In our dedicated pursuit of exceptional quality, we strive not only to satisfy the specifications and designs required by the customer, but also focus on total cost and quality even after the product is delivered and introduced in the customer's production processes.
We work constantly with hundreds of grades of steel and have developed our own material standards for each. In terms of chemical composition, we set a far narrower range than the composition range required by the customer and implement conditions for heat treating to ensure our castings deliver the best performance.
During machining, distorsions or deformations may occur due to a casting's size, shape, or material properties. When necessary, we intentionally elect to manually machine our castings in place of using CNC machines to guarantee top quality. This eliminates variation between our castings and assures the customer a smooth production process after delivery, providing addtional cost benefits.
Together, this comprises the quality we pursue in our effort to achieve the best total cost and quality.

We continuously strive to improve customer satisfaction by providing unsurpassed product quality, delivery times, and company services.
We recognize that human and corporate activities significantly impact the environment and actively engage in environmental conservation efforts so as to leave behind a better and more vibrant planet for the coming generations.
With the spirit of "Challenging the world with our technology," we at NIDAK have made it our company policy to meet each and every customer demand for quality. On July 23, 1974, our founder Yukiharu Nishi, together with 37 colleagues, founded NIDAK as a collection of technical experts at Japan's capital of casting in Kawaguchi, Saitama.
In 1985, we established NIDAK USA to pioneer our entry into the American market, with Yoshiharu Nishi as the president. In 1997, NIDAK USA was closed in order to adopt a business-trip based approach to sales, following the shift of our American customers and business partners from the USA to Europe.
Initially, our production operations centered on four factories within Kawaguchi City. However, following the introduction of new governmental regulations, further expansion here was deemed impractical. As part of a new era of activity within the company, we constructed and shifted all operations to a new factory in Takahagi, Ibaraki, which was known for having ground well suited to supporting centrifugal casting operations.
Accompanying the appointment of a new president, NIDAK began actively expanding and developing sales channels in Southeast Asia, in addition to its American and European operations.
To address the growing number of orders and the increased complexity and sophistication of our customers' requirements, we constructed our 2nd Takahagi Factory and expanded our departments for machining, welding assembly, and inspection.
In 2013, we established a liaison office in Korea in order to further explore the Korean market.
Accompanying our continued expansion in the European and Southeast Asian Markets, our next challenge is to re-develop our market share in the USA.
Building on the legacy we have developed since our founding, we will continue our efforts to become a leading global company in our industry.
