PRODUCTION PROCESS OF PVC ROOFING SHEET MAKING MACHINE

What is PVC roofing sheet

PVC roofing sheet is a lightweight roofing material made primarily from polyvinyl chloride (PVC) resin and various additives. It is manufactured by extrusion and forming processes to create flat, corrugated, or multi-layer roofing panels.

How Is PVC Roofing Sheet Manufactured?
1. Raw material mixing: PVC resin, plasticizer, stabilizer, and other raw materials are mixed according to a certain proportion to ensure uniform mixing of the raw materials.
2. PVC Extrusion: The prepared PVC compound is fed into the PVC roofing sheet extruder, where it is heated, plasticized, mixed, and conveyed forward. The screw design and processing temperature are controlled to achieve uniform plasticization and stable material flow.
3. Co-Extrusion for Multilayer Sheets: For multilayer PVC roofing sheets, two or more extruders feed different formulations into a co-extrusion die. This creates a multilayer structure, such as a UV-resistant surface layer combined with a structural core layer.
4. Sheet Forming: The extruded PVC melt passes through the forming system, where corrugated, trapezoidal, or other roofing profiles are shaped. The forming rollers determine the final profile, width, and surface shape of the sheet.
5. Corrugation Calibration Cooling: The formed sheet is cooled and calibrated to stabilize its dimensions and profile. Controlled cooling helps maintain consistent thickness, width, and dimensional stability.
6. Haul-Off: A haul-off unit continuously pulls the roofing sheet through the production line at a controlled speed. Stable hauling helps maintain uniform sheet dimensions and production speed.
7. Cutting: The continuous roofing sheet is cut into the required lengths by an automatic cutting machine. Cutting length can be adjusted according to customer requirements.
8. Stacking and Inspection: Finished PVC roofing sheets are collected and stacked automatically or manually. The sheets are then inspected for surface quality, thickness, width, profile accuracy, and overall appearance.

KEY FEATURES OF PVC ROOFING SHEET MAKING MACHINE FROM EANS

plastic extrusion expert

● Stable Extrusion Performance – The optimized extrusion system provides uniform plasticization and stable material flow, helping ensure consistent PVC roofing sheet quality.
● Multi layer co extrusion technology: A PVC roofing sheet machine is designed to produce multi-layer roofing sheets by combining different PVC formulations or materials into a single sheet structure. The co-extrusion process allows each layer to provide specific properties, such as strength, weather resistance, UV protection, color stability, or improved surface performance.
● High Production Efficiency – The PVC roofing sheet machine is designed for continuous operation, supporting high output while maintaining stable production performance.
● Precise Sheet Forming – Specialized forming and calibration systems help maintain accurate roofing sheet dimensions, thickness, and surface shape
● Flexible Product Options – The PVC roofing sheet making machine can produce corrugated, trapezoidal, flat, and multi-layer PVC roofing sheets with customized widths, thicknesses, and profiles.
● Excellent Sheet Quality – Controlled extrusion, forming, and cooling processes help produce roofing panels with a smooth surface, consistent thickness, and good dimensional stability.
● Energy-Efficient Operation – Optimized extruder components and temperature control help reduce energy consumption while maintaining efficient production.
● Easy Operation and Control – The centralized control system from EANS plastic roofing sheet making machine allows operators to conveniently monitor and adjust extrusion speed, temperature, forming, and cutting parameters.
● Complete Turnkey Solution – EANS can provide the complete UPVC roofing sheet making machine, including the extruder, co-extruder, die, forming unit, cooling system, haul-off, cutting machine, and other auxiliary equipment.
● Customized Production Solutions – EANS engineers can configure the PVC corrugated roofing sheet making machine according to the customer's raw material formulation, roofing sheet dimensions, production capacity, and roofing sheet requirements.

PVC ROOFING SHEET STRUCTURE

Single layer(standard roofing): A single-layer sheet consists mainly of a rigid PVC compound with additives. This structure is commonly used for lightweight roofing and wall cl./ adding.
Two layer(Weather-resistant roofing): ASA surface layer + PVC core layer
Three layer(Higher-performance roofing): ASA weather-resistant surface(Top layer) + PVC core layer (middle layer) + PVC based board (bottom layer)
Four layer(Premium roofing): ASA weather-resistant topcoat + Upper PVC substrate layer + Fiberglass mesh reinforcement layer (core) + Lower PVC bottom layer.

FAQ

What is PVC roofing sheet?

PVC roofing sheet (also called synthetic resin tiles) use PVC (polyvinyl chloride) as the main base material. High-quality products have a co-extruded ASA weather-resistant layer on the surface. They are a new type of polymer roofing tile formed by extrusion molding and are mostly used on pitched roofs to replace clay tiles and color steel tiles.

How many layers made from PVC roofing sheet making machine?

Stanard sheets: 2 layers ( Surface layer: ASA weather-resistant layer (0.15-0.3mm), UV resistant, fade-resistant, and aging-resistant. Core layer: PVC skeleton layer (2.0-3.0mm), PVC + stabilizers, toughening agents, and fillers, providing strength and toughness) High level roofing sheet:

Three-layer co-extrusion: ASA top layer + modified PVC core layer + PVC bottom layer (white glossy bottom layer)
Four-layer co-extrusion: ASA top layer + impact-resistant layer + light-shielding and heat-insulating layer + wear-resistant bottom layer. EANS Multi-extrusion compound PVC roofing sheet making machine build the products for high end market

How many labors required for PVC roofing sheet production?

A standard PVC roofing sheet production line typically requires 3–5 workers per shift, depending on the production capacity and level of automation. With automatic cutting, stacking, and packaging systems, labor requirements can be further reduced while improving production efficiency.

What's the delivery time of PVC roofing sheet machine?

Standard products typically require around 30–40 working days, while customized products may require a longer production time depending on the specific requirements.

What's the aftersale service?

EANS provides complete after-sales support, including installation and commissioning guidance, operator training, remote technical assistance, spare parts supply, maintenance guidance, and troubleshooting support. Our engineering team works closely with customers to ensure stable operation and efficient PVC roofing sheet production.
