Aerospace Non-Destructive Inspection Technology

Hydraulic presses are crucial, expensive equipment in the ceramic and aluminum profiles industries. Over time, they inevitably face challenges such as frame deformation, pillar fractures, and hydraulic cylinder damage, all related to usage and maintenance."Enterprises are the main body of technological innovation, and only by continuously developing new processes, technologies, and products can they maintain an invincible position." Lin Yanmin, the factory director of Davi Factory, who has a keen insight into the market situation, told the reporter, "Due to the aging of the early imported brand presses like Xiti and莱斯at the ceramic factory, which have been in operation for many years, they have entered a major overhaul period. This requires replacing broken frames, pillars, and damaged hydraulic cylinders, which can weigh several to even dozens of tons. These parts are expensive and often out of stock. After completing customs clearance procedures, it takes at least half a year to obtain the imported original parts. Shutting down one hydraulic machine means the entire配套 production line is paralyzed. Davi Factory has hired authoritative experts to study the repair technology of hydraulic machines. Faced with the difficulties of disassembling and repairing medium and large hydraulic machines, and the need for large cranes to remove roofs for disassembly, which consumes a lot of funds and time, Davi has innovatively developed applicable technologies to address these issues, enabling on-site repairs, saving costs, and improving efficiency. For example, replacing a 3000-ton press pillar used to take over ten days and over 200,000 yuan in costs. However, with Davi's welding repair technology, it now takes only three days and significantly reduces repair costs. Davi also offers a one-year warranty service commitment, which is well-received by customers.

Davii Factory is hiring and training high-quality professional personnel for on-site services. We use magnetic particle inspection and dye penetrant testing equipment to detect hydraulic machine components for air holes, cracks, and other defects, and we also entrust authorized testing departments for metallographic analysis. This process restores severely deformed and fractured frames, pillars, and damaged, non-functional hydraulic cylinders to a like-new condition, earning on-site inspections and recognition from foreign brand hydraulic machine agents and parts suppliers. Due to their contributions, nearly a hundred malfunctioning and sick-running hydraulic machines have regained their value. Davii's business scope has also expanded from Guangdong's ceramics and aluminum profiles to similar industries in Sichuan, Henan, and other regions.
