What centrifugal casting techniques produce large-diameter PVC outdoor tree boxes?
Large-diameter PVC outdoor tree boxes are commonly produced using advanced centrifugal casting techniques to ensure strength, durability, and uniformity. The process involves rotating a mold at high speeds while molten PVC is poured inside, distributing the material evenly along the walls. This method is ideal for creating seamless, thick-walled tree boxes that resist cracking and weathering. Key techniques include horizontal centrifugal casting for consistent wall thickness and vertical casting for taller designs. Manufacturers often optimize parameters like rotational speed, temperature, and cooling rates to achieve high-quality results. These PVC tree boxes are widely used in urban landscaping due to their lightweight yet robust construction.
