In 2025, Handern's hollow sheet production lines were fully upgraded to the 5th generation, integrating intelligent control, data visualization, and mobile APP binding for IoT-enabled upgrades. As the global pioneer of one-step hollow sheet production lines, the company has added phosphogypsum hollow sheet production lines with a filling ratio increased to 70%, positioning itself as a complete set provider and one-stop solution supplier for environmentally friendly moisture-proof hollow sheet packaging box production lines. 

It has pioneered the green application of industrial solid waste phosphogypsum, delivering China's first complete one-step hollow sheet production line to Guizhou Phosphate Chemical Group in March 2024. 

As China's top provider of dry-process lithium battery separator production equipment and the only domestic enterprise capable of delivering complete production lines, it serves leading downstream clients such as BYD. In December 2023, it delivered China's first semi-solid electrolyte separator (gel polymer electrolyte separator) production line to a client.
