In the face of environmental trends, how does Tiansheng achieve green upgrades in its phosphating process by applying low-zinc, nickel-free, or silane technologies?
Release Time : 2025-07-31
In the sophisticated chain of modern automotive manufacturing, component surface treatment technology has long transcended simple rust prevention, evolving into a core link crucial to product lifespan, performance reliability, and premium quality. The electrophoresis service phosphating process, a key link in this process, serves as the "invisible bridge" between the metal substrate and the final coating. It not only provides an ideal adhesion foundation for subsequent electrophoretic coating, but also builds a dense chemical conversion film at the microscopic level, imparting profound resistance to corrosion, fatigue, and environmental attack. Within the Chinese automotive supply chain, Tiansheng, a professional and renowned automotive parts manufacturer, relies on its deep understanding and continuous refinement of this process to consistently deliver its products to the production lines of top global OEMs such as BMW Brilliance, Volvo, SAIC Volkswagen, and SAIC General Motors, becoming an indispensable force behind high-end manufacturing.
Tiansheng's success is rooted in its unwavering commitment to the principle that "craftsmanship is quality." While the phosphating process may appear traditional, it is actually extremely sensitive to parameters such as temperature, concentration, time, pH, and impurity ion control. Any slight fluctuation can lead to coarse film crystals, reduced adhesion, or insufficient corrosion resistance. Tiansheng has introduced a fully automated pre-treatment production line, combined with online monitoring and a closed-loop control system, to ensure that the crystallinity, film weight, and uniformity of the phosphate coating on each batch of parts meet the stringent technical standards of the original equipment manufacturer (OEM) before entering the electrophoretic tank. This stability is the foundation for earning the long-term trust of high-end customers. The phosphate coating not only provides a "locking" micro-anchor structure for the electrophoretic paint, significantly improving coating adhesion, but also provides cathodic protection in the event of film damage, slowing the spread of corrosion on the substrate and significantly extending the service life of parts in complex road and climatic conditions.
The innovation of the electrophoresis service phosphating process lies not only in the precision of process control, but also in its forward-looking approach to green manufacturing and sustainable development. Traditional phosphating processes rely on heavy metal ions such as zinc, manganese, and nickel, generating phosphorus-containing wastewater, which is difficult to treat and poses significant environmental risks. Tiansheng actively invests in research and development, exploring and applying new environmentally friendly pre-treatment technologies such as low-zinc, nickel-free, and even silane/zirconization. These technologies significantly reduce the use and emissions of hazardous substances while maintaining or even exceeding the performance of traditional phosphating. Furthermore, its electrophoretic coating production line utilizes high-throw-power, low-VOC (volatile organic compound) cathodic electrophoretic paint, coupled with an efficient ultrafiltration (UF) recovery system, to maximize paint utilization and achieve zero wastewater discharge. This shift from compliance to leadership not only enables Tiansheng to meet the increasingly stringent environmental audits of OEMs but also sets a green benchmark within the supply chain.
Tiansheng's components demonstrate a deep understanding of "high-end brand consistency." Products supplied to BMW Brilliance, Volvo, SAIC Volkswagen, and SAIC GM must adhere to their respective brands' unique quality systems and global standards. By establishing laboratories and testing centers synchronized with OEMs, Tiansheng can accurately simulate the extreme tests that components may encounter throughout the vehicle's lifecycle, such as salt spray, thermal cycling, and stone impact, ensuring that its surface treatment performance withstands the most rigorous verification. This "end-to-begin" R&D approach ensures that Tiansheng's products are not just qualified parts, but integral to the high-quality experience of the entire vehicle. From engine bay brackets to underbody suspension components, the smoothness, color consistency, and long-term durability of their surface coatings silently convey the refinement and reliability expected of a high-end vehicle.
Even more thought-provoking is Tiansheng's exemplary role in promoting the upgrading of China's automotive parts industry. It demonstrates that local companies are fully capable of breaking through technological barriers and entering the core circle of the world's top supply chain. This is driven by continuous R&D investment, a rigorous quality management system, meticulous attention to detail, and a deep responsiveness to customer needs. Tiansheng is no longer simply a "OEM" or "supporting" company, but a trusted "technical partner" to OEMs, jointly addressing the new challenges brought about by lightweighting, electrification, and intelligent technology. For example, it provides more corrosion-resistant surface treatment solutions for battery pack housings in new energy vehicles, or develops specialized pre-treatment processes for lightweight alloy components.
It can be said that the electrophoresis service phosphating process, while a part of the manufacturing process, determines the depth of a component's "inner strength." Tiansheng, through meticulous dedication to this process, transforms individual metal parts into reliable components that withstand the test of time and the environment. It safeguards driving safety with microscopic phosphating crystals, embraces a sustainable future with green production processes, and supports its international brand reputation with stable quality output. In an era of striving for excellence, responsibility, and innovation, it is quietly but undeniably contributing to the high-end development of Made in China.
