BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates to a golf club head having a cushion channel and a manufacturing method therefor. Particularly, the present invention relates to the cushion channel formed between a through hole of a main body of the golf club head and a prepared carbon fiber plate. More particularly, the present invention relates to an elastic colored filler filled in the cushion channel to prevent from the occurrence of wrinkles or deformation on peripheries of the through holes and the carbon fiber plates.
2. Description of the Related Art
A conventional golf club head mainly includes a main body and a striking plate attached thereto, all of which are made of metal or alloy. The main body is integrally formed as a one-piece single member by casting. Alternatively, the main body is constructed from several members consisting of a crown plate, a sole plate and a side plate by welding. As to the striking plate, which is attached to a front surface of the main body by incorporating, welding or embedding. To meet various requirements, manufactures may change the configuration and the structural connection of the main body and the striking plate to lower its center of gravity and also to reduce its total weight. Since the main body is generally made of metal, the center of gravity and the total weight of the main body cannot be effectively and specifically adjusted.
Another conventional golf club head mainly includes a metal main body formed with an opening at its top portion and regarded as a filling portion. Plurality of prepared carbon-fiber fabrics are piled up to form a carbon fiber plate, and the carbon fiber plate is used to attach to the opening of the main body in place for sealing it. The prepared carbon-fiber fabrics have plasticity before heating and hardening it. Firstly, the main body is placed in a die assembly and an air-inflating bag is used to support the prepared carbon-fiber fabrics on the main body so that the main body can be formed with a carbon-fiber portion. Light material of the carbon-fiber portion may cause reduction of weight and thus the center of gravity and the total weight of the main body can be specifically adjusted. By manufacturing such large-size carbon-fiber portion, it has sophisticated the manufacture processes of the prepared carbon-fiber fabrics and prolonged the manufacture time. In manufacture operation of the carbon-fiber plate, it reduces the product quality due to irregular and uncontrollable deformation of the prepared carbon-fiber fabrics in nature. Moreover, a large area of the prepared carbon-fiber fabrics may weaken the entire structural strength of the main body, and it may further make a lower striking sound instead of a sharp striking sound naturally made by a metal golf club head.
Another conventional golf club head and the manufacturing method therefor are shown as
