The output rate of the production line that Schuler has sold to the South Korean manufacturer LT Precision is 2,000 housings per minute. This is equivalent to around half the battery cells installed in an average electric car. The delivery includes a cup press system, seven rework presses, and the corresponding tooling manufactured by the Schuler subsidiary Aweba.
Cylindrical battery cell housings with a length of 70 millimeters and a diameter of 21 millimeters are produced on the production line. First, the first press cuts round blanks from nickel-plated sheet steel, which are formed into cups in the same production step. In this process, material usage of over 90 percent is possible. The cups are then deep-drawn, stretched and trimmed in the automatic punching machines. Six parts per machine are put onto the outfeed conveyor at the same time. In the final work step, the cell casings are washed.
Production is scheduled to start on the line in 2024. The battery cell housings will be installed in electric cars from various manufacturers.
