HDPE/TPO/EVA Waterproofing Membrane Coating Production Line
Jiayuan Innovation
Jiayuan develops polymer waterproofing membrane production lines for manufacturers that need stable extrusion coating, precise tension control, continuous roll production, and flexible product configuration. The system is designed for HDPE, TPO, EVA, and other polymer waterproofing membranes used in roofing, underground engineering, tunnel construction, photovoltaic roofing, and building waterproofing projects.
With automated control, uniform coating performance, and customizable line design, Jiayuan helps customers improve production consistency, reduce material waste, and build a reliable manufacturing process for waterproofing rolls.
Multi-Polymer Capability
HDPE Membrane Production
TPO Roofing Extrusion
EVA Composite Coating
For EVA-based waterproofing products, Jiayuan provides reliable extrusion coating technology capable of handling thermoplastic materials efficiently. The line delivers uniform coating distribution and excellent bonding performance, making it suitable for infrastructure, civil engineering, and environmental protection projects requiring flexible waterproof membranes.
How the Waterproofing Membrane Coating Production Line Works
A complete waterproofing membrane coating production line usually includes material feeding, extrusion coating, laminating, cooling, traction, edge trimming, winding, and automatic cutting. The exact configuration depends on the membrane structure and final product use.
| Process Step | Function |
| Material Feeding | Feeds polymer materials, adhesive, film, or reinforcement layers into the production system |
| Extrusion Coating | Applies molten polymer or coating material onto the substrate with controlled thickness |
| Laminating | Combines film, adhesive layer, release film, or composite layer according to product design |
| Cooling and Shaping | Stabilizes the membrane surface and controls dimensional accuracy |
| Tension Control | Keeps the membrane flat and prevents wrinkles or stretching |
| Edge Guiding and Trimming | Ensures clean roll edges and accurate product width |
| Winding and Cutting | Produces neat finished rolls for storage, transport, and downstream use |
Advanced Design Features
Non-Stop Die Channel
Jiayuan's specially designed die flow channel enables continuous and uniform coating performance while supporting material switching and product adjustments without stopping the production line. This significantly reduces downtime, minimizes raw material waste, and improves overall production efficiency.
Smart PLC Winding
The line is equipped with a PLC touch-screen control system, automatic edge-guiding technology, precision winding units, and automated cutting functions. These intelligent controls ensure neat roll edges, accurate dimensions, and consistent winding quality throughout production.
Stable Coating Weight Control
A pressure-stable adhesive dispensing system helps maintain uniform coating weight across the membrane width. Combined with precision pumps, coating dies, and automatic control, the line supports stable coating consistency and improves finished membrane quality.
Application
Building Waterproofing Projects
HDPE, TPO, and EVA waterproofing membranes are widely used in roofing systems, basements, foundations, tunnels, underground corridors, and large-scale construction projects. Jiayuan’s waterproofing membrane coating production line helps manufacturers produce polymer waterproof rolls with stable coating quality, reliable bonding performance, and consistent roll appearance.
Photovoltaic Roofing Systems
TPO and other polymer waterproofing membranes are commonly used in exposed roofing and photovoltaic roofing projects. These applications require weather resistance, UV stability, dimensional accuracy, and long-term waterproofing performance. Jiayuan’s production line supports continuous membrane manufacturing for industrial roofs, logistics centers, warehouses, and solar energy facilities.
Tunnel and Civil Engineering
HDPE and EVA waterproofing membranes are suitable for tunnel construction, railway projects, subway systems, underground utility corridors, and other civil engineering applications. The production line helps manufacturers produce durable waterproofing rolls with stable thickness, puncture resistance, and dependable moisture protection.
Industrial Basements and Underground Structures
Industrial facilities, commercial buildings, storage centers, and underground structures require waterproofing systems that can resist long-term moisture exposure. Membranes produced with Jiayuan equipment can be used for basements, foundations, retaining walls, and buried structures where stable waterproofing performance is required.
Services We Provide
Process Consultation
Jiayuan helps customers evaluate membrane material, coating structure, production width, coating weight, and finished roll requirements before line configuration. This helps reduce equipment selection errors and ensures the production line is matched with real manufacturing goals.
Customized Line Configuration
Each waterproofing membrane coating production line can be configured according to HDPE, TPO, EVA, or other polymer membrane requirements. Jiayuan can adjust extrusion systems, coating units, laminating structure, cooling section, winding system, and automation level based on the customer’s product plan.
