Detailed Manufacturing Process Flow

The production of high-quality pvc coated wire mesh is a multi-stage, precision-engineered process designed to ensure optimal performance and longevity. Each step is meticulously controlled to meet stringent industrial standards, such as ISO 9001 for quality management and relevant ASTM or EN standards for material properties and testing.

Key Stages of Production:

1. Wire Drawing: High-quality low-carbon steel wire rods, conforming to standards like ASTM A853 or EN 10218-2, are drawn through a series of dies to achieve the desired core wire diameter. This process increases tensile strength and refines the wire's surface, preparing it for subsequent stages.
2. Welding (or Weaving): For welded wire mesh, individual wires are precisely positioned and fused together at their intersections using automated resistance welding machines. This creates a strong, uniform grid structure with consistent mesh openings. For woven mesh, wires are interlaced to form the mesh pattern. This stage is critical for the structural integrity of the final pvc coated wire mesh product.
3. Cleaning and Pre-treatment: The raw mesh panels undergo thorough cleaning to remove impurities, oils, and scales. This is typically followed by a multi-stage pre-treatment process, including phosphating or hot-dip galvanization. Phosphating creates a chemical conversion coating that enhances adhesion of the PVC and provides an initial layer of corrosion protection. For superior corrosion resistance, hot-dip galvanization (per ASTM A123/A153) is often applied before PVC coating, providing a sacrificial zinc layer.
4. PVC Coating Application: This is the defining stage. The pre-treated mesh is heated to a specific temperature and then either dipped into a fluidized bed of PVC powder or subjected to electrostatic spraying with PVC powder. The heat causes the PVC powder to melt and uniformly adhere to the wire surface, encapsulating it completely. High-quality PVC resins are selected for their UV stability, chemical resistance, and flexibility, ensuring a long service life of typically 10-20 years, depending on environmental conditions.
5. Curing and Cooling: After coating, the mesh panels are moved to curing ovens where the PVC coating is polymerized and firmly bonded to the steel substrate. This thermal process ensures optimal adhesion, hardness, and durability of the coating. Subsequently, the mesh is gradually cooled to room temperature.
6. Quality Control and Finishing: Throughout the process, stringent quality control checks are performed. This includes visual inspection for coating uniformity, adhesion tests (e.g., cross-hatch test), thickness measurements of the PVC layer, and dimensional accuracy checks. Finished panels are then cut to size, bundled, and prepared for shipment.

The meticulous execution of these steps ensures that the final pvc coated wire mesh product offers exceptional resistance to corrosion, UV degradation, and physical abrasion, making it ideal for target industries such as petrochemical, metallurgy, water supply & drainage, agriculture, and security fencing where longevity and reliability are paramount. The inherent advantages include energy saving through reduced maintenance and replacement cycles, and superior corrosion resistance even in harsh environments.
