This project is a WPC (Wood-Plastic Composite) production line developed for the Saudi Arabian market. The entire system is designed with full automation for batching, conveying, and mixing, enabling a continuous and stable production process from raw material feeding to final forming.
The production line is composed of four core functional modules:
Big Bag Unloading Station
The Big Bag Unloading Station is the starting point of the entire production line. It is used for unloading and handling bulk raw materials such as wood powder, PVC resin, and fillers in a controlled and dust-free environment.
Main Components:
- Big bag unloading frame
- Electric / pneumatic discharge device
- Anti-bridging vibration system
- Fully enclosed dust collection system
- Buffer hopper
Key Features:
- Fully sealed and dust-free operation
- Fast and efficient big bag unloading
- Prevents material bridging and agglomeration
- Suitable for high-dust working environments
Dosing & Recipe Batching System
This system serves as the “core brain” of the entire production line, ensuring precise proportioning and automatic batching of multiple raw materials.
Core Components:
- Loss-in-weight feeders
- Weighing hopper system
- PLC recipe control system
- Automatic recipe management unit
- Data logging and traceability module
Key Features:
- Multi-recipe switching (PVC / WPC / PE formulations)
- High-precision batching (±0.3%)
- Automatic recipe storage and recall
- Remote monitoring and data management
Function:
Ensures consistent raw material ratios for every batch, improving product stability and mechanical performance.
High-Speed Mixing System
This system is used to pre-mix wood powder, resin, and additives to achieve a uniform and stable material state before processing.
Main Equipment:
- SRL-Z hot & cold mixing unit
- Temperature control system
- Automatic discharge system
Key Features:
- High-speed shear mixing for excellent dispersion
- Hot and cold mixing integration for material stability
- Short mixing cycle with high efficiency
- Ideal for high-filler WPC formulations
Automatic Conveying System
This system connects the batching and mixing sections, enabling fully automated and continuous material transfer.
Equipment Includes:
- Vacuum loaders
- Chain conveyors
- Screw conveyors
- Intermediate storage hoppers
Key Features:
- Fully enclosed conveying to prevent dust and moisture
- Multi-point automatic switching
- Reduced manual labor requirements
- Stable and continuous material supply
WPC Extrusion Line System
The extrusion section is the final forming stage of the production line. It adopts a twin-screw extrusion system to process mixed WPC materials into decking, profiles, or panels.
This part is integrated as a stable and mature system to ensure continuous and reliable production performance.
Overall Line Advantages
1.Fully automated production process (feeding → batching → mixing → conveying → forming
2.Centralized PLC control with intelligent recipe management
High-precision dosing system (±0.3%)
3.Designed for high-temperature and high-dust environments in Saudi Arabia
4.Compatible with WPC / PVC / PE materials
5.Customized capacity range: 500–3000 kg/h
Project Value
This production line significantly enhances local WPC manufacturing capability in Saudi Arabia, supporting the localization of eco-friendly building materials. It reduces dependence on imported composite materials and aligns with the growing demand for sustainable construction solutions.
