Manufacturing Principle Of WPC Wall Panels

(1) Material preparation

Wood fiber: Typically wood chips, wood flour, or other wood waste materials are used. These wood fibers can be waste products from the wood processing industry and are intended for recycling.

Thermoplastics: such as polyethylene (PE), polypropylene (PP), etc. Plastic is used to mix with wood fibers to form composite materials.

(2) Mix

Wood fibers and plastic are mixed in certain proportions. During the mixing process, additives such as preservatives, stabilizers, etc. are often added to improve the performance and durability of the composite.

(3) Processing

The mixed raw materials go through processing processes such as extrusion or molding, and are formed through high temperature and high pressure.

(4) Extrusion

The mixture is heated by an extruder, extruded into a plate shape, and cut into specified sizes through a molding die.

(5) Molding

The mixture is placed into a mold and hot-pressed under high pressure to shape and solidify.

(6) Surface treatment

The formed WPC wall panels may require surface treatment, such as grinding, polishing or spraying, to increase the appearance texture and protective layer.
