Golf|Endo Manufacturing Co., Ltd.

Endo has gained a very good reputation as a manufacturer of forged golf club heads. Forging a product by striking the metal to temper it, makes the metal structure finer and stronger, and it is apparently these characteristics that give golf club heads a good feel on hitting the ball, and make ball control easier.

For us, a golf club is not just a tool. It is a part of a player's body, transmitting his or her intentions and strength to the ball. We have always insisted that forging is the way to make the sort of head that can do that.

For the manufacture of golf clubs, Endo has specialized in OEM manufacture. We believe that OEM manufacture is the very best way to bring the experience of our technology to greater number of golfers, pairing the strength of Endo's advanced forging technology with the strength of golf club makers' brands.

Endo receives manufacturing orders from well-known golf club brands around the world, not just from Japan. We have a product development setup that enables us to rapidly meet customer requirements, and a manufacturing setup that can handle mass production.


	Product Development Starting from the product concept, plans and specifications provided by the maker, Endo's expertise and technology are leveraged to refine the specifications for each product. Data from product specifications are analyzed in three dimensions using CAD systems, and then utilized to make the machine tools for the manufacturing process and to ensure that fine and precise products are made.
	Tooling Machine tools are made based on 3-D data from the product specifications. The shape is reproduced faithfully to the design drawings, and then goes through a series of checks and adjustments, eventually producing the tools that will be used to produce irons and metals. Endo has brought tooling work in-house, enabling rapid and detailed response to maker's requirements.
	Pressing The titanium alloy material for the metal heads is aligned with dies and press-formed. Titanium alloy is difficult to machine, but Endo has the metal machining technology and experience needed to form accurate shapes speedily at low cost, developed through years of working with materials such as stainless steel. Precision Forging In the forging process, the soft iron material for iron heads is heated and struck to form the required shape. Endo's precision forging technology that has been evolved from ordinary forging is used to manufacture forgings with good performance in terms of both dimensional tolerances and surface finish. The complex shapes of iron heads can be formed precisely by forging, combining many of Endo's technical specialties in a single process.
	Welding The welding process is where the parts of metal heads (face, crown, sole, hosel) are welded together to make up the head. Precision is required because this process determines the basic shape. Irons and metals need even more precise and bimetallic welding, that is why laser welding technology is used. Machining Center The forged products are then cut using a numerical control machining center, tidying up the surface shape. Using a machining center for this machining process ensures the manufacture of high-quality products with little product variation.
	Polishing In addition to faithfully reproducing the head surface shape in the design drawings, this process makes the surface smooth. The polishing work actually divided into four or five individual processes. Polishing is largely a manual process, with workers using their well-developed skills and experience to finish each head individually, with the whole process reminiscent of the production of craft objects.
	Plating/Painting The head surface is plated/painted to produce the final product. Painting robots are used in the painting process to prevent uneven coloring and produce an even finish. Since this is the final process, there is a particularly strict quality control setup. The result is a beautiful product with an attractive sheen.
	Inspection and Assembly The heads are fitted with shafts and grips to assemble the club and complete the manufacturing process. The finished products are then checked very carefully by the hands and eyes of inspection staff. This final inspection covers all the different aspects, including checking for defects in each of the components, and checking the overall balance.
