Management Plan "VISION 2020"

2029 will be the 100-year anniversary of Tokyo Foundry’s company establishment.
This is a major milestone since its establishment which we will take as a reason for
building the road to the next generation for both group companies.

In an ever changing business environment,
we think that it is important to continue contributing to the industry and
to the society by creating castings of extraordinary quality.
We will evolve and further reform our existing business.
At the same time we need to take new business opportunities.
With the next five-year plan "VISION 2020' we plan to strengthen our organization by 2030.
Tokyo Foundry Co., Ltd. and NAIGAI Co., Ltd. will jointly follow the new strategy,
ensuring the smooth succession for existing projects.

"VISION 2020" Theme and Main Policies

01. Persuing Extraordinary Quality

IATF 16949:2016 certification

We got certified according to the automotive industry's advanced quality management system IATF 16949:2016 (13 July 2018).

This Registration is in respect to the following scope.
NAIGAI Co., Ltd. / Tokyo Foundry Co.,Ltd.
561-8 Kamitoyooka-machi, Takasaki-shi, Gunma 370-0871 JAPAN
Manufacture of Aluminium Casting Parts for High-Pressure Fuel Injection Pump and Turbo Charngers. (Permitted Exclusions:Product Design)

Mass Production of the H-Process

The H-Process is a casting method to realize high-accuracy, low-cost. Mass production trials started in February 2015.

Production at the Plant in India

In 2013, NAIGAI and Simplex established the joint venture company
“Simplex Naigai Castings”
in Bangalore India.
Just like in Japan, the plant in India will focus on
casted aluminum parts for automotive applications.
The production lines as well as
the quality management will also be the same as in Japan.
Data, such as process temperatures of the production lines
in India can be monitored in Japan in real time,
insuring the same level of extraordinary quality as the parts made in Japan.
The construction of the plant in Bangalore is scheduled to be completed, operational from 2016.

02. Building up the “Next-Generation Casting Environment”

Introduction of New Technologies

With the expected depletion of fossil fuel for internal combustion engines in the future
we are also developing parts for high-tech automotive applications.
For this reason we are cooperating with other companies on global scale.

Introduction of Next-Generation Foundry Equipment

With the next generation of casting machines, which introduced in 2015, we will move up from monitoring process conditions to total control. This will enable us to run the process with even higher precision.

Post-Processing Automation with Robots

We are automating the de-burring and finishing processes by using robots. This is being done to eliminate mistakes, but also to address demographic challenges.


03. Promotion of New Business

Vegetable Cultivation

Our Shinto-Plant (formally a foundry) is now used as a plant, producing vegetable. We have introduced a hydroponic system for producing leafy vegetables. From 2015 on the test plant is operating. We intend to better utilizing resources, e.g. by using heat generated during casting operations.
Even in agriculturally active Gunma Prefecture, such an initiative is unique. It provides opportunities of re-employment for experienced retirees.

Solar Power Generation

On the roof of Tokyo Foundry’s Plant we have installed 200 kW of solar panels. In addition we have installed 100kW on the Shinto Factory. Our production uses much of this energy but we are also providing a big portion of this solar electricity to society. At the same time, it means bigger energy independence from the utility providers and secures reliable energy supply to our area in case of natural disaster.

04. Development of Next-Generation Craftsmen

Human Resource Development that Addresses Advanced New Technologies

At our company we experience a rapid growth of young employees.
While in the past, the foundry craftsmen “inherited” their technical skills,
it is now necessary for them to actively learn new technology and procedures.
We will continue to focus on training through a variety of programs to
insure the growth of the next generation of casting craftsman.

A Production Plant that Appeals to Female Employees

Increasing the percentage of female employees is also a target, we have set. For this purpose, we will change the traditional image of the plant and aim for a more pleasant environment.

Supporting Employment in the Region

Every year since 2010, NAIGAI has offered students of local schools the chance to gain business experience. Some of the trainees have later become full time employees. NAIGAI will continue to offer this support to the society.
