　　You will see a chain adjustment machine if walking inside further, which is for the correction of the chain verticality, pressure, gravity. The chain weaving and welding machine is automatic which can produce chain with a high consistency. The Fire welding machine is also automatic which makes a smooth surface of the chain by a small size of weaving process.

　　The chain making machine is used combining with the welding machine as well as different chain size with different machine, making a high quality lifting chain. A different clamping ways achieve tensile properties of various sizes of chain such as tensile strength, yield strength and so on.

　　Next I will introduce you the most important process which is quenching treatment. This process is aimed to transform the super cooled austenite to marten site or kainite for its structure. Tempering with different temperatures is next step in order to satisfy differing needs for different uses by improving the rigidity, hardness, wear resistance, fatigue strength and toughness of the chain.
