How does resin flow during molding affect fiber orientation in WPC flower boxes?

The molding process of Wood-Plastic Composite (WPC) flower boxes involves the flow of resin, which significantly impacts fiber orientation and, consequently, the mechanical properties of the final product. During injection or compression molding, the resin's viscosity and flow direction determine how fibers align within the composite.

When resin flows smoothly and uniformly, fibers tend to align along the flow direction, enhancing tensile strength and structural integrity. However, turbulent or uneven resin flow can cause random fiber distribution, leading to weak spots or inconsistent performance. Factors like mold design, injection speed, and resin temperature play critical roles in controlling fiber orientation.

Optimizing resin flow ensures better fiber alignment, improving the durability and aesthetic quality of WPC flower boxes. Understanding this relationship helps manufacturers produce high-performance, long-lasting composite products.
