The explanation document on the insulation method for stainless steel tanks with jackets has been registered.

I have summarized the insulation method for a jacketed stainless steel tank that can maintain temperature by circulating water or steam in the outer jacket.

Using a stainless steel tank with a jacket (outer shell), when hot water or steam is circulated inside the jacket, the surface of the tank also becomes high in temperature. This can lead to an increase in the working environment temperature due to heat radiation from the tank, or if the room temperature is low, it may take a long time for the tank temperature to rise. Additionally, there is a risk of burns if someone accidentally touches the high-temperature tank. Here, we will introduce methods for insulating the jacketed tank.

We have compiled stainless steel containers that are easy to clean and help prevent foreign matter contamination.

Have you ever experienced the following issues while using stainless steel containers? - Contents or dirt getting trapped in the rim of the container, making it impossible to remove. - Dirt accumulating on the handle, causing inconvenience. - Taking a long time to remove dirt or cleaning solution that has entered the gaps of the container during the cleaning process. When dirt or foreign substances get into the gaps of the container, they are difficult to remove. This not only prolongs the cleaning process but also the residual dirt or cleaning solution can lead to foreign matter contamination or cross-contamination. So, what kind of stainless steel containers can help reduce cleaning time?

I have summarized the important cleaning methods to make stainless steel containers last longer.

After using a stainless steel container, it is essential to clean the container. However, incorrect cleaning methods can cause scratches or lead to rust. Here, we will introduce important cleaning methods to help prolong the life of stainless steel containers.

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.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

We will be exhibiting at the "New Manufacturing and New Services Exhibition for Small and Medium Enterprises" from December 16 (Tuesday) to 18 (Thursday), 2025. Please feel free to stop by our booth. We look forward to meeting everyone.

Thank you very much for your continued support. Donaldson Japan Co., Ltd. will be closed during the following period: From April 25 (Saturday) to May 6 (Wednesday). Inquiries made during the closure will be answered sequentially after May 7 (Thursday). We sincerely apologize for any inconvenience this may cause. Thank you for your understanding and cooperation.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
