Corporate Profile

“Giving shape to 'happiness' through manufacturing”
In 1959, at the beginning of the high economic growth period, Fuji Springs Manufacturing was founded asa small spring manufacturing company with only five employees.
We have been working hard to satisfy our customers and create products to fit the needs of ourcustomers. We believe in constant effort and continuous improvement as being our very spirit of challengethat we have inherited from the beginning of our business to the present day. In order to overcome thegeographical disadvantage of having few partner companies around us to explore new business
opportunities, we have been working on in-house production of presses and the necessary molds and dies,
as well as design and development of plating and assembly machines.

As a result, we have been able to establish relationships with major consumer electronics and heavy
electrical appliance manufacturers. In the battery business, we have shifted our focus from cell phones toin-vehicle batteries, and have expanded into the automotive business, including airbag components.
These experiences have led us to our current company, Fuji Spring Co., Ltd. which can provide one-stopservices such as technical proposals, prototyping, and mass production from the development stage. We
can provide customers with solutions that no other company can offer.

While we will continue to carry on the beliefs that we had at the time of our founding, we are also in an
era of dizzying change. There are many things that we must change, such as responding flexibly to thechanging needs of society and globalization to support local production for local consumption.

We want to value both "things that must not be changed" and "things that should be changed.”
These thoughts are expressed in our catchphrase, "Giving shape to 'happiness' through manufacturing.

Technological Capacity
ProposalContribute to customers to maximize value
through VA/VE proposals[Example] Reducing material costs for rectangular lithium-ion battery cases
Rectangular lithium-ion battery cases require a certain thickness
in part A in the figure as the sealing welding part. When this caseis made by drawing, the thickness of the plate is generally almost
the same from the bottom of the case to the opening where thewelding takes place. However, this thickness is excessive for thepressure-resistant function required of the body part, and in fact,from the viewpoint of material cost reduction and weight saving,it can be said to be wasted thickness. Therefore, we devised adrawing process and succeeded in reducing the thickness of thebody to that required for pressure resistance, while
maintaining the thickness required for welding in the A section.

Thicknessrequiredfor welding

Evaluation technology

Process validation for true quality assurance[Example] Metal flow analysis
The lids of lithium-ion batteries are required to have various advanced functions and for this reason,complex shapes are formed by cold forging. If we judge the quality of the formed surface shape only
by its dimensions and appearance, we cannot guarantee quality in stable mass production andunder severe market usage conditions. Therefore, we observe and analyze the metal flow of theformed cross section to evaluate and judge whether the forming is smooth and stress-free. If theforming is under strain, wrinkles will be generated inside, which will develop into cracks in the future,and the product will not be able to fulfill its function. In this way, we evaluate the adequacy of theprocess and assure quality.

We participate from the initial development stage to understandthe truly necessary functions and propose the most suitableprocessing method and shape to realize them, thereby contributing
to maximize value for our customers.

Robust design

High quality and low cost
*The photo has been blurred.

[Example] Safety valve for lithium-ion battery
Lithium-ion batteries are equipped with a function called a safety valve to prevent explosion dueto some abnormality. If the internal pressure of a battery rises above a set value due to a shortcircuit or other problem, the safety valve opens and releases the pressure to avoid the risk ofabnormal heating, or even an explosion or fire. On the other hand, the safety valve must remain
sealed and not be activated by pressure fluctuations caused by normal charging and discharging.
In order to realize these functions in mass-produced products, direct countermeasures against
various error factors that disrupt the functions would result in high costs, including management
costs. Therefore, with the concept of robust design, we pursue safety valve design that is least
affected by error factors, as well as tooling and process design for press forming of such shapes.
As a result, we have achieved both stable high quality and low cost.

In-house manufactured toolingPress forming analysis

Start-up time reduced by CAE analysis[Example] Tooling design for rectangular lithium-ion battery case
A rectangular case is formed by drawing a single flat plate through several processes. This process
results in a complex interplay of stress and strain in the material. The key point of tooling design is tocontrol them well. By proceeding with design on CAE based on know-how accumulated over manyyears, we are able to reduce trial and error and significantly shorten the start-up period.

Maximizing the benefits of in-houseproduction of molds and dies, which
are the essential to press work

The advantages of in-house production include the accumulation of know-how, quick delivery,
and cost reduction. We also see sharing information by working as a team as an important
advantage. This information refers to the level of importance and urgency of each project, as
well as its purpose and intent. Sharing this information among all processes and working with thesame awareness is linked to expanding the scope of our responsibility.

