01Product Development

Based on the product concept developed by the customer, we leverage our design know-how and production technology to that plan and refine the specifications for each product with the customer. We work on product development to realize the concept using advanced CAD modeling technology and simulation technology.

02Master Model

Golf club heads are CAD-modeled, and a prototype master model for each is then produced. We work on manufacturing a product with the belief that human senses should be taken into account, such as the feel and sound of hitting the ball.


Tooling is made in-house based on 3D data of a master model, and tooling for irons are produced through precise processing. We have brought tooling work in-house, which is the heart and soul of manufacturing to enable rapid and detailed responses to the customer’s requirements.

04Precision Forging

In the forging process where the raw material is heated and struck to form a required shape, we manufacture forgings through our accumulated “precision forging technology.” Refined grain structure and oriented grain flow produced in the forgings significantly improve the physical properties of the metal such as strength and flexibility, and also achieve accurate dimension and smoother forged surface.

05MC and Welding

The forged products are cut using a numerical control machining center and the shape of the mating surfaces is formed. By using a 3-D welding robot, automated welding can be done even on a 3-D curved surface like a golf club head precisely.


Our polishing process involves a combination of automated polishing and hand polishing by our highly skilled workers. This enables us to create uniform and smooth surface finishes even when the shapes are complicated, while still ensuring that the head surface shape is reproduced in accordance with the master model.

07Plating and Painting

The golf club head surface is plated and painted using an automated plating line and sophisticated painting technology. The result is a finished golf club head that is beautiful with an attractive bright sheen.
