How does the extrusion speed during manufacturing affect the surface finish of WPC tree boxes?

The extrusion speed during the manufacturing of WPC (Wood-Plastic Composite) tree boxes plays a critical role in determining the surface finish of the final product. A higher extrusion speed can lead to a smoother surface due to reduced friction and better material flow, but it may also cause inconsistencies if not properly controlled. Conversely, a slower speed allows for more precise shaping but might result in a rougher texture if the material cools unevenly.

Optimal extrusion speed ensures a balance between efficiency and quality, minimizing defects like warping or bubbles. Manufacturers must calibrate speed based on material composition and desired aesthetics to achieve a durable, visually appealing finish for WPC tree boxes. Proper control of this parameter enhances both functionality and longevity, making it a key factor in production.
