Wood-plastic composites are manufactured by wpc manufacturer using a thorough mixture of heated plastic and ground wood particles. The manufacturing process includes extrusion (processing into the desired shape), injection molding, and thermoforming or compression molding. However, more modern manufacturing processes for wood-plastic composites include the production of additives such as colorants, lubricants and UV stabilizers. These additives help to ensure the end product is specific for its intended application.

A major constraint for WPC manufacturing is the plastic processing by wpc manufacturer condition which will involve pressure and melt temperature. This manufacture process could degrade the wood filler.

The wood to plastic ratio is another important factor to consider in the manufacturing process as the selected formula will go a long way to determine the material behaviour during and after the production process. The wood percentage will affect the Melt Flow Index (MFI), and the stiffness and strength of the material. Typically, the more wood content a composite has, the lower the MFI. Although up to 70% wood may be added to the composite to achieve stiffness and strength, this would affect the ductility of the final product.
