As an advanced pipe connection method, grooved pipe fittings can be either exposed or buried, with rigid joints and flexible joints.
Different forging methods have different processes. Among them, hot die forging has the longest process.
Regularly check the punch turntable and die mounting base of stamping parts to ensure the coaxial accuracy of upper and lower turntables.
The first is high voltage and high current density impulse method. In the early stage of anodizing, high voltage and high current impact are adopted to connect the "islands" which are separated by impurities.
