Drives for use in battery production must meet special requirements. All components, such as bearings or guides, where abrasion can occur must be designed in such a way that they prevent short circuits. They should also prevent conductive or disruptive particles from entering the production process. This is the only way to ensure the high quality of the battery cell.

Tox Pressotechnik from Weingarten was able to acquire the necessary expertise for a major order for the Korean chemicals group LG Chem. The Upper Swabian company supplied 333 tailor-made Tox power packs optimized for battery cell production. For these drives, some add-on parts and components were made almost entirely without copper, nickel and zinc, while others were made entirely without copper, nickel and zinc. The company manufactured other parts in stainless steel according to specifications. The pneumohydraulic drives are used, among other things, for bubble-free pressing of a foil onto the battery cell.

Tox Pressotechnik is now transferring the experience gained here to its electromechanical Tox ElectricDrive drives. These can be precisely optimized to meet customer requirements in battery production. "This makes us the only drive manufacturer that can offer both drive technologies at the highest level for battery production," explains Frank Ortmann, Business Development Manager at Tox Pressotechnik. "We can always offer the customer the optimum drive concept for the respective application - in the usual high quality."

The tried-and-tested pneumohydraulic Tox power packs and electromechanical Tox ElectricDrive drives are available in various designs and with a wide range of accessories. They can be installed in any position and, in most cases, do not require external tool guidance. "We cover the entire force range from 0.02 to 2,000 kN with both drive systems," says Ortmann. The robust pneumohydraulic drives can be optionally equipped with press-in monitoring, while the electromechanical version already has integrated process monitoring. "This gives the user 100% control over the pressing process and the quality of their product at all times," promises the Business Development Manager.
