We explain common cleaning concerns faced by those in the manufacturing industry in a comic format. Our company specializes in contract cleaning, primarily focusing on "contract cleaning" services. We have also built a new factory and can perform "hydrocarbon cleaning" with consideration for the environment. Recently, we have been addressing environmental issues more than ever, such as obtaining ISO 14001 certification and installing solar panels on our factory roof. Common concerns include: "I need to clean products longer than 4 meters." "I need help because our in-house cleaning capacity is overloaded." "I want to outsource cleaning because the investment in degreasing equipment is costly." If you have such concerns, please contact us, and we will respond appropriately based on the material, size, and quantity. *For more details, please refer to the PDF document or feel free to contact us.

• Contract Inspection

Specialized industrial cleaning service. We accept requests for degreasing of metals, electronic substrates, etc.

At Honma Industries Co., Ltd., we have introduced a custom-made large hydrocarbon cleaning device from Japan Field Co., and we use the high-performance hydrocarbon-based cleaning agent "NS Clean" for hydrocarbon cleaning solvents. Honma Industries' hydrocarbon cleaning machine combines cleaning ability through physical forces and drying capability based on boiling points. It allows for the selection of three types of physical forces: oscillation, rotation, and ultrasound. Due to its excellent vacuum drying capability, we perform vacuum drying after steam finishing cleaning. Areas that could not be fully dried with previous cleaning methods due to issues like stop holes and liquid pooling can be quickly dried under vacuum cleaning and drying, as the boiling point decreases. 【Features】 ○ Compliant with RoHS standards and ISO 14001 ○ Introduction of environmentally friendly hydrocarbon-based cleaning ○ Careful attention is paid to avoid scratches, scuffs, and dents during cleaning ○ Powerful trichloroethylene cleaning is also possible ○ Cleaning tests and analysis are available For more details, please contact us or download the catalog.

In civil engineering sites, there are many instances where sheet boards are used for temporary roads, access roads, heavy machinery work yards, material storage areas, and pedestrian pathways. Traditional steel plates are heavy, which can require large cranes or heavy machinery for installation and removal, increasing the workload depending on site conditions. Hyper CLT sheet boards are civil engineering materials made from wooden CLT for civil use. The 5×10 board weighs about 230 kg, and the 5×20 board weighs about 460 kg, making them lightweight and easy to handle even with small machinery, which allows for easier installation without the need for large cranes. They also contribute to reducing the burden of transportation, installation, and removal, as well as improving maneuverability on site. Recommended as a registered technology by the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A," it is suitable for companies considering civil engineering, civil use, and civil CLT. This material is easy to use for creative proposals in public works, such as alternatives to steel plates, common temporary structures, temporary roads, and curing for material storage areas.
