What are the effects of resin flow properties during injection molding on WPC tree box quality?
The flow properties of resin during injection molding play a critical role in determining the quality of Wood-Plastic Composite (WPC) tree boxes. Key effects include:
1. Mold Filling Efficiency: Optimal resin viscosity ensures complete cavity filling, reducing defects like voids or short shots.
2. Surface Finish: Smooth flow minimizes weld lines and surface imperfections, enhancing aesthetics.
3. Structural Integrity: Balanced flow prevents uneven stress distribution, improving durability.
4. Material Distribution: Consistent flow avoids fiber segregation in WPCs, maintaining uniform strength.
5. Cycle Time: Low-viscosity resins may shorten molding cycles but risk flash formation.
Adjusting melt temperature, pressure, and additives can optimize flow for superior WPC tree box production.
