The secrets of high-quality manufacturers of leveling machines in machinery manufacturing in 2026

According to data from the “2025 White Paper on CNC Sheet Metal Uncoiling and Leveling Technology in the Hardware Products Industry”, the annual production capacity of the domestic sheet metal processing industry has exceeded 1.2 billion tons, of which the annual demand for precision leveling equipment in the machinery manufacturing field has increased by 18%.
However, the current industry generally faces three major pain points: traditional leveling equipment has insufficient accuracy and is difficult to adapt to intelligent production processes; the processing efficiency of multi-thickness and multi-material plates is low; and residual stress affects the quality of finished products in subsequent welding and coiling processes.
