Aotian special-shaped stepped shafts are processed from high-quality cold heading fine wire, widely used in automotive, motorcycle and engineering machinery. Non-standard stepped structures can be customized per drawings or samples with precise tolerance control for each step dimension. The parts feature stable strength and excellent fatigue resistance to meet dynamic load requirements. Sampling and mass production are available, with cold heading steel grades including SWCH, 10B21 and SCM420 optional.
Quality Control
We have advanced inspection equipments so that to carry things out strictly according to the IQC,IPQC and OQC process. Also, our technical staff will record all data of mechanical properties for the finished wire and make quality guarantee certificate to customers. That's our commitment to the quality of our products.
We adopt the high purity nitrogen protection method, which can do the quick heat conduction,even heating and high productivity .After annealing, the hardness and tensile strength are steady,organization spheroidizing rate is high and grain size is uniform and without oxidation and decarburization,the surface of wire is smooth.
We use the phosphoric acid and soap lubricant from Taiwan. In the production line, we use the timer to control the soaking time of each pharmaceutical pool.
