Forging aluminum blade high strength, good toughness, surface precision, so the fan efficiency is more high, the use of more reliable. Mainly used in coal mine, metallurgy, fan power, chemical, petroleum, subway, tunnel and other industries.. The annual production of various types of (leaf length: 200mm-1500mm) Forging Aluminum leaves a total of about 8000 pieces. The company has forged blank design, die design, manufacturing, forging, forging heat treatment, blade NC machining, blade natural frequency test, ultrasonic, permeability, leaf X optical non-destructive detection, analysis and calculation of the comprehensive ability of the blade strength.
