Abstract
Method for reducing the weight of molded golf club heads without changing their shape. Cavities of appropriate length and volume are created in the molded heads, extending from the rear face towards the front face thereof. Despite the cavities, the heads achieve a good restitution of energy, a good mass distribution, a low level of vibrations, and a good sound.
