WPC Production Line

WPC Production Line for Profiles, Decking, and Fencing

Engineered for stable, high‑quality extrusion, this system produces wood–plastic composite boards and profiles for decking, fencing, cladding, and outdoor furniture. It covers dosing, extrusion, calibration, finishing, cutting, and stacking in a coordinated line.

Configurations support PE‑ or PVC‑based formulations, single or co‑extrusion cap layers, and both hollow and solid sections with reliable dimensions and weathering performance.

Why Choose These Lines

Proven engineering and certified quality: Built to CE requirements under ISO 9001:2015 with patented solutions and in‑house machining. Key components include Siemens control and ABB drives for reliable uptime.

Intelligent control and stable output: Monitors melt pressure, temperature, torque, and energy. Recipe management helps shorten start‑ups and improves color and texture consistency.

Fast delivery and export‑ready logistics: Modular builds and digital production allow standard configurations to ship within 60 days. Proximity to Shanghai and Ningbo ports supports swift export and installation.

Customization and lifecycle support: Receive tailored machine drawings, tooling proposals, factory testing with your materials, installation, training, spares, and remote assistance.

Configurations and Applications

Decking boards: Single or co‑extrusion with UV‑stable caps. Solid or hollow cores with in‑line embossing or sanding for durable, color‑consistent surfaces.

Fence and cladding profiles: Posts, rails, and facade elements with tight tolerances. Options from matte to woodgrain, plus protective caps for weather and stain resistance.

Door/window and furniture profiles: Trims, frames, and decorative or structural sections with screw holding and dimensional stability. Custom dies and calibration tables support complex cross‑sections.

Granulation and recycling: A WPC granulation line compounds wood flour, polymers, and additives into uniform pellets. Supports regrind reuse to control waste and material cost.

Core Equipment

Mixing and feeding: High‑speed mixers with gravimetric dosing for wood flour, polymer, color masterbatch, and additives. Dust control and optional drying stabilize premix quality.

Twin‑screw extruder and dies: Wear‑ and corrosion‑resistant screws ensure uniform compounding and efficient venting. Streamlined die channels improve pressure stability and shape fidelity.

Calibration, cooling, haul‑off: Vacuum calibration and multi‑stage spray cooling manage sizing and straightness. Servo‑driven haul‑off minimizes slip on textured profiles.

Cutting, stacking, surface treatment: No‑dust cutters or flying saws deliver clean edges at line speed. In‑line brushing, sanding, and embossing create natural textures; automated stacking improves handling.

Electrical and controls: Siemens PLC/HMI and ABB inverters enable recipe recall, diagnostics, and energy tracking. Open architecture integrates with MES/SCADA and remote support.

Performance Range

Output and line speed: Tuned to formulation and section size. Screw design and temperature profiles are optimized for stable melt and finish quality.

Dimensions and tolerances: Supports standard decking and fencing plus custom sections. Calibration layouts help limit warp and bow.

Energy and material efficiency: Efficient drives, insulation, and optimized heating reduce kWh/kg. Accurate dosing and closed‑loop control improve first‑pass yield.

Surface and color: Stable melt temperature and controlled traction help maintain embossing fidelity, color uniformity, and cap‑layer gloss.

Project Delivery

Assessment and blueprint: Receive a tailored plan for process flow, utilities, footprint, and 2D/3D tooling drawings.

Factory acceptance tests: Trials with your formulations validate surface, dimensions, and output before shipment.

On‑site commissioning and training: Installation, alignment, start‑up, and operator training with documented SOPs. Ongoing spares and remote diagnostics support uptime.

Options and Packages

Upgrades: Co‑extrusion for color streaking and UV‑stable caps; quick changeovers with recipe library; centralized dust/VOC management; remote monitoring with OEE dashboards.

Packages: Economy setup for startups; high‑output co‑extrusion for premium caps and throughput; flexible multi‑profile with quick‑change tooling sets.

Compliance, Shipping, and Warranty

Delivered with CE‑certified equipment, test reports, manuals, and safety interlocks and guarding. Standard lead time within 60 days with export crating and on‑site checklists. Warranty includes technical support and parts coverage.

FAQ

Q: Which polymers can the line process?

A: Common setups run PE‑ or PVC‑based WPC with wood flour and standard additives. Your formulation is verified during factory trials.

Q: Can I add a cap layer later?

A: Yes. Co‑extruders and cap tooling can be added as an upgrade when capacity or product mix grows.

Q: How do you control color consistency across shifts?

A: Recipe control, stable melt temperature, and controlled haul‑off maintain color and embossing. Gravimetric dosing supports repeatable results.
