Motor Cores

The demand for motors is exploding due to the rise of electric vehicles. This trend is expected to continue long-term, and the stock prices of related companies are also steadily increasing.

Not only electric vehicles, but also many products around us use motors.
Motors are essential components in almost all household appliances such as refrigerators, air conditioners, and vacuum cleaners, as well as in industrial power generators like hydroelectric and wind power systems.

Punching oil is used in the manufacturing of motor cores, which are key components of these motors.
A motor core is a critical part that generates electricity in a motor. It is made by stacking several layers of products that have gone through a punching process.

The punching oil used in this process helps reduce friction during punching, provides excellent lubrication for more precise processing surfaces, and prevents various issues that could occur during stacking due to lubricant use.

Radiators

When we think of radiators, we usually imagine the cooling devices installed at the front of cars to cool the coolant. In vehicles, radiators serve as heat exchangers.

Through heat exchange (cooling hot components), radiators help maintain the engine temperature. They are used not only in cars but also in trains, airplanes, ships, and power generation facilities—essentially, anywhere an engine is used. Radiators are also found in household appliances like refrigerators and air conditioners, as well as refrigerated display units in grocery stores.

Radiators consist of numerous aluminum fins arranged horizontally or vertically at consistent intervals. Punching oil is used to punch these aluminum fins.

Although the punching oil used in radiators for air conditioners and refrigerators is of a quick-drying type, a separate drying process is still carried out.

Aluminum Disposable Containers

In the past, disposable containers such as lunch boxes in Korea were often made of aluminum. However, their usage has declined due to the rise of plastic containers.

Nonetheless, in other countries, aluminum is still considered less harmful than plastic. It is widely used for packaging baked goods and remains popular in party culture.

Since these disposable containers are often used for storing food, special care is required. The punching oil used in this application must consist of base oils and additives that are certified and approved by organizations such as the FDA.

Battery Case Components, Capacitor Cases, etc.

In addition to the three examples above, punching oil is also used in the production of electric vehicle battery cases and related components. Capacitor cases, which are parts of various electronic products, are also made of aluminum and are manufactured through punching processes that require punching oil.

Furthermore, punching oil is widely used across many other areas, including automotive parts, the internal mesh of microwave oven doors, electrical circuit breakers, and more.
