How does resin viscosity affect the molding process of WPC armchairs?

Resin viscosity plays a critical role in the molding process of Wood-Plastic Composite (WPC) armchairs, influencing both production efficiency and product quality. Higher viscosity resins require more pressure to flow into molds, potentially leading to incomplete filling or air entrapment, which can weaken the final structure. Conversely, low-viscosity resins flow more easily but may result in excessive material leakage or uneven curing.

The optimal viscosity ensures proper polymer flow, uniform distribution of wood fibers, and efficient curing, reducing defects like warping or weak spots. Manufacturers often adjust temperature and additives to achieve the ideal viscosity balance, ensuring durable and aesthetically pleasing WPC armchairs. Understanding this relationship helps optimize production and enhance the performance of composite furniture.
