The PVC Roof Tile Extrusion Line (also known as PVC/ASA/PMMA synthetic resin roof tile making machine) is a continuous, automated production system that converts PVC powder, calcium carbonate, stabilizers, and additives into finished corrugated, trapezoidal, or glazed roof tiles—optionally with a co-extruded ASA or PMMA weather-resistant cap layer.
A typical line consists of a high-speed mixer, screw loader, conical twin-screw extruder (commonly SJZ80/156, 280–550 kg/h), an optional single-screw co-extruder for ASA/PMMA, a coat-hanger T-die with distributor, embossing rollers, vacuum calibration table, corrugated/glazed-tile forming machine, haul-off, synchronous cutter, and automatic stacker, all governed by a central PLC with Siemens/ABB/Omron components. Single-layer, two-layer (PVC+ASA), three-layer (with foamed core), and four-layer structures are available.
Standard output covers tile widths of 650–1360 mm, thicknesses of 0.8–4 mm, and line speeds of 0.5–3 m/min, with capacity ranging from 300 to 700 kg/h depending on extruder size and layer configuration.
Finished PVC roof tiles feature lightweight structure, corrosion and UV resistance, thermal and sound insulation, fire retardancy, and asbestos-free safety. They are widely used for industrial workshops, warehouses, agricultural greenhouses, carports, pavilions, coastal/chemical plants, and residential roofing as a durable, low-maintenance alternative to clay, metal, or asbestos tiles
