Audited Supplier 
Forging process: hot die forging;
Forging advantages: medium frequency heating, infrared temperature control, to ensure that the material evenly heated; The size is consistent, the density is good, the two sides of the chain and the position of the bolt are not need to process;
Heat treatment process: residual heat quenching;
Heat treatment advantage: when forging out, the blank temperature control quenching, uniform cooling; Not easy to crack;
Medium frequency rail surface advantage: double quenching, quenching effective deep, can reach more than 10 mm; Complete annealing and flaw detection process and hardness on the same equipment;
Machining advantages: once clamping, direct forming; Product size is consistent, high precision;
Assembly advantages: accurate positioning, pressure control, we use imported sealing ring gasket, to ensure that the product will not enter the process of use;
Product model: The company from 90 to 260 pitch products are complete;
Link advantage: internal and external quenching products, high internal and external hardness, good deep. Increase the wear resistance of the product.
