Production Process

1. Wire Rope Pre-treatment: Standard-compliant galvanized or bare steel wire rope is selected as the core material and undergoes rigorous surface cleaning to ensure removal of oil contamination and oxide layers, providing an optimal adhesion foundation for plastic coating.
2. Preheating: The cleaned steel wire rope passes through a preheating device, uniformly raising the temperature of the metal core. This enhances the flowability and adhesion of the subsequent molten plastic coating while preventing defects caused by temperature differences.
3. Extrusion Coating: Preheated wire rope passes vertically or horizontally through a cross-head extruder. Under precisely controlled temperature and pressure, molten PVC plastic is uniformly and continuously extruded onto the surface of the wire rope moving at a constant speed.
4. Cooling and Setting: The coated wire rope immediately enters segmented cooling tanks. The PVC layer solidifies gradually from the outer layer inward, ensuring a dense structure, uniform roundness, and preventing internal stress.
5. Post-Processing and Inspection: Ropes undergo length cutting, end sealing, or spooling as required. Finished products undergo multiple tests including coating thickness measurement, adhesion testing (e.g., cross-hatch adhesion test), electrical insulation testing, corrosion resistance testing, and visual inspection.

Characteristics of PVC-Coated Steel Wire Rope

• Superior Weather and Corrosion Resistance: The PVC coating effectively isolates the rope from air, moisture, salt spray, and weak acid/alkali media. It exhibits outstanding corrosion resistance in atmospheric, mine water, and freshwater environments. Outdoor use requires minimal maintenance, with a service life far exceeding that of standard steel wire ropes.
• Flexibility and Abrasion Resistance: The outer PVC coating enhances rope flexibility, enabling easy bending and forming without coating cracking or fatigue failure from repeated bending. Its smooth surface reduces friction wear, making it suitable for dynamic load applications.
• Excellent Insulation and Shock Absorption: The PVC plastic layer provides reliable electrical insulation protection, suitable for applications requiring insulation. The plastic layer also offers inherent cushioning and shock absorption properties.
• High Strength and Safety: Fully inherits the tensile strength and fatigue resistance of premium steel wire rope cores, ensuring load-bearing safety.
• Outstanding Cost-Effectiveness and Versatility: Compared to PE, TPU, or nylon coatings, PVC reduces costs by 30%-50% while accommodating most application scenarios.

Applications of PVC-Coated Steel Wire Rope

• Lifting, Transportation, and Equipment: Steel wire ropes for port cranes, construction hoists, and meat processing plant lifting equipment—clean and wear-resistant.
• Safety Protection: Safety ropes for aerial work, stadium perimeter netting, construction site safety nets, and mine cage guide ropes.
• Landscaping and Architecture: Guardrail ropes for park greenery, residential perimeter fencing, courtyards, and outdoor sunshade systems; framework for barrier netting.
• Agriculture and Livestock: Greenhouse framework, farm fencing, livestock lead ropes.
• Industrial Fastening and Bundling: Overhead cable traction ropes, pipe bundling and securing, machinery protective netting, shelf tier netting, lightweight equipment securing cables.
• Daily & Civil Use: Clotheslines, pet leashes, pet fencing, craft weaving, and tent guy ropes.

Weight of PVC-Coated Steel Wire Rope

Theoretical Weight Calculation Formula

Theoretical weight of PVC-coated steel wire rope = Weight of steel wire rope core + Weight of PVC coating. The specific formula is as follows:

1. Wire rope core weight (kg/m) = 0.00617 × d₁² (where d₁ is core diameter in mm);
2. PVC coating weight (kg/m) = 0.0092 × (d₂² – d₁²) (where d₂ is finished diameter in mm, PVC density assumed as 1.4 g/cm³);
3. Total finished product weight (kg/m) = 0.00617 × d₁² + 0.0092 × (d₂² – d₁²).
