ISHIGAKI SHOUTEN Inc.

Small specialist factory, manufacturing copper products right here in the city for 70 years!

As copper fabrication specialists, we provide transformer and control panel manufacturers in the power equipment industry with a wide range of copper components. Since our founding in 1948, we have grown with the development of the electric power industry, first by starting out the fabrication industry. Through active capital investment and human resource development, we have gone on to expand the range of materials we process to include copper, brass, and aluminum. Taking an earnest approach to processing copper and brass, we have devoted ourselves to mastering a wide variety of processing techniques, not only cutting and turning, but even bending and stamping as well. Our problem-solving skills have developed with the technical capabilities of our multi-skilled employees and through our integrated production. The strengths enable our one-stop service to accommodate tight deadlines with high-quality copper products from a single-piece orders.

Production Examples

  • Processing Applicable Range (Lot, Size/Shape, Material)

    Lot: Orders from a single unit. We also have handled mass production of up to several thousand units.
    Size/Shape: Plate thickness t 0.2-30 mm, diameter of 6-120 mm (round rods, disks), and lengths up to 3,000 mm
    Material: C1100 and other copper materials

  • Copper Processing (Cutting, Turning, Stamping, Bending, Rolling, Etc.) and Integrated Production

    Not only do we handle cutting and turning, we can complete a wide range of processes in-house, including bending, rolling, and stamping. Making full use of our extensive facilities such as machining centers, bending machines, and press machines, along with our network that has been a key factor since the company was established, we are able to handle orders for copper products as low as a single unit, with quick turnaround as well.

  • Copper Bus Bar: Processed Sheet Metal

    Lot: 1 to 300 pieces
    Thickness: 3.0 to 40.0 mm
    Total Length: Max. 2,000 mm
    Material: Pure Copper (C1100/C1020)/Brass/Aluminum/Chromium Copper/Beryllium Copper

  • Copper Rod: Processed Components

    Lot: 1 to 3,000 pieces
    Thickness: Diameter 10 to 100 mm
    Total length: Max. 1,000 mm
    Material: Pure Copper (C1100/C1020)/Brass/Aluminum/Chromium Copper/Beryllium Copper

  • Copper Plate:Machined Components

    Lot: 1 to 3,000 units
    Thickness: Diameter 10 to 100 mm
    Total length: Max. 1,000 mm
    Material: Pure Copper (C1100/C1020)/Brass/Aluminum/Chromium Copper/Beryllium Copper

Responding to climate change

Toward reducing greenhouse gas emissions

<< Obtained SBT certification for small and medium-sized businesses >>

[Contents of reduction target]


●Reduce Scope 1 and Scope 2 greenhouse gas emissions by 42% in 2030 compared to 2021

●Work to understand and reduce Scope 3 emissions

*The above target is certified at the 1.5℃ level, which is the most ambitious level that can be certified using the current process.


Base year GHG inventory

The CO2 emissions for the base year are as follows.


Base year: 2021

●SCOPE1: 13.7 tCO2

●SCOPE2: 79.8 tCO2


Analysis of risks and opportunities from future climate change

We have assumed the risks associated with future climate change scenarios and opportunities to respond to them as shown below.


【risk】

● Fear of price hikes in material procurement

●Delays in material procurement and delivery due to logistics suspension due to urban floods, etc.

●Delays in replacing equipment with environmentally friendly equipment, etc.


【opportunity】

● Demand for new energy infrastructure such as renewable energy will increase, and the amount of products handled will increase.

●New low-carbon energy infrastructure will increase the need for advanced processing components, increasing the added value of products.

●Working toward SBT level targets will raise awareness of reducing environmental impact within the company, and lead to reductions in energy costs through reduction activities.

●Promoting our company’s environmental initiatives will lead to securing excellent human resources and improve corporate value.


Interview

Background leading to participation in this project

Our company has established an internal structure to introduce an environmental management system. Since it coincided with this project, I participated because I thought there would be an interaction that would lead to the visualization of waste while establishing a system.


Observations and impressions after participating

We received an explanation from an expert about the impending global movement towards carbon neutrality, received guidance on how to narrow down the data we collect and how to measure it, and learned how much energy our company uses. I checked it in detail. I thought I knew everything financially, but now I have a more detailed understanding than ever before. In addition, although I felt that it would be difficult to achieve goals when setting goals, I felt it was meaningful to be able to prepare concrete data that would allow us to promote our efforts in order to acquire new customers, such as in the renewable energy field. Masu.


Future proposals from the company

Since our products are used in electrical equipment and other power infrastructure that is essential to modern life, we were keenly aware of the ripple effect that our efforts to become carbon neutral would have. Although each of the energy amounts we identified this time was small, there were many hints that could lead to reducing waste and increasing efficiency. We would like to utilize the concrete data we have obtained this time to reduce greenhouse gas emissions at the manufacturing stage and improve social value. By accumulating these efforts, we hope to grow into a company that contributes to fields such as renewable energy, which are essential to achieving carbon neutrality.
