GREETING
Since our establishment in 1947, we have always pursued the potential of new technologies and
continued to grow. In addition to the traditional Tokoname and Arimatsu plants, we constructed
the Toyoake plant in 2023, and have established an integrated production system that includes
everything from product development to tooling design and fabrication, pressing, welding,
machining, assembly, and surface treatment, mainly for automotive applications.
In our technical department, with the introduction of state-of-the-art equipment, we have been
able to produce unique, high-functioning stamping tooling and achieve complex, high-precision
press processing. In the production department, we have built an efficient production system
through the use of our own developed press machines and automated equipment, and we are actively
engaging in the production for next-generation vehicles such as EVs, especially in recent years.
As the external and economic environments change rapidly, adapting flexibly remains a
significant management challenge, but responding to DX is also essential in the upcoming digital
society. As one part of realizing this, we have developed and are utilizing the cloud system
called IoTGO, which allows us to understand the operation status of facilities in real time and
improve productivity, in cooperation with our affiliated company, MicroLink Inc.
In performing daily operations, including technological development, it is essential not only to
enhance knowledge and skills but also to foster an organic functioning of the organization based
on the spirit of harmony, trust, and communication, so that all employees can fully demonstrate
their abilities. To this end, we are focusing on effective human resource development and
creating a safe and rewarding workplace.
We will continue to leverage our strengths to create value that pleases our customers, strive
for the prosperity of the company and the happiness of our employees, and aim to become a
company that contributes to the local community while pursuing the dream of becoming a
100-year-old company.
We look forward to your continued warm support.
Motto: Happiness, Service, Prosperity
Management Philosophy: Polish skills,
Nurture harmony, Realize dreams.

WHY CHOOSE KUNO KINZOKU INDUSTORY
Precision within ±1/100 mm
Technical capabilities for complex, high-precision presswork
For presswork makers, dies are the most important piece of know-how, and the technical capabilities of presses are mostly determined by die precision. At our company, more than 90% of dies are fabricated in-house, taking advantage of our expert die-making techniques and extensive equipment line-up. We handle everything in-house from the design to manufacturing and maintenance, and we have built advanced technologies in the fields of die design, die parts processing, and trial adjustment, which are the key to high-precision dies.
-
Die Design Technology
- It is no exaggeration to say that 80% of die making is determined by design. We make accurate blueprints with consideration given to all possible processing conditions, such as the shaping of the product, the specifications of the production equipment, the function of each processing step, a simple and high-precision die structure, and the ease of assembly, adjustment, and repair. For high-tensile steel that is easily affected by various processing conditions, it is difficult to make good products with just experience and die structure; for reliable designs, we employ simulation technology to create the optimal expected shape of die parts.
-
Die Part Processing Technology
- High-precision equipment is indispensable to the making of high-precision die parts. We have carefully selected all our equipment, including four jig borers controlled to with 1/10,000 mm and wire-cut electrical discharge machines from Yasda Precision Tools K.K. Combining these with the most advanced tooling, we are able to shorten the processing time as well as increase the precision of processing. We also design and manufacture our own jigs, which are necessary for the “set-up” that determines machining precision.
-
Trial Adjustment
- Trial adjustment is a technique for the final adjustment of an assembled die to ensure that the pressed parts are made according to the design. Swift and accurate adjustments require the sense of skilled workers; in particular, with a complex and high-precision pressing that involves many molding processes, the slightest adjustment can lead to significant differences in the end result. From our foundation, we have continued to build upon the experience of die workers who exert high skill when making adjustments.
Integration of craftsmanship and automation through the use of ICT
Since the development of FA robots in the 1980s, we have been putting effort into the use of ICT. Using a combination of our own servers, IoT, and cloud computing, we have introduced a dedicated in-house system for production management, die management, quality control, management of EDI suppliers, all the way to automated warehouse management. We are also moving forward with the automation of our expertise with ICT for the improvement of production processes using mobile devices and the systemization of our craftsmen’s intuition and skill. This has enabled the creation of an environment in which staff can concentrate on coming up with work ideas and strengthening their technical capabilities.
Diverse employee education, including technical certification and training
Our company has a history of more than 70 years with advanced technology as our competitive edge. Since our founding, we have placed the utmost importance on the development of outstanding staff to support our technical capabilities, and have continued to actively foster development of skills through various education and training programs. We also exert effort in creating a climate that encourages proactive technical improvement and the improvement of productivity at worksites through technical certifications that motivate staff to improve their skills and through club activities that provide opportunities for self- and mutual development.

SERVICE
We provide a one-stop service for high-precision, complex presswork.
We are a metalworking manufacturer that provides a full range of services manufacturing pressed
parts for automobiles and other equipment, from process development, product design, die design
and creation, and pressing, through to secondary processing such as machining, welding, and heat
treatment. With a combination of wide-ranging underlying technologies, expert die-making
techniques accumulated since the company’s founding, and a variety of equipment developed
in-house, we are able to provide difficult highly complex high-precision presswork. We support
production of the most advanced parts, a field that is progressing rapidly in functionality,
such as through the use of high-tensile materials.
With our integrated system that handles all pre- and post-processing of presswork, it is
possible to manufacture products with consideration in the development stage given to processes
after pressing. By creating manufacturing drawings in consideration of post-processes, which are
not shown in the product blueprints, we can prevent problems that may arise during mass
production, and also improve precision with the combination of processes. Even if you only
require product blueprints, we can provide the shape and precision you need quickly and
reliably.
