How To Make WPC Decking

What is WPC board?

WPC board（wood plastic composite board) refer to the use of polyethylene, polypropylene and polyvinyl chloride to replace the usual resin adhesives, mixed with more than 60% of wood powder, rice husks, straw and other waste plant fibers to form new wood materials, and then processed by plastic processing such as extrusion, molding, injection molding, etc. to produce boards or profiles. Mainly used in building materials, furniture, logistics packaging and other industries. The board formed by hot extrusion of plastic and wood powder in a certain proportion is called extruded wood-plastic composite board.

The main uses of wood-plastic composites is to replace solid wood in various fields, such as, WPC decking flooring board, WPC wall cladding, WPC louvers, WPC fencing board, etc.

What is  WPC board made of?

The WPC board has co extrusion board and non co extrusion, all sides has a co extrusion layer in co extrusion board, non co extrusion board lifetime is 10 years, co extrusion board lifetime is 15 to 20 years. By adding an co extruder mahcine, you can make both co extrusion board and non co extrusion board in same machine.

PE WPC Decking Making Machine

- The wood plastic extrusion process is initially granulated by a parallel twin-screw extruder and then extruded by a conical screw, which can make up for the difficulty in plasticization, poor aging resistance, poor creep resistance, poor color consistency and durability, and tensile strength.

- Adopt conical twin screw extruder(which use 38CrMoAL material -- high-wearing, high strength, high temperature resistance, corrosion resistance), It has good feeding performance, mixing and plasticizing performance, exhaust performance, extrusion stability and other characteristics. It has other advantages of ordinary twin-screw extruders and can achieve high output, high quality and high efficiency.

Advantages of PE WPC Decking Flooring Board Making Machine

- WPC profile production line is used to make outdoor WPC profile, such as, WPC decking, WPC fence, WPC wall cladding, WPC column, and so on.

- Extrusion molding is a method in which materials are continuously passed through a die in a flowing state by heating and pressurizing the extruder. By change the mold, the machine can make the WPC boards with different sections and sizes.

- By changing the screw and barrel, This machine can manufacture indoor WPC board, such as, WPC door profile, PVC louver panel, WPC fluted wall panel and so on.

- The surface of composite WPC board can be treated by online/offine wood grain embossing machine and sanding brushing machine, which can make wooden design on surface.

 How to test WPC Board Quality？

1. Test the anti-aging

- Test the anti-aging, Use strong light to see if WPC board changes color in certain time. High-quality WPC boards are UV-stable and have good colorability.

2. Test ash

- Carry out combustion tests on wood plastic panels in a laboratory environment and record relevant data during the combustion process(The more residue there is, the poorer the quality of the raw materials)

3. Bending properties

- In order to prevent the wood plastic board from cracking and breaking during use, it is necessary to test the toughness and bending performance of the wood plastic board. The commonly used test method is the bending test, that is, the wood plastic board is subjected to a bending test on a testing machine to test its bending resistance.
