What are the challenges in molding intricate designs into WPC outdoor flower pots?

Molding intricate designs into WPC (Wood-Plastic Composite) outdoor flower pots presents several challenges. First, WPC's composition—a blend of wood fibers and plastic—can limit fine detailing due to its fibrous texture. High-pressure injection molding is often required, but this may lead to uneven material flow, causing defects in complex patterns. Additionally, WPC's thermal sensitivity demands precise temperature control to avoid warping or cracking during cooling. The material's lower elasticity compared to pure plastic also restricts the depth and sharpness of engraved designs. Lastly, durability concerns arise, as intricate designs may weaken the structural integrity of the pots, impacting their longevity in outdoor conditions. Overcoming these challenges requires advanced molding techniques and careful material selection.
