Attention customers struggling with "high-temperature" manhole gaskets!

On November 1, 2015, the "RCF regulation" was implemented, which essentially prohibits the use of sealants made from ceramic fibers. The commonly used alternative is "biodegradable fibers." Several years have passed since similar products have been released by other manufacturers, but we have recently been hearing feedback from job sites such as the following: "The material is weak during installation." "When the lid is opened, it crumbles." The MacThermo Bio-HD series is a product that has been reinforced by knitting each weak thread with metal wire, making it stronger than previous versions. It has already been successfully used in coke ovens at steel mills, so please check the details below!

[To the owners of parking lots and parking lot construction companies] "I'm worried about the possibility of colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those facing sidewalks or roadways are particularly prone to dangerous incidents such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures at various sites and alerts the surroundings with LED lights and buzzers. The system consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *When using the exit warning system, we kindly ask customers to arrange for the switching power supply (24V), LED rotating light, control panel, circuit breaker, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. [Contents Included] ○ Vehicle Exit Warning System Configuration ○ Comparison Table of Exit Warning Sensors ○ Four Modes ○ Wide Range of Applications ○ Customer Feedback ○ Appearance Diagram / Specifications ◎ For more details, please contact us or download the catalog.

● 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.

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 to 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 you require a detailed technical explanation, please contact us.
