In the production process of die-casting technology, injection pressure and speed are two crucial process parameters. They are not only directly related to the fluidity and filling ability of the molten metal, but also have a profound impact on the quality of the entire Die-casting Civil Valve.
1. The importance of injection pressure
During the die casting process, injection pressure is an important parameter to ensure that the molten metal can fully fill the mold and form a complete product. The size of the injection pressure directly affects the fluidity and filling ability of the molten metal. When the injection pressure is too low, the molten metal may not completely fill the mold, resulting in defects such as shrinkage cavities and pores in the product; while the injection pressure is too high, the metal flow may be unstable and produce turbulence or turbulence, thus affecting the surface quality of the product. and internal structure.
2. Influence of injection speed
Injection speed is also a factor that cannot be ignored in die casting technology. The speed of injection directly affects the flow state and time of molten metal in the mold. When the injection speed is too slow, the molten metal flows in the mold for too long, which may cause the metal temperature to drop and reduce fluidity, thereby affecting the filling ability and surface quality of the product; while the injection speed is too fast, the metal may not flow properly. Stable, causing problems such as splashing and oxidation, and may even damage the mold.
3. The specific impact of injection pressure and speed on the quality of Die-casting Civil Valve
Filling ability: Appropriate injection pressure and speed can ensure that the molten metal fully fills the mold and forms a complete and dense product structure. This is essential to improve the sealing and service life of the Die-casting Civil Valve.
Surface quality: Control of injection pressure and speed can also optimize the surface quality of the product. Appropriate injection pressure and speed can make the molten metal flow evenly in the mold, reduce the occurrence of surface defects, and improve the appearance quality of the product.
Internal Structure: Injection pressure and speed also affect the internal structure of the Die-casting Civil Valve. Excessive injection pressure and speed may cause unstable metal flow and produce internal stress or deformation; while appropriate injection pressure and speed can ensure the uniformity and stability of the internal structure of the product.
In die casting technology, injection pressure and speed are two crucial process parameters. They are directly related to the quality and production efficiency of Die-casting Civil Valve. By reasonably controlling the injection pressure and speed, we can ensure that the molten metal fully fills the mold, optimizes the surface quality of the product, and improves the stability of the internal structure, thereby manufacturing high-quality, high-performance Die-casting Civil Valve products.
