Manufacturing Process of 1/2’ PVC electric protective pipe

Process Overview (Short Video):

Raw Material Mixing → Extrusion Molding → Sizing & Cooling → Automatic Cutting → Quality Inspection → Packaging & Storage

• Raw Material Mixing: Special grade, lead-free, UV-resistant polyvinyl chloride (PVC) resin is compounded with high-performance stabilizers, lubricants, and fire-retardant additives. This ensures exceptional mechanical properties and long-term weather resistance.
• Extrusion Molding: PVC blend is fed into a high-precision, twin-screw extruder. Controlled heating (165~185°C) achieves optimal plasticization. State-of-the-art dies form the precise 1/2’ internal bore diameter and wall thickness.
• Sizing & Cooling: The extrudate is passed through vacuum sizing calibration tanks to tightly control dimensions, followed by water spray cooling to lock in mechanical strength.
• Automatic Cutting: High-speed fly-knife cutter guarantees length tolerance within ±2mm. Length is marked automatically for traceability.
• Quality Inspection: Each batch undergoes hydrostatic pressure test (3.2MPa, ISO 4422), impact resistance, flame retardancy (UL94 V-0), and dimension checks as per ANSI C80.3.
• Packaging & Storage: Bundled in stacks, each pipe labeled with QR codes for batch tracking, ready for shipment.
