Driven by the "Dual Carbon" goals and new power system development, the energy storage battery industry is scaling to GWh-level capacity expansion. Emerging technologies such as large-capacity cells, long-duration storage, and grid-scale architectures are rapidly evolving — placing heightened demands on assembly efficiency, pressure consistency, sealing reliability, and long-cycle-life operation across cell formation, module assembly, battery rack integration, and container-level pack assembly. Conventional methods can no longer meet the industry's core requirements for high safety, low cost, and extended service life.
Leveraging high-precision, high-consistency, flexible, and intelligent product advantages across three core business lines — servo press-fitting, intelligent tightening, and automatic feeding — Lixing delivers one-stop assembly solutions from standalone equipment to fully integrated lines for the energy storage battery industry. Our solutions are widely applied in large-capacity cell stack pressing, module endplate pressing, battery rack body assembly, liquid cooling plate press-fitting, module fixing bolts, battery rack high-voltage connector tightening, busbar fastening, container housing bolts, PCS mounting bolts, as well as automated feeding of screws, insulation components, and seals. Covering every critical process from cell-to-module through to complete energy storage system integration, we help energy storage enterprises achieve large-scale, high-quality production — significantly enhancing system safety and full-lifecycle reliability while driving energy storage battery manufacturing toward intelligent, digital, high-quality development.
Energy-storage inverter power boards often use dense M3-M6 screws at 0.5-3.5 N·m, where PCB pads and substrates are highly sensitive to over-tightening and under-torque. Leetx intelligent tightening monitors torque and angle to maintain controlled, qualified tightening.

The top cover is the final sealing operation for an energy-storage inverter and determines IP protection and outdoor durability. Leetx torque-angle curve monitoring helps balance gasket compression and housing strength so residual torque meets IP54/IP67 requirements.
