About Us
Ma'anshan ONA Intelligent Equipment Co., Ltd. is a foundry specializing in the manufacture of wear-resistant parts for crushers. Its main products include jaw plates, mantle and bowl liner, hammers, impact plates, feed cone, check plate and more. We also provide customers with almost a complete range of accessories, such as adjusting ring assemblies, head assemblies, bowl assemblies, main frame assemblies, tramp release cylinder assemblies etc. Founded in 2010, Aona covers an area of over 35,000 square meters and boasts modern standard workshops and professional production lines. We currently have over 200 employees and a professional team. We mainly produce crusher parts suit for brands such as Metso, Barmac, Sandvik, Symons, Telsmith, Terex, and Trio. (Please contact us for details if you have other needs.) As an OEM manufacturer certified by ISO9001 and ISO45001 quality systems, we strictly adhere to the principles of "drawing-based production, standardized control, and traceable delivery" to ensure that every product meets or exceeds the original manufacturer's technical standards. From material selection and heat treatment optimization to CNC precision machining, we have established a closed-loop quality management system for the entire process, and achieved full quality control through methods such as spectral analysis, coordinate measuring machine (CMM) testing, and non-destructive testing.
High Manganese Casting
High manganese steel castings are made of high-quality high manganese steel (Mn13cr2, Mn18r2 and Mn22cr2). After water toughening treatment, they have high strength, high toughness and excellent work hardening characteristics. Their service life can be several times that of ordinary steel, which significantly reduces the cost of crushing large materials and makes them an ideal choice for wear-resistant parts in mining.
High Chrome Casting
High-chromium steel castings are made from high-quality high-chromium alloys (Cr15, Cr20, Cr26, etc.). After precision heat treatment, they achieve high hardness, high wear resistance, and good corrosion resistance. The wear surface can remain smooth for a long time, significantly reducing equipment maintenance frequency and production energy consumption. Their wear resistance is many times that of ordinary steel.
Embedded alloys
Embedded alloy technology involves precisely embedding high-hardness wear-resistant alloys (such as tungsten carbide, cemented carbide, etc.) into key wear-prone areas of the base material (usually high-manganese steel or high-chromium steel) through a special process, forming a composite structure that combines rigidity and flexibility. This technology is widely used in wear-resistant parts in the mining, cement, and metallurgical industries, significantly extending part life by 1.5-1.8 times. Its benefits include reduced replacement time, increased production time, increased output, lower labor costs, reduced consumables such as cutting rings, fillers, locking bolt, wedges, square head bolts, and spherical nuts, and reduced risk of damage to the moving and fixed cones during liner removal.
Parts Production
ONA parts production utilizes an integrated process of precision casting, CNC machining, and heat treatment, strictly adhering to the ISO quality management system. From raw material spectral testing to finished product coordinate measuring machine (CMM), the entire process is digitally controlled to ensure dimensional accuracy and reliable performance. We support customized production based on drawings and batch delivery, providing material optimization and operating condition adaptation solutions, committed to extending spare parts life and reducing customers' overall maintenance costs.
Testing
ONA implements a fully digital testing process, Spectrum Analyzer, hardness testing, Magnetic Particle Flaw Detector, microstructure reporting, coordinate measuring machine (CMM), vibration measurement of rotor bearing housings, speed measurement, and non-destructive testing technologies to ensure that product composition, dimensions, and internal quality fully meet standards. Key components are further enhanced with metallographic analysis and working condition simulation wear testing. All data is uploaded to the system in real time, ensuring the reliability and long-term stability of each product with a zero-defect standard.
Packaging and Shipping
ONA follows standardized industrial packaging procedures, employing a triple-protection design based on product characteristics: precision-machined surfaces are sealed with vapor phase rust-preventive paper and PE stretch film; heavy-duty castings utilize a steel-wood composite frame with built-in cushioning materials. Each package is uniquely marked with the part number, batch number, and lifting identification. Leveraging the locational advantages of the Yangtze River Delta region, efficient shipping is achieved through core ports such as Shanghai and Ningbo, supporting full container load (FCL)/less than container load (LCL) sea freight, air freight, and multimodal transport. Real-time logistics tracking and customs clearance support are provided to ensure the safe and efficient arrival of goods at their global destinations.
On-site Guidance
ONA provides professional on-site technical guidance services, dispatching senior engineers to customer production sites to provide full support for equipment installation, commissioning, and maintenance. Engineers will guide standardized installation and torque standards based on actual operating conditions, demonstrate key points of preventative maintenance, and assist in developing personalized maintenance plans. Through on-site data collection and operating condition analysis, equipment operating parameters can be further optimized, improving production efficiency and safety levels.
Our Customers
ONA's customers are located in many countries and regions around the world. ONA's business covers approximately 50 countries globally, involving more than 100 ethnic groups. Our customers include various mining operators, aggregate processing plants, independent contractors, and equipment maintenance service providers worldwide, from large quarries in North America to medium-sized ore processing centers in Southeast Asia, from infrastructure projects in Africa to metal mines in South America. We provide suitable spare parts solutions for production sites of different sizes and operating conditions. Through localized service support and a rapid response mechanism, we have become a trusted partner for many front-line production units, helping them maintain continuous and stable equipment operation and effectively control maintenance costs.
