We have received high evaluations from our business partners in terms of quality and cost.
At Field Core, we shape materials from sheets through forging, and after machining the end faces, we perform processes such as drilling and protrusion. This is a technology that Ninomiyah Co., Ltd. excels at. For pistons, high quality and precision are required as they are critical safety components directly related to the driver's life. For hubs, after cold forging, we carry out drilling and trimming processes using a press machine. In the case of forged products made from bars, we have challenged various shapes through transactions with dozens of customers. If you have products that other companies cannot process and have declined, please consult Ninomiyah Co., Ltd. once. For more details, please contact us or refer to our catalog.

Company information
Ninomiy Co., Ltd. was founded in 1961 and initially operated as a press processing company. From 1981, it gradually shifted towards cold forging processing. Being a latecomer, it started with basic tasks and gradually improved its technical capabilities, increased its equipment, and actively challenged advanced technologies. In cold forging from plates, leveraging its know-how in press processing, the company has received high evaluations from its clients in terms of quality and cost. One of the achievements of this effort was receiving the "Nakagawa Takio Technical Award" from Gunma Prefecture in 2005. Additionally, the company expanded into Guangzhou, Guangdong Province, China, where "Guangzhou Ninomiy (Cold Forging) Auto Parts Co., Ltd." began mass production in 2006. As one of the few Japanese cold forging manufacturers, it has been steadily increasing orders, primarily from Japanese automotive parts manufacturers. Moving forward, the company aims to enhance its technical capabilities and quality, making "technology development that secures orders" the unwavering foundation of its operations, and to continuously establish technologies that can only be achieved in-house.