Maintenance Activity
Maintain the best condition

Slogan"Turning factories into showrooms.""The world's most beautiful handling of molds and dies."
Promotion of 7S activities

In order to build quality in a process, it isnecessary to keep tooling and equipment ingood condition at all times. Preventive
maintenance is essential for this purpose. To
avoid overlooking even the smallest signs oftrouble, we have established various
inspection standards and monitor conditions.
We then make sure that the tooling andequipment are always performing at their best.

We have been working on 7S activities byadding "Safety" and "Sense" to thegeneral 5S (Sorting, Setting-in-Order,Shining, Standardizing, Sustaining theDiscipline). “Safety” is the first priority ineverything we do. Only when safety isensured can good work be done. We havealso added "Sense” to encourageemployees to exercise their creativity tomake their workplace more exciting andenjoyable through innovative ideas.

Be prepared for any eventuality
No matter how much effort is put into theaforementioned "preventive maintenance,"
there are cases of breakdowns that can berestored in a short period of time or
unexpected failures that lead to production
interruptions. In such "what-if" scenarios, it isnecessary to be prepared to recover as
quickly as possible. Specifically, this includes
preparation of standard documents such as
troubleshooting and manuals, andmanagement of spare parts.

Training
Maintenance activities also have a great deal
to do with improving the skills of employees.
Employees' skills are improved by not only
operating tooling and equipment in daily
production activities, but also by learning
about their structures and theories andacquiring higher-level maintenance methods.
Various study sessions are held for thispurpose, and the results of the improvement
are also reflected in personnel evaluations.

As our business performance expanded, the size and shape of our organization rapidly changed, and in2010 we renewed our management philosophy and published "Management Philosophy Handbook." Evenif we have unrivaled technology and equipment, it is our people who will master them and pave the way tothe future. Based on our management philosophy of "Through a virtuous cycle created by the selfactualization of each member, we strive to delight our customers, employees, and society to contribute to
the future of the Earth," we will continue to push forward with a focus on management that places"employees" at its core.
Since the time of our founder, the "spirit of challenge" has consistently flowed through our company. We
got ahead of the competition in the automotive battery business because we embarked on the new field
when our cellular phone battery business was at its peak.
In January 2019, we announced our "Long-Term Vision 2030" at the first meeting of the year for all
employees. With the mission of “Giving shape to happiness through manufacturing“ in mind, this long-termvision was drafted by the members who would be the next generation of management executives, aiming
to build the FUJI brand trusted around the world with its comprehensive manufacturing capabilities.
In order to achieve this vision, it is essential to develop a strategy to evolve our high value-added
management, which has been nurtured through a history of reforms, into strategic diversification
management. Grounded in our disciplined organizational culture, we will maintain our high value-added
management through the expansion and development of existing businesses, while aiming for the nextstage through strategic business plans, such as the development of new businesses with an eye tooverseas expansion, and furthermore, the development of "manufacturing-related businesses" that sell
“experiences" other than "products.” Such a vision cannot be achieved simply by imposing it on employees
from the company.

One naturally returns the next

from the former generation.

To have motivation and support

Fostering a corporate culture to achieve our visionFirst of all, it is necessary to foster a work environment where individual employees can positively tackle
their daily work with a system in place that motivates and supports them to “try their best. Then, when thecompany sees and evaluates their efforts properly, it will lead to a sense of individual achievement as well
as a sense of the value of their existence. Self-actualization gained through the company’s support isreturned to junior members, thereby forming the spiral of growth over generations. The accumulation of thespiral of self-actualization will help Fuji Springs to grow into an indispensable company, and at the sametime, it will enhance the status of being a member of Fuji Springs.
By establishing a corporate culture that encourages continuous self-actualization, we will become acompany in which all employees can be proud of their work. We will make company-wide efforts to achieve
this goal as an indispensable task for the achievement of our vision.
“Next step should be taken when business is strong.”
As our predecessors have demonstrated, the future lies ahead of us if we continue to challenge ourselveswith an eye to the future. We must not be complacent about good performance but must continue to takeon new challenges, always looking for new areas of business. The establishment of Satellite Office Nagoyaand FUJIHATSU TECH (Suzhou) Co., Ltd. in Jiangsu, China, were the developments with an eye toward
our next move. We also completed our construction of a new plant in Kameyama, Mie Prefecture in 2020.
This was to be close to our customers, to respond quickly, and to ensure a stable supply of locally
produced, locally consumed products.
We are confident that Fuji Spring’s progress toward becoming a 100-year company will be more solid
than ever as all employees work together to become a forward-looking and challenging corporate entity.
