In mid-June, news came from YZDS Auto Parts Group, an internationally renowned automobile spring stabilizer bar company: after using the HGJT special steel group's high-end spring steel to process automobile stabilizer bars for Volkswagen, after nearly 18 months of Tests and test reports show that the product surface quality, dimensional tolerances, hardenability, grain size, non-metallic inclusions and other indicators fully meet the customer's requirements for stabilizer bars, and at the same time meet the public's requirements for stabilizer bar fatigue life.
"This is another breakthrough after HGJT products are applied to key systems such as Volkswagen's power transmission, and further expanded into key assembly systems.
In 2017, when the HGJT sales staff dug into the high-end market, YZDS Auto Parts Group learned that YZDS was preparing for Volkswagen’s new model project, and initially locked the steel supplier to three competitive advanced special steel companies in China, HGJT Is one of them.
The steel used for automobile suspension is a safety component to ensure the safe driving of vehicles, and the quality of raw materials is very high. Moreover, it has to go through long-term fatigue tests, road tests and other processes, with long cycles and great difficulty.
Thanks to the full technical exchange between the three parties, the progress of Volkswagen's new model project continues to accelerate. In 2017, HGJT delivered qualified steel samples three times. In March 2018, the project was approved by the German public. Starting in 2019, HGJT will supply small quantities of Volkswagen projects.
From samples to mass production after PPAP approval, the quality control requirements of the production process have become higher and higher. The dimensional accuracy of the steel plate should be controlled within ±0.20mm.
In order to meet the needs of customers, HGJT has adopted a series of measures such as high-precision control of chemical composition, innovative production of special pass for reduced diameter, separate control of head and tail billets, and differentiation of rolling temperature.
In September 2019, Volkswagen's new model was officially launched for sale. It is equipped with a car stabilizer bar processed from HGJT high-performance spring steel, which brings a good driving experience to customers. The steel for stabilizer bar of HGJT passenger car has also achieved stable supply. goods.
