Product Description


The PVC/UPVC Pipe Extrusion Line (Two-Cavity) is a high-efficiency industrial system designed for simultaneous production of dual PVC/UPVC pipes (up to Ø50mm) with precision and flexibility. Featuring a double-cavity mould and stainless steel spray calibration technology, this line eliminates cross-interference during adjustments, ensuring independent control over each pipe. Equipped with automated twin-tube haul-off (0-15m/min speed) and dual-control cutting systems, it maximizes productivity for applications in agricultural, construction, and industrial piping. With 2000N haul-off force and energy-efficient extruder output (120-240 kg/h), this two-cavity extrusion line is ideal for large-scale UPVC pipe manufacturing, offering seamless customization for specialty pipe designs.
