Common processes include die-casting molding, forging process, etc. The die-casting process has high production efficiency and high dimensional accuracy, while the forging process makes the internal structure of the elbow dense and with higher strength.
Usually, it undergoes surface treatment processes such as polishing and electroplating, making the internal and external surfaces smooth without burrs, improving the appearance quality and reducing the resistance during fluid transportation.
