[Explanation Material] What is buff polishing? has been registered.

One of the metal surface treatment methods, buff polishing, explained by a stainless steel container manufacturer!

The surface of the beautiful stainless steel container reflects like a mirror. Did you know that this beauty is not a characteristic of the material itself, but rather something artificially created? Generally, the surface of stainless steel containers is polished to a shine by a method called buff polishing, done by human hands. Here, we summarize a type of polishing method used to finish the surface of stainless steel, known as buff polishing.

BA material, 2B material, buff polishing, electrolytic polishing... A grand reveal of stainless steel surfaces that cannot be discerned by the naked eye!

Smooth, rough, silky... Depending on the material and surface finish, stainless steel shows various appearances. However, it is not possible to see what the actual surface looks like just by visual inspection. Therefore, this time, we will introduce photographs of stainless steel surfaces taken using a scanning electron microscope (SEM). *What is a scanning electron microscope (SEM)?* Unlike optical microscopes (such as magnifying glasses and general microscopes) that use light, a scanning electron microscope uses electron beams. It allows us to clearly see fine surface structures that cannot be observed with optical microscopes.

Stainless steel is a metal that is "difficult" to rust!

We sometimes receive inquiries from customers saying, "Even though it's made of stainless steel, it rusted quickly." Stainless steel, as the English words "Stain (rust, corrosion) + less (less) + steel (steel)" suggest, is an alloy of iron that is highly resistant to rust. While it is much less prone to rust compared to regular iron, it is not completely rust-proof. This PDF document summarizes "Why is stainless steel resistant to rust?", "What causes rust on rust-resistant stainless steel?", and "What are the rust prevention measures for stainless steel containers?" You can view it immediately by downloading the PDF.

Shall we process not only the container but also the lid to make it easier to use for connecting to devices and for the input of raw materials, etc.?

Stainless steel containers can be used for various purposes by customizing them, not only for storing raw materials but also for incorporating them as machine parts into equipment, connecting containers to facilities, and using them for feeding raw materials, among other applications. When customizing, we can also process the lids in addition to the containers. Here, we have summarized examples of custom-made lids for our stainless steel containers, the basic types of lids, and various lid processing options. At our company, we design and manufacture the optimal "lid" tailored to your specifications, usage environment, and applications, starting from just one piece, to ensure that our customers can use stainless steel containers comfortably.

SPACECOOL Inc. was selected as one of the top three companies from over 1,500 applications across more than 100 countries in "The Liveability Challenge 2026," a global sustainability initiative hosted by the Temasek Foundation and operated by Eco-Business, and received the Investment Prize. The Liveability Challenge (TLC) is a global initiative that evaluates innovative solutions aimed at addressing urgent sustainability challenges in urban tropical regions. Our company was the only finalist from Japan in the Cool Earth category, which focuses on responding to climate change and heat stress. During the grand final held in Singapore on May 20, 2026, we made our final pitch on cooling solutions for tropical cities and received the Investment Prize. Encouraged by this award, SPACECOOL aims to use this opportunity to implement sustainable cooling solutions in the Southeast Asia region and further accelerate improvements in global heat-related challenges.

Piab has launched the energy-saving vacuum control solutions "piSAVE ESS Standalone" and "piSAVE ESL Standalone." The energy-saving technology proven on the piCLASSIC Neo platform can now be flexibly implemented as standalone units, making it easy to integrate into various vacuum systems. Both products adopt a fully air-operated, self-regulating design, eliminating the need for external control or programming, while significantly reducing compressed air consumption and achieving high-efficiency vacuum performance. ■ piSAVE ESS Standalone An energy-saving solution optimized for highly sealed workpieces. It automatically controls the supply of compressed air to maintain the set vacuum level, resuming air supply only when necessary, thereby minimizing energy consumption. ■ piSAVE ESL Standalone An energy-saving vacuum control unit developed for workpieces that are prone to leaks. It automatically adjusts the supply pressure according to the amount of leakage, achieving stable vacuum performance and low air consumption.

Change 2: Scope 3 emissions have become an important theme in ESG disclosures. The challenges of English translation that Japanese companies often face For example, the following issues are likely to arise: - Misalignment of definitions (Upstream/Downstream) - Misunderstanding of the scope of inclusion - Confusion with "Value Chain" - Ambiguity in category classification - Divergence from reporting standards (GHG Protocol) Key points for English translation In the translation of Scope 3, the following points are crucial: - Prioritize the use of "Value Chain Emissions" - Clearly state when aggregating with Scope 1 and 2 - Include "Upstream / Downstream" with an awareness of upstream and downstream - Use the "15 categories" from the GHG Protocol as guidelines - Limit the use of the term "Supply Chain" to "upstream" only Our company utilizes the YIYO translation management system for integrated management to standardize the management of Scope 3 terms and categories, addressing the specific issues related to Scope 3 disclosures.

In recent years, many Japanese companies have been strengthening their information disclosure with an awareness of overseas ESG evaluation agencies and foreign investors. However, in practice, when producing English versions, several issues are often observed: - Terminology varies from document to document - While it may be coherent in Japanese, it becomes ambiguous in English - There is a lack of numerical explanations - Expressions unique to ESG become unnatural Key points to pay particular attention to are: 1. Avoid "we are making efforts" 2. Clarify the subject 3. Be cautious with "under consideration" 4. Standardize ESG terminology What is important in ESG English adaptation is not just "translation" but "consistency of expression": - Whether ESG-related terms align with international expression and disclosure standards - Whether quantitative information and numerical explanations are sufficient - Whether consistency of expression is maintained throughout the document - Whether the tone and structure are appropriate for investor and evaluation agency disclosures What our company emphasizes: We focus on ensuring that the English is easy to understand for overseas readers and sounds natural as ESG disclosure. To achieve this, we utilize YIYO to: - Standardize ESG terminology - Maintain continuity with past expressions - Ensure consistency between numbers and text - Manage translation quality.

We support various rubber materials such as CR, EPDM, NBR, silicone, and fluororubber for punching processing. We can select materials and process various shapes according to the usage environment, starting with applications for packing and gaskets. Rubber materials are used for a wide range of applications, including gap filling, water and dust prevention, and cushioning materials. In particular, packing and gaskets are used to prevent leaks of water, air, and oil by placing them between parts to create a tight seal. The type of material varies depending on the location and application. For example: CR: For cushioning and general purposes EPDM: For outdoor environments NBR: For environments with oil Silicone: For high-temperature environments Fluororubber: For chemicals and high-temperature environments Each material has its own characteristics. We also support material selection according to the application. We choose processing methods based on the application and shape. Services offered: - Punching processing - Hole processing - Ring shape processing - Complex shape processing - Packing processing - Gasket processing - Bonding processing
