Battery manufacturers need stepper motors, in lithium battery winders need stepper motor and planetary gearbox combination, of course, you can also choose planetary gearbox stepper motor, we provide a variety of planetary gearbox stepper motors (contact email: anwenqq2690502116@gmail.com).
It is understood that the current cell manufacturing of power lithium batteries is mainly divided into two processes: winding and lamination, of which cylindrical and prismatic batteries are mainly produced by winding process, while pouch batteries are mainly produced by lamination process. Since the winding process can achieve high-speed production of battery cells through the speed, and the speed that lamination technology can improve is limited, the current domestic power lithium battery is mainly based on the winding process, so the shipment of the winding machine is greater than that of the laminator.
At present, with the rise of domestic battery cell enterprises, the process of replacing imports of domestic equipment is also accelerating.
Based on some high-end products, domestic enterprises have driven the continuous improvement of the overall equipment technology level and gradually caught up with foreign countries. While the product performance of domestic enterprises is constantly improving, the price and service advantages are gradually obvious compared with foreign countries, and the price of foreign brand winding machines is 20%-30% higher than that of domestic high-end brands. In terms of comprehensive cost and technology, the competitive advantage of domestic lithium battery equipment is constantly expanding.
