430 Pull Clutch Assembly for FAW Jiefang Vehicles

In order to improve the corrosion resistance and wear resistance of the 430 pull clutch assembly for FAW Jiefang vehicles, are surface treatment technologies (such as sandblasting, electroplating, etc.) used? What are the specific details of these technologies?

In our company, we focus on the design, research and development, manufacturing and sales of heavy-duty vehicle clutches, and every step is deeply rooted in the unremitting pursuit of technical excellence and quality assurance. As a leader in the industry, we not only strictly follow German technical standards, but also integrate the concept of producing high-quality products into every innovation and practice, and are committed to providing the automotive industry with fine workmanship, high cost-effective and trustworthy products. In particular, for the 430 pull-type clutch assembly for FAW Jiefang vehicles, we have devoted great technology and enthusiasm, with the goal of improving its corrosion resistance and wear resistance, and adopted advanced surface treatment technology to ensure that the product still performs well in complex and changing driving environments.
In order to improve the corrosion resistance and wear resistance of the 430 pull clutch assembly, we carefully selected and implemented a variety of surface treatment technologies, including but not limited to sandblasting, electroplating and more advanced surface coating technologies. Each technology aims to change the microstructure and chemical composition of the material surface by physical or chemical means to achieve the purpose of enhancing performance.
1. Sandblasting
Sandblasting is the first key process we use. It mainly uses high-pressure air to spray fine abrasive particles (such as diamond, glass beads, etc.) at high speed onto the surface of the clutch assembly to remove surface dirt, oxide layer and tiny defects, while forming a certain degree of roughness, laying a good foundation for subsequent surface treatment. This step not only improves the adhesion of the material, but also creates favorable conditions for subsequent anti-corrosion and wear-resistant treatment. We strictly control the parameters of sandblasting, such as abrasive type, spray pressure, angle and time, to ensure the consistency and optimization of the treatment effect.
2. Electroplating technology
Electroplating is another core technology for us to improve the corrosion resistance and wear resistance of the clutch assembly. We use the nickel-chromium (Ni-Cr) composite electroplating process, which can form a uniform, dense and high-hardness coating on the surface of key clutch components. The nickel layer, as the bottom layer, provides good corrosion resistance and adhesion; while the chromium layer, as the surface layer, effectively resists the friction and wear that may be encountered during use with its extremely high hardness and wear resistance. During the electroplating process, we strictly control the composition, temperature, current density and electroplating time of the electroplating solution to ensure uniform coating thickness and stable quality, thereby maximizing the service life of the clutch.
3. Advanced surface coating technology
In addition to traditional sandblasting and electroplating technologies, we have also introduced more advanced surface coating technologies such as plasma spraying and physical vapor deposition (PVD). Plasma spraying uses a high-temperature and high-speed plasma arc to melt and spray powder materials onto the surface of the substrate to form a solid coating that is not only corrosion-resistant and wear-resistant, but also maintains stable performance under extreme temperature conditions. PVD technology uses physical methods to deposit metal or alloy vapor directly onto the surface of the part under a vacuum environment to form an extremely thin but extremely dense coating. This technology is particularly suitable for parts that require high precision and high surface finish, such as key friction surfaces in clutches.
When implementing the above surface treatment technology, we pay attention to every detail, from the selection of raw materials to every step of the process, we follow strict standards and processes. For example, before electroplating, all parts must undergo strict cleaning and activation treatment to remove impurities such as grease and moisture to ensure a good combination of the electroplated layer and the substrate. In the application of coating technology, we use advanced equipment to monitor the coating thickness, uniformity and porosity to ensure the coating quality is optimal.
The company's industry-leading professional testing center is equipped with a number of advanced testing equipment from Germany, Switzerland, Italy and other countries, such as X-ray fluorescence spectrometers, scanning electron microscopes, hardness testers, etc. These equipment provide us with precise quality control means. From the entry of raw materials to the delivery of finished products, every link is strictly tested to ensure that the performance indicators of the clutch assembly meet or even exceed customer expectations.
Since passing the IATF16949 quality management system certification in 2008, our company has always strictly followed the procedures and requirements of the system for quality control management, and the qualified rate of the clutch assembly has continued to remain at a high level of ≥99.8%. This is not only a recognition of our technical strength and management level, but also a fulfillment of our promise to every customer. We are well aware that technology is the core driving force for the progress of the industry, and quality is the foundation for winning the trust of the market. Therefore, we will continue to uphold the German technical standards and the concept of producing high-quality products, continue to explore and innovate, bring Ausde products into thousands of households, and provide consumers with valuable product competitive advantages and quality assurance. For the 430 pull clutch assembly equipped with FAW Jiefang vehicles, we have significantly improved its corrosion resistance and wear resistance by adopting a variety of surface treatment technologies including sandblasting, electroplating and advanced surface coating technology, ensuring the high performance and long life of the product. We firmly believe that through unremitting efforts and continuous technological innovation, we will bring more high-quality and reliable solutions to the automotive industry.
