    • A golf club head includes a face insert that comprises an insert core made of a relatively hard (high durometer) durable polymer material that is surrounded on at least its rear and side surfaces by an insert shell made of a second softer (lower durometer) polymer material. The insert shell allows the harder insert core to “float” within a cavity in the club head while being surrounded on all sides by the softer insert shell. This arrangement of the insert core and the insert shell thus provides the advantages of a durable impact surface for desirable acoustic feedback while at the same time resulting in desirable feel due to the softer insert shell surrounding the harder insert core.
    • 一种高尔夫球杆头包括一个面插入件,其包括由相对硬(高硬度)耐久的聚合物材料制成的插入芯,其通过由第二软(低硬度)聚合物制成的插入壳至少在其后表面和侧表面上包围 材料。 插入外壳允许较硬的插入芯在球杆头的空腔内“漂浮”,同时通过较软的插入外壳在所有侧面上被包围。 因此,插入芯和插入壳的这种布置提供了耐用的冲击表面的优点,用于期望的声反馈,同时由于围绕较硬插入芯的较软的插入壳而导致期望的感觉。
