What are the effects of resin moisture content on WPC armchair production?

The moisture content of resin plays a critical role in the production of Wood-Plastic Composite (WPC) armchairs, influencing both the manufacturing process and the final product quality. Excessive moisture in the resin can lead to poor bonding between wood fibers and plastic matrices, resulting in weakened structural integrity and reduced durability of the armchair. During extrusion or molding, high moisture levels may cause bubbling or surface defects, compromising aesthetics and functionality. Conversely, overly dry resin can make the composite brittle, increasing the risk of cracks during production or use. Manufacturers must carefully control resin moisture to ensure optimal mechanical properties, dimensional stability, and longevity of WPC armchairs. Proper drying and moisture testing protocols are essential to maintain consistent quality in WPC furniture production.
