It is equipped with a complete set of intelligent production equipment such as CNC precision processing, automatic welding, professional heat treatment, and comprehensive performance testing, creating a closed-loop standardized production process. It has abandoned the extensive processing method and strictly controls each production process with refined techniques. Core three product advantages: 1. High-end materials: Strong and durable. All core components use national standard 27SiMn high-strength alloy structural steel, which has far superior tensile, compressive, impact, and deformation resistance compared to ordinary steel, suitable for high-pressure heavy-load, high-low temperature, dusty and humid harsh conditions, and is less likely to crack, deform, or rust, with a longer service life. 2. Imported seals: Eliminate leakage. All models are equipped with imported sealing components from well-known brands in Europe, Japan, and South Korea. They are resistant to aging, wear, and high temperatures, and are combined with precise assembly processes to completely solve the problems of oil leakage and oil seepage in the oil cylinder, ensuring stable operation and significantly reducing the later maintenance costs. 3. Strict quality inspection: Quality controllable. A four-level quality inspection system is implemented, from the non-destructive testing of raw materials entering the factory, self-inspection and mutual inspection of processes, to the 1.5 times rated pressure pressure retention test and all-item fatigue load detection of finished products, ensuring the traceability of quality throughout the process. It strictly adheres to industry standards and prevents the production of inferior products from leaving the factory. Main products & application fields: Main products: Engineering welding cylinders, multi-stage telescopic cylinders for dump trucks, pull-rod industrial cylinders, various non-standard customized hydraulic cylinders. Widely applicable to: Construction machinery, dump trucks, agricultural machinery, mining equipment, industrial automation, sanitation equipment, and other industries.
