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.

● 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 introduce the implementation results of the sensor technology developed by the Hotron Group, which has been cultivated over more than half a century, through customer case studies. In addition to automatic door sensors, we also offer a wide range of vehicle detection sensors and nursing/care sensors. Many implementation examples are also presented, so please take a look at the case study page.

Parking space management refers to the real-time display of parking availability and the management of efficient use of parking spaces. By utilizing Hotron's sensors, drivers can quickly discover available parking spaces, enabling efficient parking lot operations. For large parking lots, we recommend the "Floor Management Method" and "Block Management Method," which focus on cost reduction. Sensors are installed at regular intervals to count and manage the number of passing vehicles. This method offers the advantages of easy installation and low costs. 【Target Products】 - Vehicle Count Sensor CCS2 - Ultrasonic Sensor HM-UX2/UW2 For smaller facilities, we recommend the "Parking Space Management Method," where sensors are installed in each parking space to display availability with high accuracy. By providing reliable occupancy information, this method helps reduce unnecessary entry of new vehicles and ensures safe parking lot operations. 【Target Products】 - Occupancy Detection Sensor HM-UX2/UW2 - Occupancy/Pass Detection Sensor HM-LC6 - Occupancy Detection Sensor HM-LC7/LC7-FLS - Occupancy/Pass Detection Sensor HM-S6 - Occupancy Detection Sensor HM-S8
