1. Brief description of metal wire mesh frame
The metal wire mesh frame uses iron wire, steel wire, stainless steel wire, etc. as the main raw materials, and is processed through a specific process into a mesh frame with a certain aperture, shape and load-bearing capacity.
Core function: Mainly plays the role of support, isolation, protection or load-bearing, such as steel mesh in buildings, fence frames for breeding, protective mesh covers in equipment, etc.
Common types: According to the forming process, it can be divided into welded mesh frame (such as welded mesh) and woven mesh frame (such as chain link mesh frame); according to the material, it can be divided into iron wire mesh frame, stainless steel wire mesh frame, galvanized wire mesh frame, etc.
2. Process flow and characteristics
1. Process flow (taking welded wire mesh frame as an example)
Raw material preparation: Select metal wires of corresponding specifications (such as iron wire with a diameter of 2-6mm), perform rust removal and straightening treatments to ensure that the wire surface is smooth and free of impurities to avoid affecting the quality of subsequent welding.
Welding forming: Use automated welding equipment (such as a welding machine) to arrange the straightened wires crosswise at preset intervals, and weld and fix them point by point or row by row to form a mesh structure. Some high-precision products will use spot welding technology to ensure that the solder joints are firm and have no obvious bulges.
Surface treatment: According to the needs of the usage scenario, anti-corrosion treatment is performed on the mesh. Common methods include hot-dip galvanizing (to improve corrosion resistance), plastic spraying (to increase aesthetics and rust resistance), and plastic dipping (suitable for outdoor heavy-duty protection).
Cutting and inspection: Cut the formed large mesh to the specified size according to customer requirements, and then check the mesh size, solder joint strength, surface treatment uniformity, etc., and reject unqualified products.
2. Core features of the process
Strong material adaptability: Metal wires of different materials and diameters can be used to meet various needs from light protection to heavy load-bearing.
The structure is flexible and controllable: the mesh size, frame size, and wire diameter can be adjusted according to the design to adapt to different application scenarios (for example, a breeding net needs small meshes to prevent escape, and a construction net needs large meshes to reduce weight).
High degree of automation: Mainstream production lines use fully automatic welding and straightening equipment. The average daily production capacity of a single line can reach thousands of square meters, significantly reducing labor costs and making product accuracy more stable.
Good quality controllability: The surface treatment process improves the weather resistance of the product and extends its service life; the finished product inspection process can effectively screen out defective products to ensure uniform batch quality.
