                                     Product Display

                                    Product Advantages

◆Compatible with 156-230mm, 5BB-20BB battery cells.

◆ High-speed electric cylinder battery cell sorting and placing.

◆Flux infiltration, easy maintenance.

◆ Unique flexible pressure holding welding tape mechanism.

◆ Infrared heating, segmental welding; closed-loop control of welding temperature and power, gentle temperature rise, small thermal shock, effectively reducing the fragmentation rate of battery cells.

◆Satisfy the chamfering of the battery sheet to face forward and backward respectively, and meet the chamfering before and after welding at the same time.
