thickness ranges from 0.005 inches to 0.2 inches.
5. The method of claim 1 , wherein each of the plurality of cells further comprise a cell width; and
wherein a maximum cell width ranges from 0.005 inches to 0.2 inches.
6. The method of claim 1 , wherein applying compressed air to the plurality of apertures further comprises first applying compressed air to the remaining apertures positioned around a perimeter of the cell lattice and then applying compressed air to the at least a first aperture positioned near a center of the cell lattice; and
repeating the application of compressed air to the perimeter and center apertures as needed to remove any excess powered material.
7. The method of claim 1 , wherein each of the plurality of apertures are spaced apart from the remaining apertures by a distance greater than or equal to two times a diameter of the plurality of apertures.
8. The method of claim 1 , wherein the powdered material is selected from a group consisting of Ti-9S, Ti-6-4, and Ti-8-1-1.
9. The method of claim 1 , wherein printing the face plate comprises using direct metal laser sintering, 3D printing, stereolithography, fused deposition, or electron beam melting to print each layer.
10. The method of claim 2 , wherein the cell walls further comprise transverse passageways between at least two adjacent cells of the plurality of cells.
11. A method for forming a golf club head comprising:
providing a golf club head body comprising an opening in a front end;
printing a face plate having a cell lattice with an inner skin, an outer skin, a midsection, and a plurality of apertures using a powdered material;
wherein in the outer skin comprises at least a portion of a strike face of the golf club head;
wherein the cell lattice comprises a plurality of cells;
wherein each of the plurality of cells further comprise cell walls;
wherein the cell walls meet at cell junctions such that two or more cell walls couple together;
wherein each of the plurality of apertures extends from a cell within the midsection of the cell lattice;
wherein each of the plurality of apertures extends through the inner skin, or through the outer skin of the face plate;
positioning the plurality of apertures to allow removal of excess powered material;
applying force, pressure, or vibrations to loosen excess powered material within the cell lattice;
applying compressed air to the plurality of apertures to remove excess powdered material;
filling in the plurality of apertures resulting in a face plate having flush inner and outer surfaces; and
coupling the face plate to the opening in the front end of the golf club head body;
wherein the cell walls further comprise transverse passageways such that each cell is open to at least one other cell;
wherein applying force, pressure, or vibrations to loosen excess powered material within the cell lattice further comprises striking the face plate with a rubber mallet, applying ultrasonic vibrations, or shaking the face plate with a tumbler or shaker.
12. The method of claim 11 , wherein the plurality of apertures include at least a first aperture positioned near a center of the cell lattice and remaining apertures positioned around a perimeter of the cell lattice.
13. The method of claim 11 , wherein each of the plurality of cells further comprise cell walls having a wall thickness.
14. The method of claim 13 , wherein the wall thickness is greater near the inner skin and the outer skin than near a central region of the cell lattice.
15. The method of claim 14 , wherein a minimum wall thickness ranges from 0.005 inches to 0.2 inches.
16. The method of claim 11 , wherein each of the plurality of cells further comprise a cell width; and
wherein a maximum cell width ranges from 0.005 inches to 0.2 inches.
