How does resin melt flow index impact WPC armchair extrusion efficiency?
The resin melt flow index (MFI) plays a critical role in the extrusion efficiency of wood-plastic composite (WPC) armchairs. A higher MFI indicates lower viscosity, allowing the resin to flow more easily through the extruder, reducing energy consumption and improving production speed. Conversely, a lower MFI can lead to uneven flow, causing defects like warping or incomplete filling. Optimizing the MFI ensures consistent material distribution, enhancing the structural integrity and surface finish of WPC armchairs. Manufacturers must balance MFI with other factors like temperature and screw design to achieve optimal extrusion performance. Understanding this relationship is key to improving productivity and product quality in WPC furniture manufacturing.
