Application: Casting
In the casting industry, stable and reliable compressed air is indispensable for every step of the process, from sand mold making, metal melting to casting molding. Whether it is to drive pneumatic equipment for mold cleaning, modeling and compacting, or to provide power for sand blasting and spraying process, high quality air source is the key element to ensure the quality of castings and improve production efficiency. Dongguan Jubei Compressor Accessories Co., Ltd. brand ZAKF introduced 120 HP
Screw Air Compressor, with high efficiency and stability, low maintenance costs and other significant advantages, to become the world's many foundry enterprises to enhance the competitiveness of the right hand.
Is a well-established foundry in Germany, which mainly produces high value-added castings such as automobile engine blocks and precision mechanical components. Previously, the enterprise used the air compressor due to large fluctuations in air pressure, frequent maintenance, resulting in uneven sand tightness, casting porosity, sand holes and other defects occur frequently, product defective rate of up to 17%. At the same time, equipment failure caused by the downtime problem, the average monthly delay in production time of 18 hours, resulting in huge economic losses. The factory manager said, “The unstable gas source seriously affects our production rhythm and product quality, and we urgently need a more reliable solution in the highly competitive European market.”
With the introduction of the ZAKF 120 HP screw air compressor, the factory's production situation has been greatly improved. The direct-drive structure of the IF motor combined with the high-efficiency screw mainframe provides a volumetric efficiency of over 90%, which is 28% more energy efficient than the previous machine and saves the company about 45,000 euros per year in electricity costs. The stable 0.8 - 1.0MPa air pressure output and three-stage filtration system ensure that the compressed air quality meets the ISO 8573-1 standard, and the defective rate of castings is reduced to 5%. The modular design and 6,000-hour maintenance intervals have reduced downtime by 90%. The plant manager is excited: "The 90 kw screw air compressor operates very reliably, the noise level is below 78dB, and the workshop environment is much more comfortable. Now our productivity has increased by 50%, our customer orders have increased significantly, and we are much more competitive in the high-end foundry market!"
In addition to its outstanding performance, the
ZAKF 120 HP screw air compressor robust cast iron body and its adaptability to a stable power grid enable it to operate consistently in 24-hour foundry production. Compared with inverter models, the lower initial investment cost and higher mechanical efficiency saves companies a lot of money and effort. In addition, Dongguan JOBE Compressor Parts Co., Ltd. provides a full range of internationalized after-sales service, including a one-year warranty, sufficient stock of overseas original spare parts, as well as a team of professional engineers covering the European region, which can quickly respond to the needs of equipment installation and commissioning, regular maintenance and fault repair for the stable production of foundry enterprises.
As the source manufacturer of screw air compressor, Dongguan JOABY Compressor Parts Co., Ltd. has strong production strength. 260 professional employees in the 60,000 square meters of modern production base, strict control of each production process to ensure stable and reliable product quality. With an annual output of about 30,000 air compressor and 24,000 sets of after treatment equipments, the company realizes 15-day delivery in Southeast Asia, the Middle East, and Europe with 3 independent operating companies and 7 warehousing bases overseas.
