40 HP screw air compressor in injection molding machine industry

2025,06,26
 
Application: Injection Molding Machine
 
    In the highly competitive injection molding machine industry, from the production of precision electronic housings to the molding of large-scale plastic products, a stable and efficient air source is the key to ensure product quality and production efficiency. The 40HP Screw Air Compressor launched by ZAKF, a brand of Dongguan Jiubei Compressor Fittings Co., Ltd, has become the core equipment for many injection molding companies to optimize their production due to its excellent performance, intelligent control and significant cost advantage. 
 
    In the field of precision injection molding, the requirements for compressed air stability and cleanliness are almost demanding. An enterprise in China focuses on cell phone shell injection molding production. The air compressor used in the past had frequent fluctuations in air pressure, which led to air bubbles, dimensional deviations and other problems in injection molded parts, and the defective rate was as high as 15%. After the introduction of ZAKF 40HP screw air compressor, its exhaust volume is maintained at a stable 5m³/min (0.8MPa working condition), and the third-generation screw rotor technology has achieved a leading energy efficiency of less than 3.0kW/(m³/min), which is 7% energy saving compared with the previous equipment. Mr. Chen, the production supervisor, feedback: “After the new compressor was put into use, the product yield rate increased to 92%, saving more than 80,000 yuan per month in raw material loss, while the energy saving effect is significant, reducing the annual electricity bill by 12%.”

    For large scale plastic product manufacturers, equipment with large load impacts and long running time requires high durability and easy maintenance of air compressors. A plastic products company in China mainly produces plastic trays, and the load varies dramatically when the injection molding machine is in operation. The direct-connected air compressor used in the past often malfunctioned due to overload, and the average downtime for maintenance was as long as 20 hours per month. After replacing the ZAKF 40HP screw air compressor, the belt drive design effectively cushions the load impact and extends the service life of the main machine to more than 60,000 hours, while the maintenance cycle of the equipment is up to 5,000 hours. Mr. Li, the plant manager, is pleased to say, “Now the equipment runs much more stably, the number of production interruptions has been greatly reduced, monthly production has increased by 20%, and the overall maintenance cost has been reduced by 25%.” 
 
    In addition, the ZAKF 40HP screw air compressor is equipped with an intelligent control system, which brings a brand-new management experience to the injection molding company. "Hengxing Plastics deployed multiple ZAKF 40HP screw air compressors in the workshop, and through the intelligent control system, the company realized the parallel operation of multiple machines, automatically adjusting the number of running units according to the production demand, avoiding energy wastage; at the same time, the early warning function detects the potential problems in advance, reducing the risk of sudden shutdowns. Mr. Wang, Technical Director, shared, “The intelligent system makes our gas source management more flexible and efficient, reduces the equipment failure rate by 40%, and greatly improves the response speed of production scheduling.”
