Application: Foundry equipment
In the foundry industry, from metal melting, molding to casting, every step of the process has strict requirements for the stability, cleanliness and continuity of compressed air. Whether driving large pneumatic equipment for mold opening and closing, sand compacting, or for automated spraying, dust removal system to provide power, stable and reliable air source is to protect the quality of castings, improve production efficiency is the key. ZAKF, a brand of Dongguan Jubei Compressor Parts Co., Ltd, has launched a 220HP
Screw Air Compressor, which has become the core equipment for many foundry enterprises to enhance their competitiveness by virtue of its excellent industrial-grade performance and stable performance.
Located in northern Italy, a large foundry with a hundred years of history, specializing in automotive engine blocks, heavy machinery parts and other high-precision castings. Previously, the air compressor used by the enterprise due to large fluctuations in air pressure, exhaust volume is not enough, resulting in uneven sand tightness, castings appeared pores, shrinkage and other defects, the product defective rate of up to 18%. At the same time, the frequent failure of the equipment makes the monthly downtime maintenance time of up to 25 hours, only the maintenance cost of more than 300,000 euros per year, the high energy consumption also makes the enterprise unbearable. Mr. Rossi, the production director, said helplessly: “The unstable gas source seriously affects our production rhythm and product quality, and in the highly competitive international market, we urgently need to find a reliable solution.”
With the introduction of the
ZAKF 220 HP screw air compressor, the factory's production situation has been radically improved. Its direct-drive industrial frequency motor with a high-precision 5:6 asymmetric tooth rotor achieves a stable, large-displacement compression of 32m³/min (0.9MPa), providing strong and stable power support for the casting line. The three-stage oil-air separation system and intelligent temperature control valve ensure that the compressed air output is fully compliant with ISO 8573-1 standard, and the defective rate of castings is reduced to 6%. The cast iron body and forced lubrication system, together with IP55 protection, enable the equipment to operate stably even in high-temperature and dusty foundries, and the maintenance cycle has been extended to 8,000 hours, which reduces downtime by 90% and saves more than 270,000 euros in annual maintenance costs. In addition, the full-load energy efficiency ratio reaches 5.2kW/m³/min, which is 35% more energy efficient than the previous piston machine, and reduces the annual electricity bill by about 150,000 euros. Mr. Rossi excitedly shares, "The 160 kw screw air compressor is very stable and has almost no failures, even during long periods of continuous production. Now our productivity has increased by 60%, the quality of our products is highly recognized by our customers, and we have seen a significant increase in orders from the high-end casting market!"
In addition to excellent performance, the ZAKF 220 HP screw air compressor simple and reliable direct-drive construction reduces maintenance costs by 30% compared to inverter models. The wide temperature adaptability of -15℃~50℃ allows the equipment to easily cope with the challenges of different seasons and environments. Dongguan Jiubei Compressor Parts Co., Ltd. provides global after-sales service, including a one-year warranty, sufficient stock of overseas original spare parts, as well as a team of professional engineers to quickly respond to the needs of installation and commissioning, regular maintenance and fault repair, for the stable production of foundry enterprises throughout the escort.
As a source manufacturer of screw air compressor, Dongguan JOABY Compressor Parts Co., Ltd. has 60,000 square meters of modernized production base, strictly control the quality of products. With an annual production capacity of 30,000 air compressors and 24,000 sets of after-treatment equipments, 3 independent overseas operating companies and 7 warehousing bases, we can realize 15-day delivery in Southeast Asia, the Middle East, Europe and the United States.
