I-Flow adopt advanced assembly line modeling technology, clean working environment and high production efficiency. After smelting molten steel undergoes strict chemical testing, it is cast into a sand mold. The processing equipment is advanced CNC machine tools and machine tools specially used for valves, with high processing precision and fast speed. The spraying adopts advanced assembly line electrostatic spraying, which is environmentally friendly and economical, with uniform thickness, good adhesion and good anti-corrosion performance. Each valve is tested for pressure and size to ensure quality. Each process link has professional inspectors to check the quality. There are also three coordinates, spectrometer, X-ray, etc, to ensure zero defects in the product.
