摘要： An iron golf club is one made of metal material, which is manufactured integrally through press working and gives dedication to improvement of golf club design. The head (1) has a concave portion (4) surrounded by a convex portion (6) in the backside portion (3) behind the face portion (2). Treatment for making a mirror surface is applied to the bottom portion (5) of this concave portion through press working with a fixed die (11) having a surface roughness finer than the mirror surface for which treatment for making a mirror surface is to be performed and a movable die (10). Press working of this bottom portion can be also performed through treatment for making a mirror surface with a liner member (17).
摘要翻译：铁高尔夫球杆是由金属材料制成的，通过压力加工一体制成，并致力于提高高尔夫球杆的设计。头部（1）具有由面部（2）后面的背面部（3）中的凸部（6）包围的凹部（4）。通过对具有比要进行镜面处理的镜面精细度更高的表面粗糙度的固定模具（11）进行加压加工，对该凹部的底部（5）进行加工处理和可动模具（10）。该底部的压制加工也可以通过用衬垫构件（17）制造镜面的处理来进行。
