Product Introduction

Advanced Shearing Technology: This machine is equipped with proprietary technology, delivering overall performance that exceeds industry standards. It offers excellent precision in cutting lithium iron phosphate (LiFePO4) electrodes and ultra-thin/ultra-thick power battery electrodes.

✅
Versatile Application: Designed for continuous cutting and rewinding of intermittent coating positive/negative electrode sheets, base copper foil, aluminum foil, isolation film, and aluminum-plastic film.
✅
Constant Tension Control: Features a pneumatic shaft with magnetic powder brake and photoelectric edge alignment for stable unfolding.
✅
Custom Windup System: Sliding shaft ensures uniform tension and synchronization across all strips, eliminating breakage. Settings are fully programmable via touch screen.
✅
Modular Blade Holder: Installed on a mobile cart for fast positioning and rapid blade changes, supporting both high-capacity and low-batch production.
✅
Burr-Free Results: Advanced roller shear blades utilize globally leading technology to ensure cut edges remain free of burrs.

Frequently Asked Questions

What materials is this machine compatible with?

The machine is designed for copper foil (5-20um), aluminum foil (8-30um), lithium iron phosphate electrodes, and various isolation or aluminum-plastic films.

How accurate is the cutting width?

The machine achieves a cutting width accuracy of ≤ ±0.05mm, ensuring high-quality output for precision battery manufacturing.

Can the machine run continuously?

Yes, the equipment is designed for 24-hour daily operation with a projected life cycle of no less than 10 years.

How is the tension managed during the rewinding process?

It uses a custom-designed sliding shaft and a touch-screen controlled tracking system to maintain constant tension and prevent material breakage.

What is the burr level after shearing?

Thanks to advanced roller shear technology, vertical burrs are kept ≤ 8um and planar burrs ≤ 12um.

Does the machine support quick product changeovers?

Yes, the modular blade holder system is mounted on a mobile cart, allowing for rapid mechanical positioning and fast blade changes for different widths.
