The world's largest wood-plastic products production and application of the United States, its largest products are plank, the production process for the extrusion,Waterproof WPC wall panel can be first mixed into the middle of wood pellets, and then processed into products by extruder can also be cross-made Granulation, compounding (including devolatilization), extrusion profiles (sheet) in a device or a group of devices within the continuous completion.

The process of preparation of wood-plastic materials (including products) has a great impact on its performance, research shows that: improper processing will cause poor fiber dispersion and infiltration,outdoor wall panel and excessive compounding will make the fiber seriously damaged, both will reduce the plastic Mechanical Properties of Wood. In addition, to prevent excessive shear or high temperature to produce paste, charring and other issues, one-step continuous process if the devolatilization (main dehydration) poor will affect the continuity of the process, and products with bubbles and performance significantly reduced.cheap outdoor wpc floor At present, the main processing equipment for the twin-screw extruder, can be divided into the same direction parallel twin-screw extruder and cone-oriented twin-screw extruder.

With the parallel twin-screw extruder, plastic-wood processing industry, said the same direction to the parallel twin-screw extruder for high-speed, high energy consumption, "compound" type of equipment, usually modular screw, adjustable screw length to diameter ratio and configuration (Kneading block angle and the number of blocks,outdoor patio flooring different kneading block combination method), the flexibility to set the degassing port, can be directly processed wood powder or plant fiber, complete with wood powder mixed with molten resin and then continuous extrusion, wood powder drying and The resin melt is carried out separately, and therefore is often composed of a two-stage extruder.
