Galvanised expanded mesh, The production process of galvanized metal mesh is a complex and delicate process aimed at ensuring the quality and performance of the final product. The following is a detailed explanation of the production process of galvanised expanded mesh.
The first step in producing galvanised expanded mesh is to select high-quality metal wires as raw materials. These wires typically have excellent mechanical properties and corrosion resistance to ensure the strength and stability of the final product. The selection of raw materials is crucial as it directly affects the smooth progress of subsequent processing and the final quality of the product.
After preparing the raw materials, the next step is the forming process of the metal mesh. This step usually involves two processes: weaving or welding:
Weaving process: suitable for occasions that require high breathability and transparency. By using precision weaving machinery, metal wires are woven according to predetermined grid sizes and shapes to form a metal mesh with a uniform grid structure.
Welding process: suitable for occasions that require higher strength and stability. By using advanced welding equipment and technology, metal wires are welded at intersections to form a sturdy metal mesh structure. During the welding process, it is necessary to strictly control parameters such as welding temperature, time, and pressure to ensure welding quality and grid flatness.
Galvanizing treatment is a key step in the production process of galvanised expanded mesh. This step is usually carried out in a dedicated galvanizing tank, where the zinc layer is uniformly attached to the surface of the metal mesh through electrochemical methods. The main purpose of galvanizing treatment is to improve the corrosion resistance of metal grids and extend their service life. The thickness and uniformity of the galvanized layer will directly affect the corrosion resistance and performance of the product. Therefore, it is necessary to strictly control the galvanizing process parameters during the production process to ensure that the quality of the galvanized layer meets relevant standards and requirements.
After the galvanizing process is completed, a series of post-processing and inspection work are also required. These tasks include cleaning, drying, trimming the edges of the mesh, removing burrs, etc. At the same time, quality inspection of galvanised expanded mesh is also required, including visual inspection, size measurement, corrosion resistance testing, etc. Only products that have undergone strict inspection and meet relevant standards and requirements can be sold after leaving the factory.
In summary, the production process of galvanised expanded mesh is a complex and delicate process, including multiple steps such as raw material preparation, metal mesh forming, galvanizing treatment, and post-treatment and inspection. Each stage requires strict control of process parameters and product quality to ensure that the quality and performance of the final product meet relevant standards and requirements.
