The influence of the manufacturing process of zinc alloy-plated bathroom accessories on strength

The influence of the manufacturing process of zinc alloy-plated bathroom accessories on strength is a complex and delicate process involving multiple links and factors. These accessories, such as shower heads, faucets, etc., are not only required to be beautiful and durable, but also to have sufficient strength to withstand the pressure and wear in daily use.
As the base material of bathroom accessories, the physical and chemical properties of zinc alloy itself are crucial to the strength of the final product. High-quality zinc alloy materials should have good die-casting forming performance, with low material loss and high production efficiency. In addition, the proportion of each component in the alloy will also affect its strength and corrosion resistance. Therefore, in the material selection stage, the alloy composition must be strictly controlled to ensure the strength foundation of the substrate.
Pre-plating treatment is a key step to ensure good bonding between the coating and the substrate. During the die-casting process, a dense oxide layer is easily formed on the surface of the zinc alloy. If this oxide layer is not completely removed, it will seriously affect the bonding force and strength of the coating. Therefore, pre-plating treatment usually includes steps such as cleaning, grinding, degreasing, corrosion and activation to completely remove surface dirt and oxide layer and expose the base metal crystal structure. The refinement of these processing steps directly affects the adhesion and overall strength of the coating.
The electroplating process is a key process in forming the coating and has a direct impact on the strength of the coating. In zinc alloy electroplating, a layer of zinc alloy coating is deposited on the metal surface by electrolysis. In this process, process parameters such as temperature, current density, plating solution composition, pH value and deposition rate must be strictly controlled. For example, too high a temperature will cause coarse grains and uneven structure, affecting the strength and corrosion resistance of the coating; while too high a current density may cause cracks and reduce the overall strength of the coating. Therefore, reasonable process parameter settings are the key to ensuring the strength and quality of the coating.
