New Energy Use of PI Film Solution: Advantages and Applications of Rotary Blade Die Cutting Machine

With the rapid development of new energy technologies, the demand for materials is also growing. Especially in new energy batteries, solar panels, and other products, special high-performance films are required as key materials. Polyimide (PI) film is an important material in these applications, which has excellent high-temperature resistance, chemical corrosion resistance, and electrical insulation properties, and thus has been widely used in the field of new energy. However, the key technology is how to efficiently and accurately process and shape PI film, and the rotary blade die cutting machine is an important equipment to solve this problem.

 Overview of Rotary Blade Die Cutting Machine

The rotary blade die cutting machine is a high-speed, high-precision die cutting equipment, mainly consisting of a frame, transmission system, die cutting system (including rotary blade), and control system. This machine is used to cut, crease, or emboss thin materials such as paper, cards, stickers, and films. In the application in the field of new energy, the rotary blade die cutting machine is particularly suitable for cutting and forming materials such as PI film.

Advantages of Rotary Blade Die Cutting Machine

1. High Precision Cutting: The rotary blade die cutting machine has extremely high cutting accuracy, able to accurately cut out shapes and sizes in accordance with design requirements, meeting the strict standards of new energy products.

2. Fast Processing: By using rotary cutting, the rotary blade die cutting machine is more efficient in production than flatbed die cutting machines, capable of achieving high-speed continuous production.

3. Strong Adaptability: The rotary blade die cutting machine can handle various thicknesses and materials of films, with strong adaptability to meet the requirements of different new energy applications.

4. Easy Maintenance: The machine structure is relatively simple, with easy and quick replacement of dies and rotary blades, and relatively low maintenance and operating costs.

5. Customization: Users can customize the cutting size and shape of the rotary blade die cutting machine according to their needs, making it adaptable to specific production line requirements.

Application Fields

1. New Energy Batteries: In the production of lithium-ion batteries and other types of new energy batteries, PI film is commonly used as a separator, insulation layer, etc. The rotary blade die cutting machine can provide precise cutting for these applications.

2. Solar Panels: PI film is also used in the manufacturing process of solar panels. The rotary blade die cutting machine can be used to cut films to meet the different sizes and shapes of solar panels.

3. Flexible Electronic Products: With the rise of wearable devices and flexible electronics, the demand for processing PI and other flexible materials continues to grow. The rotary blade die cutting machine provides the possibility for fine processing of these products.


The application prospects of PI film in the field of new energy are broad, but its processing challenges are not small. The rotary blade die cutting machine, with its precise and efficient cutting capability, has become an ideal solution for the processing of PI film. As new energy technology continues to advance, the reliance on rotary blade die cutting machines will also increase, driving the overall technological innovation and development of the entire new energy industry.
