forging

We have built a solid reputation for manufacturing parts under high loads that require high precision such as connecting rods, which are engine parts, and transmission gears for automobiles as well as two-wheeled vehicles and agricultural machinery. We are also responsible for manufacturing critical parts directly related to social infrastructures, such as turbine blades and vibration control dampers for construction machinery, railroads, and power plants.

We can handle difficult-to-process materials such as titanium, high-strength alloys, aluminum, and stainless steel, and help our customers to design parts without compromising design flexibility. For titanium products, we have a track record of forging golf drivers and demonstrate our technical skills in manufacturing parts that require high precision and high strength. We meet our customers’ needs from high-mix small-batch production to mass production, such as reducing product weight and enhancing strength.

Endo Manufacturing is highly regarded in the forging field for our total focus on the customer. We work to understand your design intent and then propose the most appropriate processing method and materials. We develop products according to the needs of our customers and achieve high-quality manufacturing in all processes from production to delivery. We can handle small-batch and high-mix production, and can also flexibly handle overseas projects.

We have established a forging plant and manufacturing base in Thailand, where automobile industry manufacturers from all over the world are concentrated. ENDO FORGING’s quality control system, which is based on international standards such as ISO 9001* and IATF 16949*, has convinced Japanese automobile manufacturers as well as U.S. and European manufacturers to choose our products. This allows us to ensure a supply system in line with industrial globalization. We can also serve as a supplier for overseas manufacturing.

*We have obtained ISO 9001 and IATF 16949 certification (ENDO FORGING)

We manage the entire process from mold design to mold fabrication and hot forging, all in-house. This allows the design intent to be shared accurately in the early stages of product launch, even with the manufacturing site. This close cooperation between design and manufacturing significantly shortens the trial-and-error process and greatly improves the precision and repeatability of the final product.

We handle requests for new parts or specification changes immediately in-house, covering everything from initial mold design to adjustment and refabrication. This is why we are so highly trusted by our customers. Our approach overturns the conventional standard of waiting for weeks between prototyping and mass production, and drastically shortens lead time when launching a product. We help you to bring products to market quicker and streamline development costs.
It normally takes between two to three months from order placement to delivery.

In February 2025, we acquired Nichia Forging Co., Ltd. (Tomioka, Gunma Prefecture) as a wholly owned subsidiary. We make full use of a 16-ton air stamp hammer, one of the largest in the industry, to provide large forgings such as power plant turbine parts, construction machinery parts, and railroad parts. We continue to update our facilities to meet the needs of our customers. For example, we have among the largest number of electric upsetting machines in Japan.
