Announcement of the publication of the "Environmental Measurement and Analysis Comprehensive Catalog."

We support your technology from approximately 40 branches and offices nationwide.

Since our founding in 1958, we have been involved in engineering across various industries as a member of the Mitsubishi Materials Group. As a company that provides essential equipment technology for improving our customers' manufacturing capabilities, we continue to contribute to the advancement of manufacturing through "technology that supports our customers' technology." Furthermore, while we are engaged in plant engineering, we are also a manufacturing company that creates industrial machinery and equipment, enjoying the patronage of many customers. Additionally, based on the resource exploration, geological survey, and drilling technologies cultivated from our roots in the mining industry, we have many years of experience as a resource and environmental consultant. As a resource and environmental consultant, we offer "measurement and analysis," as a manufacturing company, we provide "consultation on the optimal introduction of machinery and equipment to plants," and as a construction company, we offer "consultation on the entire plant." We have the strength to provide one-stop solutions from approximately 40 branches and offices nationwide. We look forward to your inquiries.

• Mechanical Design

Essential for manufacturing that considers environmental concerns and complies with regulations, capable of various measurements/analyses - also selected as a "Zero Emission Challenge Company" by the Ministry of Economy, Trade and Industry.

Our company is in the construction industry, yet we have developed resource exploration, geological survey, and drilling technologies rooted in the mining industry. We have also provided various applied technologies as a resource and environmental consultant. In the environmental field, we can offer a consistent response from investigation to analysis to countermeasures for soil and groundwater contamination. Additionally, we can propose environmental measurements and countermeasures for production sites. In the energy sector, we are working to promote and disseminate ground heat utilization systems that excel in environmental and energy-saving properties. We participate in numerous large-scale projects, and in geothermal power generation, we have been selected as a "Zero Emission Challenge Company" by the Ministry of Economy, Trade and Industry, paving the way for a decarbonized society through innovation. 【Business Activities】 　■ Resource Consulting 　■ Environmental Consulting 　■ Energy Consulting *For more details, please refer to the PDF materials or feel free to contact us.

• Water quality testing
• Contract Inspection

● 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.
