The sheet metal processing market demands high quality, and if the material is initially defective, it can hinder the operation of a highly automated production process. This results in an increase in production costs and limits the competitiveness of sheet metal processing companies. The application of the 4-high roller leveling machine can effectively reduce the rework and scrap rate. For example, the sheet metal parts produced by the laser processing factory are deformed after stamping, which is not conducive to the subsequent processing of process safety. After roll leveling, sheet metal parts can be welded quickly and precisely with minimal need for expensive rework.

Reduce man-hours by 90% per year, and data shows that by using a 4-high roller leveling machine, you can produce more sheet metal parts with stable quality. Increased machining efficiency means lower production costs, as shown in the case of a large supplier to a construction equipment manufacturer: With traditional leveling methods, such as leveling presses, it takes an average of 20 minutes for a worker to process each workpiece. Leveling by hammering and flame heating can take up to an hour even for an experienced mechanic.

In contrast, the 4-high roller leveling machine can complete the leveling of a large-sized workpiece in less than a minute. Overall, the use of a four-bar leveler can reduce the total man-hours for processing 60,000 workpieces per year to about 1,000 hours, which is only one-tenth of the time taken by traditional leveling methods. With the reduction of labor costs and the significant increase in production capacity, coupled with the most critical improvements to subsequent processes, the company's annual cost savings potential can reach millions of yuan.
