In recent years, sales of electric vehicles (EVs) have been increasing rapidly and are expected to grow even more steeply in the coming years. As a result, global automakers are announcing the discontinuation of internal combustion engine (ICE) vehicle production.

This shift has prompted companies previously involved in ICE vehicle manufacturing to quickly pivot toward the EV market by investing heavily in production facilities and research and development. Among the core components of EVs, batteries and motors are expected to see especially rapid technological advancements.

At Dyna, we have been supplying punching oil to domestic and international manufacturers of battery components and motor cores for several years. We are committed to providing punching oil optimized for each production line, and we continue to receive increasing inquiries from companies in the industry.

The motor core is a key component that comprises the stator and rotor of a motor, playing a critical role in generating electricity. It is widely used not only in automobiles but also in home appliances, industrial machinery, and various power tools.

Motor cores are typically produced by processing and laminating thin sheets of electrical steel. This lamination reduces eddy current losses and prevents overheating caused by induced currents within the core.

When electric current flows through a coil, a magnetic field is created. Interrupting this current generates a counter-electromotive force (back EMF), due to the inertia of the electric current that attempts to continue flowing. This phenomenon causes molecular motion and eddy currents inside the core, leading to heat generation. To mitigate this, thinner and more precisely laminated cores are preferred.

As thinner and more durable steel materials have been developed, there is a growing demand for high-performance punching oil that can withstand the heavy loads of dies weighing several tons and high-speed punching operations exceeding 400 strokes per minute. For high-quality production, it is essential to use punching oil that can protect the die, remove metal particles, prevent discoloration of raw materials, and maintain the overall integrity of the manufacturing process.

We Dyna Co., Ltd. is continuously dedicated to developing high-performance punching oil technologies and has earned recognition for its expertise by supplying to a wide range of domestic and international companies.

If you are looking for punching oil with superior performance and quality compared to your current solution, or if you need technical consultation, please feel free to contact us anytime.
