Application: Automobile Manufacturing
In the automobile manufacturing industry, from the body stamping molding, precision machining of components to the entire vehicle painting process, a stable and clean air source as the production line of the “blood”, a direct impact on the quality of the product and production efficiency. ZAKF, a brand of Dongguan Jubei Compressor Fittings Co., Ltd, has launched a 50HP
Screw Air Compressor, which has become the key equipment for many automobile manufacturing companies to upgrade their production lines due to its excellent performance, intelligent control system and outstanding energy-saving performance.
In the automotive painting process, the quality of compressed air and the stability of air supply are extremely demanding. Before the introduction of ZAKF 50HP screw air compressor to an automobile manufacturing group in China, due to the large pulsation and impurities in the air supply from the compressor, particles and flow marks appeared on the paint surface, and the rework rate was as high as 18%, which seriously affected the production cycle and cost control.
3 Phase Air Compressor of ZAKF is equipped with a dual-stage filtration system to ensure that the output air is clean enough to meet the requirements of spraying. At the same time, the stable exhaust volume of 6.2m³/min (0.8MPa working condition) and the low pulsation characteristics allow the spraying robot to operate more accurately. Mr. Zhao, the technical director, said, “With the ZAKF compressor, the paint pass rate has increased to 95%, saving more than 200,000 yuan in rework costs every month, and the belt drive design effectively buffers the voltage fluctuations in the workshop grid, allowing stable operation even during peaks in electricity consumption.”
The large presses in the automotive stamping shop generate strong shock loads during operation, which challenges the durability of the air compressor. An automotive parts company in the U.S. used an inline compressor that was frequently shut down due to overloads, and the annual maintenance cost was as high as $500,000 per year. After replacing the ZAKF 50HP screw air compressor, the cushioning design of the belt drive absorbed the impact of the startup moment of the compressor, and the maintenance cycle of the mainframe was extended from 2,000 hours to 4,500 hours. The production manager exclaimed, “Now the equipment failure rate has dropped by 60%, production continuity has been greatly improved, annual output has been increased by 15%, and comprehensive energy costs have been reduced by 8%. The intelligent control system can also automatically adjust the air supply according to the rhythm of the stamping press, which really realizes energy saving and efficiency.”
