• PE/PP wood-plastic composite decking is produced by compound extrusion of fibers (wood flour, bamboo fiber, rice bran, etc.), inorganic materials (calcium powder, talc), and additives (lubricants, compatibilizers, coupling agents), etc.
•  
• Wood-plastic composite decking processing mainly involves one-step and two-step methods. The two-step process produces wood-plastic composites with a tight bond between the plastic and wood powder, making it a top choice for durable outdoor sun protection materials.
•  

• Two-step WPC decking making machine includes:  mixing raw materials according to a specific formula in a mixer to the required temperature, then cooling them to 40-50 °C in a cold mixer. The mixture is then granulated using a parrel twin extruder and poured into a conical twin-screw extruder for extrusion. It offers a degree of flexibility, is easy to operate, and requires relatively low overall technical skills from production staff, making it the most commonly used extrusion process in enterprises today.

Features of WPC Decking Making Machine

• EANS WPC decking making machine adopts advanced German extrusion technology, achieving high-efficiency extrusion and improving the working efficiency.
•  
• 1. Mixing: high speed mixing heats the mixture, melting and dispersing the additives into the resin, fiber, and inorganic materials. The more uniform the material dispersion, the more stable the production and product quality. After cold mixing at the set temperature, it is beneficial for production and color stability, removes moisture, and reduces material decomposition.
•  
• 2. Granulating: parallel twin-screw granulation is used, resulting in a stable screw structure. The combination of wood flour and plastic is more compact, maximizing the waterproof and moisture-proof properties of outdoor materials.
•  
• 3. Extrusion: use high-quality bimetallic screws and barrels, their segmented structure and internal full-alloy sintering technology reduce corrosion of the screw by wood flour and other plant fibers, extending the service life of both the screw and barrel. First- and second-generation wood-plastic composite materials can be produced upon request..
•  
• 4. Molding: made of high-quality alloy steel, improved extrusion efficiency, corrosion resistance, moisture resistance, insect resistance, high dimensional stability, and crack resistance.
•  
• 5. Embossing: emboss wood grain and other patterns onto the surface of the board in a one-to-one ratio, according to requirements.
•  
• EANS WPC decking production machines produce smooth-surfaced PE WPC decking flooring and significantly reduce labor and production costs, earning high praise from customers worldwide.
