In the die-casting process of the clutch housing, is high-pressure spot cooling core needle technology used to improve the cooling effect of the hot spot? How does this technology affect the internal quality and air tightness of the 430 push clutch assembly?

In our company, an industry pioneer focusing on the design, development, manufacturing and sales of heavy-duty vehicle clutches, technological innovation and quality excellence are the dual engines that drive us forward. We are well aware that for the clutch, a key component of the automotive transmission system, its performance stability, durability and safety are directly related to the operating efficiency of the entire vehicle and the safety of passengers. Therefore, from the beginning of product design to the delivery and use of the final product, every link is integrated with our strict compliance with German technical standards and our unremitting pursuit of high-quality products.
In the die-casting process of the clutch housing, the cooling efficiency of the hot spot is one of the key factors that directly affect the quality of the casting. Traditional cooling methods often make it difficult to effectively control the hot spots inside complex structures, which can easily lead to stress concentration and uneven organization inside the casting, thereby affecting the mechanical properties and air tightness of the product. In order to overcome this problem, our company introduced high-pressure spot cooling core needle technology, which is an advanced cooling technology that integrates high-precision temperature control, fast response and precise positioning capabilities.
This technology sets specially designed core needles inside the mold. These core needles not only have extremely high heat resistance and wear resistance, but also can directly act on the hot zone inside the casting through high-pressure spray coolant according to the preset program during the die-casting process. This point-to-point cooling method greatly improves the cooling efficiency and shortens the cooling cycle. At the same time, it ensures the uniformity of cooling of various parts of the casting, and effectively avoids defects caused by local overheating or uneven cooling.
As a core component in the transmission system of heavy vehicles, the quality of the internal quality of the 430 push clutch assembly is directly related to the clutch's torque transmission capacity, wear resistance and service life. The application of high-pressure spot cooling core needle technology has significantly improved the internal quality of the 430 push clutch assembly in the following aspects:
Refined grain structure: The rapid and uniform cooling process promotes the refinement of metal grains inside the casting, reduces the formation of coarse grains, thereby improving the strength and toughness of the material, and making the clutch assembly show better durability and stability when subjected to high-load operation.
Reduced internal defects: By precisely controlling the cooling of the hot node, the generation of internal defects such as shrinkage cavities and shrinkage is effectively avoided, and the density and overall strength of the casting are improved, which is crucial to ensure the smooth engagement and separation of the clutch.
Optimized thermal stress distribution: Uniform cooling reduces the internal stress caused by uneven thermal expansion and contraction, avoids cracks and deformation caused by stress concentration, and ensures the dimensional stability and long-term reliability of the clutch assembly.
Air tightness is another important indicator in the performance evaluation of the clutch assembly, which is directly related to the sealing effect and oil leakage of the clutch. High-pressure spot cooling core needle technology significantly improves the air tightness of the 430 push clutch assembly through the following mechanisms:
Reducing porosity: Effective hot spot cooling reduces the pores and microcracks inside the casting, which are often the main channels for oil leakage. The reduction in porosity directly enhances the sealing ability of the clutch housing and reduces the risk of oil leakage.
Precisely control the size of the casting: Uniform cooling avoids dimensional deviations caused by thermal deformation, ensures the accuracy and assembly accuracy of the mating surfaces of the clutch assembly, and provides a basis for forming an effective sealing structure.
Improving material density: By refining the grains and optimizing the organization, the density of the material is improved, so that the clutch housing can better resist external pressure and oil penetration, and further enhances air tightness.
Since our company passed the IATF16949 quality management system certification in 2008, it has always strictly implemented quality control management in accordance with the system requirements, and the clutch assembly qualification rate has remained at a high level of ≥99.8%, which is inseparable from our continuous investment in technological innovation and the ultimate pursuit of production details. We have a professional testing center in the industry, equipped with advanced testing equipment from Germany, Switzerland, Italy and other countries, which provides us with strong technical support and quality assurance. The application of high-pressure spot cooling core needle technology is a microcosm of our technical strength and innovation ability. It not only improves the intrinsic quality of the product, but also demonstrates our deep understanding of customer needs and our unremitting pursuit of excellent quality.
The application of high-pressure spot cooling core needle technology in the clutch housing die-casting process not only significantly improves the internal quality and air tightness of the 430 push clutch assembly, but also vividly reflects our company's insistence on technological innovation and pursuit of quality excellence.
