The production line employs a high-pressure water jet combined with fully automated integrated processes, integrating automatic feeding, ultrasonic cleaning, precision burr removal using high-pressure jets, multi-stage rinsing, air-jet dehydration, hot-air drying, vacuum drying, cooling, and automatic unloading into a single system. It comprehensively handles machining, die-casting, forging of component internal cavities, removal of burrs from flow channels and external surfaces, as well as cleaning of cutting chips, oil contaminants, and impurities, replacing traditional methods such as manual grinding and segmented cleaning, thereby enabling continuous mass production from raw material post-processing to finished products. Featuring a modular design, the line is suitable for large-scale continuous manufacturing and flexible model-switching production across diverse product categories, with wide applications in automotive components, aerospace parts, new energy die-castings, semiconductors, hydraulic valve housings, construction machinery shells, precision hardware, and related fields.
