Abstract
A connecting method for the wax patterns of the golf club head includes the steps of: prefabricating a first wax pattern and a second wax pattern, the first wax pattern providing with an engaging portion for engaging with the second wax pattern; employing a temperature difference to generate a manufacturing volume tolerance between the first wax pattern and the second wax pattern; combining the engaging portion of the first wax pattern with the second wax pattern; and cooling the first wax pattern to shrink the engaging portion so as to fittingly combine the first wax pattern with the second wax pattern.
