How does resin flow front velocity during molding affect WPC flower box quality?
The resin flow front velocity during the molding process plays a critical role in determining the quality of Wood-Plastic Composite (WPC) flower boxes. A controlled and uniform flow ensures proper material distribution, minimizing voids and weak spots that could compromise structural integrity. If the velocity is too high, it may lead to excessive shear stress, causing surface defects like warping or uneven textures. Conversely, slow flow can result in incomplete filling, creating weak sections or air traps. Optimizing flow front velocity enhances mechanical strength, surface finish, and dimensional stability, making it essential for producing durable, high-quality WPC flower boxes. Proper mold design and process parameters are key to achieving the ideal flow characteristics.
