Transforming
Manufacturing

Striving for Global Niche Leadership

Our Mission

Our company has long maintained stable operations, serving some of the most reputable companies in Japan’s automotive industry.
However, today’s tooling industry is facing intense price competition.
To secure our future, it is essential for us to take on the challenge of expanding our presence in the global market and emerging as a winner.

Achieving this will require a complete transformation of our processes – from design to manufacturing.
Developing unique technologies found nowhere else and establishing new business models will be our mission going forward.

Innovation & Challenge

Transforming the Future of Manufacturing and the Environment with Cutting-Edge Technology

In addition to conventional die-casting mould manufacturing, we are pioneering innovation through our proprietary technology by developing porous moulds using metal additive manufacturing (AM) with 3D printers.
By utilizing the microscopic pores on the mould surface — a key feature of porous moulds — we can add new functionalities, creating entirely new types of moulds.
This opens up infinite possibilities for manufacturing and enables the creation of a wide variety of products.
Porous mould technology is expected to play a significant role not only in the automotive industry, but also in fields such as aerospace and healthcare.

Our new technology enables products and functions that were difficult to achieve with conventional moulds.
It also allows us to offer new value propositions to our customers, such as:

Reducing the use of release agents, improving workplace environments

Shortening casting cycles, leading to significant cost reductions

Furthermore, die-cast products
manufactured using our moulds help our customers reduce the number of components, achieve weight reduction, and promote recyclability.
This contributes to better fuel efficiency and improved parts reuse — addressing global environmental challenges.

Our research and development efforts are indispensable in tackling some of the most pressing global issues, including environmental and energy challenges and aging societies.

Business
Diversification

Launching New Ventures and Expanding Our Business Horizons

In today’s competitive market, manufacturing moulds alone is no longer enough to stay ahead. To differentiate ourselves and strengthen our brand, we must leverage our deep manufacturing expertise and the capabilities of our moulds to create innovative products—driving true business diversification.

In our core mould business, we will continue developing a broad range of products for the global market, proactively introducing solutions tailored to the unique needs of each region. By embracing cutting-edge technologies, we aim to deliver high-value products that showcase our distinctive strengths. Looking ahead, we also plan to evolve our factory into a Smart Lab to enhance product promotion, sales activities, and productivity.

As automation with robotics, IoT, and AI becomes increasingly costly, we will accelerate our environmental improvements by transforming our factory into a showroom—a product in itself. We will also commercialize the internal innovations we create to support production, launching them as S-LABO products. These solutions will be offered not only in Japan but also worldwide, establishing a new pillar of our business.

We are committed to elevating the status of our entire industry and contributing to a more convenient and efficient world. As professionals in the mould industry, our mission is to deliver the best solutions possible.

FAQ

  • Q1. What is die casting?

    Die casting is a manufacturing process where melted metal—often aluminum—is injected into a mould to create a specific shape.
    It’s commonly used to make things like automotive engine parts and metal smartphone covers.

  • Q2. What is a mould?

    In simple terms, it’s a “metal mould” used to form products.
    Just like using a cookie cutter, molten metal is poured or injected into the mould so the same shape can be produced again and again.

  • Q3. What are die-casting moulds made of?

    They are mainly made from extremely hard steel known as “tool steel.”
    Since the mould must endure very hot aluminum thousands of times, it needs to be both strong and highly heat-resistant.

  • Q4. How long does a mould last?

    It depends on how it’s used, but moulds for aluminum die casting typically last between 50,000 and 100,000 cycles.
    With proper maintenance and careful operation, they can last even longer.

  • Q5. How expensive is a mould?

    The cost varies depending on the product’s size and complexity.
    Even small moulds can cost several million yen, while large automotive moulds can cost tens of millions.
    They truly are the “core of manufacturing.”

  • Q6. How long does it take to make a mould?

    It usually takes 2 to 6 months from design to completion.
    Achieving the required precision involves multiple rounds of machining, assembly, and test runs (called “tryouts”).

  • Q7. What causes moulds to break?

    The main causes are heat and pressure.
    Repeated exposure to high-temperature aluminum can lead to cracks, wear, or surface damage.

  • Q8. Can moulds be repaired?

    Yes.
    Cracks and scratches can be repaired through welding, grinding, and polishing.
    Fixing issues early helps significantly extend a mould’s lifespan.

  • Q9. What’s inside a die-casting mould?

    Inside the mould are cooling channels that cool the molten metal and ejector pins that push the solidified part out.
    It has a very precise, complex structure—almost like the “heart” of a machine.

  • Q10. Why is die casting used so often?

    Because it allows manufacturers to produce high-quality parts quickly and in large quantities.
    It creates smooth surfaces and accurate dimensions, which reduces the need for extra processing.
    Die-cast parts are found everywhere—from cars and appliances to cameras.
