Crushing from molded runners to molded products! A dry crusher capable of crushing various plastics!

The dry grinding machine "CS Series" is a device that crushes various plastics, from molded runners to molded products like beer cases. It allows for the selection of the optimal hopper shape according to the size of the input material, and is designed with considerations for cleanliness and maintenance to accommodate small-batch production of various types. This grinding machine achieves cost reduction through parts sharing while maintaining performance quality. It is also capable of crushing large molded products when combined with a coarse crusher. 【Features of the Dry Grinding Machine "CS Series"】 ■ A lineup of 8 sizes of grinders, from small to large ■ Emphasis on cleanliness and maintenance ■ Possible reduction of costs necessary for grinding ■ A wide range of options to accommodate various grinding needs ■ Equipped with a safety limit switch *For more details, please refer to the catalog or feel free to contact us.

A cleaning unit that simultaneously performs cleaning and crushing!! Just by adding water and crushing materials, waste plastic is transformed into a valuable resource!!

The crushing machine simultaneously crushes and cleans by feeding crushing materials and water into it. Inside the crushing chamber, the materials are agitated and washed, creating a powerful cleaning effect. The dewatering equipment can rinse and clean any slight dirt that the crusher couldn't remove, followed by centrifugal dewatering. 【Features】 ○ Diverse lineup ○ Proposals tailored to customer needs ○ Combination of cleaning crushing and dewatering machines (can be used individually) For more details, please contact us or download the catalog.

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 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 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.

This is an air leak tester for battery cases of electric vehicles (EVs). The battery case has the characteristic of being "large with a significant internal volume, and its structure may deform due to internal pressure." As a result, air leak testing generates "noise caused by its large size and capacity" and "noise caused by expansion or deformation due to internal pressurization." To mitigate this noise, this device features a newly developed smoothing function and a linear fitting correction function used in combination during measurement. Additionally, to achieve low-pressure control that is difficult to manage and to expand flow for large volumes, we provide a bypass box (CBU-600) equipped with an electro-pneumatic regulator for precise pressure control and a pressurization valve with a large effective diameter to supply high flow rates. Measurement methods: Work-Work comparison, Work-Master comparison, Fixed Master comparison Measurement pressure range: 10 kPa, 20 kPa, 50 kPa (depending on specifications) Gauge pressure sensor accuracy: ±2% F.S. Differential pressure sensor accuracy: ±0.5% F.S. Group settings: 0 to 31 groups Power supply voltage / Power consumption: AC100 to 240 V / 100 VA
