[Waterproofing Case Study] Coil for Hydraulic Valve for Outdoor Use

[Waterproofing Case Study] Coil for Hydraulic Valve for Outdoor Use

[Waterproof Electrical Component Processing Case] Improved yield due to poor water ingress into the coil! *Case study collection available.

We would like to introduce a case of waterproof processing for our waterproof electrical components, specifically the "coil for hydraulic valves." We received a consultation regarding frequent water ingress issues in coils for hydraulic valves intended for outdoor use, which resulted in poor yield rates. We conducted waterproof processing at our company to reduce these waterproof failures. Through material selection and trials, we have successfully eliminated the occurrence of waterproof failures, achieving a current zero incidence rate (as of April 1, 2019), resulting in a highly satisfactory outcome. 【Processing Materials and Equipment Used】 Materials: PA resin (nylon resin) Molding machine: 50t vertical insert *For more details, please refer to the PDF document or feel free to contact us.

Our job: Motor maintenance

Our job: Motor maintenance

A professional who revitalizes motors that have been in use for many years.

Motors are actively used as a driving force in various fields such as industrial machinery, generators, marine equipment, vehicles, and home appliances. Inside a motor, a wide range of parts are used, and these parts inevitably deteriorate due to aging and usage conditions. Parts that have been in operation for many years and have deteriorated can cause motor failures. However, by identifying the deteriorated parts and those that have caused failures, and by performing maintenance based on the know-how we have cultivated, there is a possibility to restore the motor to a condition close to new. When we take care of your important motor, we strive to restore it to the best possible condition and deliver it back to you, ensuring your satisfaction. Please feel free to contact us. [Contact Examples] ■ Dissatisfaction with the current company you are dealing with ■ Not knowing where to request repairs ■ Wanting to hear an opinion as a second opinion, etc. *For more details, please refer to the PDF materials or feel free to contact us.

The long lifespan of the motor is achieved through various coil rewinding methods.

The long lifespan of the motor is achieved through various coil rewinding methods.

The increasingly lost skills of motor maintenance are gaining renewed attention! Here, we introduce methods to achieve longer motor lifespans.

Our company has received various requests for the maintenance of different types of electric motors, and we have faced our customers' challenges with a track record of maintaining hundreds of units annually. In recent years, with the growing awareness of eco-friendliness, we are proposing the long lifespan of electric motors that our customers can adopt, specifically through "various coil rewinding maintenance." We sometimes receive inquiries such as "the electric motor we were using has been discontinued and is no longer available." By understanding the importance of various coils in electric motors and knowing the benefits of rewinding maintenance, customers can have the option of repair instead of being left with no choice but to discard a broken motor. Our company always strives to propose maintenance content from the customer's perspective. *For more details, please refer to the PDF materials or feel free to contact us.*

Leave it to us when it comes to coils.

Our company specializes in coil manufacturing. We primarily started with solenoid coils. Currently, the production of solenoid coils, toroidal coils, and others has shifted mainly overseas, resulting in a decrease in domestic production. Leveraging the experience and management systems developed during solenoid coil production, we offer air core coils, edgewise coils, and more. ■ November 2011: Mass production of reactor coils commenced ■ January 2013: Mass production of transformer coils commenced *For more details, please download the PDF or feel free to contact us.
