How do we guarantee quality?
Firstly, We ensure quality from the source
Our spring flat bar is from the top 1 steel material supplier in China.
Secondly, Advanced Heat Treatment Technology
We have been deeply engaged in the leaf spring industry for many years, accumulating extensive experience and building a professional team of highly skilled and seasoned engineers. In the field of heat treatment, we possess not only advanced technology but also rich practical experience, enabling us to strictly control every production process. This ensures the superior quality and reliable performance of our leaf springs, providing customers with products and services they can trust.
The heat treatment process of leaf springs is a critical step to enhance their strength, toughness, and fatigue life. It typically includes three main procedures: heating, quenching, and tempering. First, the leaf spring is heated to a specific austenitizing temperature (usually between 850°C and 950°C) to transform the internal structure of the steel into a uniform austenite structure. Next, rapid cooling (quenching) is performed, usually using oil as the cooling medium, to form a high-hardness martensite structure. Finally, tempering is carried out by heating the leaf spring to an appropriate temperature (such as 400°C-600°C) and holding it for a certain period, which helps relieve internal stress while improving toughness and fatigue resistance. Through a scientifically designed and well-executed heat treatment process, the leaf spring can achieve high strength while maintaining excellent elasticity and durability, meeting the demands of vehicles under complex working conditions.
Thirdly: Strict Quality Inspection
We adopt comprehensive and rigorous testing processes to ensure that the quality and performance of the leaf springs meet the standards.
Our products have passed ISO9001 international quality standard certification. We implement all-round quality control from raw materials to finished products. The quality inspection system tracks the whole process and matches the finished product extreme performance test to fully ensure product quality.
