The unified brand for Risho epoxy mold products has been registered as "RISHOCAST."

We design and manufacture transformers with "custom specifications" for each customer.

The winding is reinforced with glass fiber, and after setting it in a mold, it is produced using the "mold method vacuum impregnation method," where epoxy resin is impregnated while "vacuuming." The epoxy resin is endowed with self-extinguishing properties, so there is no concern about combustion, secondary fires, or explosions. The epoxy resin is a low-viscosity type that does not contain fillers such as silica. Therefore, the resin penetrates even into the interior of the winding. Due to the vacuuming process, no air bubbles enter the resin, making it a highly reliable insulation method with no concern for partial discharge (corona) that could arise from this. The winding has a monolithic molded structure, making it resistant to moisture and preventing moisture absorption. The glass fiber-reinforced winding has excellent mechanical strength, allowing it to withstand stress during voltage switching. It can be made smaller and lighter than oil-insulated transformers, and maintenance inspections are also easy. *For more details, please download the catalog or contact us directly.*

• Other energy equipment

50% energy savings by replacing transformers that have reached their update period.

This is a distribution transformer with excellent energy-saving performance that significantly reduces "no-load loss," which corresponds to standby power. The capacity of the transformer is determined based on the peak power consumption expected at the facility. Therefore, there can be a significant deviation from this capacity during nighttime, holidays, or certain seasons. In particular, in office buildings, the average load factor of the transformer, which is the ratio of average power to maximum power, is estimated to be around 30 percent, indicating that the time periods when standby power is at its maximum likely account for a considerable proportion. Thus, if you replace the 30-year-old transformer that has reached its renewal period with a Risho amorphous molded transformer, you can achieve a 50 percent energy saving and an annual reduction of 8 tons of carbon dioxide.

• Other energy equipment

The only one in the world. "Complete solid insulation" that does not use oil or SF6 gas.

It is a disaster-resistant and environmentally friendly capacitor.

● The production time for casting 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 creating 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 variations in dimensions, can be created in a single molding process. 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 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.

Dear Sir/Madam, I would like to express my congratulations on the continued prosperity of your company. Thank you very much for your exceptional support. We would like to inform you that our company will be closed for winter holidays during the following period. We apologize for any inconvenience this may cause and kindly ask for your understanding. 1. Winter Holiday Period From Thursday, December 28, 2023, to Thursday, January 4, 2024. 2. Business Operations After the Winter Holiday Period We will resume normal operations from Friday, January 5, 2024.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm. Please feel free to contact us for more information!

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.
