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 affecting the base material with heat. 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.

A "non-contact switch" that allows you to open and close doors simply by waving your hand, without directly touching the doorknob or switch! By adopting microwave technology, the risk of malfunction due to condensation in environments with temperature differences, such as cold storage warehouses, is significantly reduced. It reduces the risk of virus and bacterial infections in places where hygiene is a concern, such as food factories, hospitals, nursing facilities, and restaurant kitchens. 【Features】 ○ Reduces the risk of virus infection by allowing door operation without contact ○ Waterproof and dustproof (IP55 design), allowing the main unit to be washed with water (note: the wall surface (back side) is not applicable) ○ LED display and response sound allow for easy confirmation of detection status ○ Two pattern settings for one-shot and latch output are possible ○ The thinnest in the industry! Only 22mm thick! ◎ For more details, please download the catalog or contact us.

● 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.
