The environmentally friendly special cleaning G-Eco method has been further powered up, strengthening measures against the novel coronavirus (COVID-19)!

A cleaning agent that removes mold, tar, and dirt from inside and outside buildings without damaging building materials and without harming plants, animals, or the environment. It can also be used on wood surfaces.

It removes mold and algae, and also addresses the removal of viruses and bacteria. It restores the darkening of wood components, lignin, caused by ultraviolet rays, returning the wood's color while simultaneously eliminating mold. This cleaning agent is not just a mold remover that decolorizes mycelium and spores; it thoroughly eliminates mold from the root and can suppress recurrence in the long term. By having separate mold removers for wood and other materials, it achieves cost reduction, environmental consideration, and efficiency in work processes simultaneously. It uses components that are also used in food additives and is environmentally friendly. It does not affect plants or animals. It can be used not only on concrete, boards, stone materials, resin, and painted surfaces but also on wooden parts (unpainted wood). 【Usage Examples】 It can be used in food factories, beverage factories, seafood processing plants, dairy farms, pig farms, poultry farms, hospitals, nursing facilities, public facilities, bathing facilities, sports clubs, schools, kindergartens and daycare centers, office buildings, hotels, supermarkets, residences, indoor wallpaper, sukiya gates, wooden decks, and more. *For more details, please download the catalog or feel free to contact us.

For equipment maintenance and removal of grease from parts! A cleaning agent that removes oil and dirt from inside and outside buildings without damaging materials and without harming plants, animals, or the environment.

Degreasing cleaning can be performed on cutting processing coolants (cutting oils), machine oils, and CVT oils. It reduces the risk of rusting metal by removing oil stains while protecting the metal. It can be used in conjunction with various cleaning machines such as parts washers (cleaning machines, high-pressure washers, bubbling, ultrasonic, power washers), and floor cleaning machines. You can utilize its features in various applications including floor cleaning, parts cleaning, various types of cleaning, and pre-cleaning for painting and plating, among others. It removes oil and dirt without harming or damaging the material, from kitchen grease to industrial oil stains in factories. The main ingredient, sodium hydroxide, is designed for safe and secure use. As an industrial/industrial cleaning agent that considers workers, materials, living organisms, and the environment, it offers high safety and environmental friendliness, making management and use easier, leading to increased productivity. 【Application Examples】 It can be used for equipment maintenance, degreasing cleaning, parts cleaning, surface treatment degreasing, floor cleaning, in manufacturing plants, maintenance shops, gas stations, restaurants, and more, from kitchen grease to industrial oil in factories. *For more details, please download the catalog or feel free to contact us.

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 even 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.

● The production time for cast prototypes can be shortened! Since model making is not required, the production time for 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! Different products, such as similar shapes or varying dimensions, can be molded at the same time in one molding process. This allows for the verification of multiple types in a short period.

Last month, we held a spring safety conference hosted by our company. We have compiled the details and atmosphere of the day into a PDF. We would appreciate it if you could take a moment to read it.
