What manufacturing processes are commonly used to produce resin-based WPC outdoor tree boxes?

Resin-based Wood-Plastic Composite (WPC) outdoor tree boxes are popular for their durability and eco-friendly properties. The most common manufacturing processes include:

1. Extrusion: This method involves melting resin and wood fibers, then forcing the mixture through a mold to create uniform shapes. It’s ideal for long, hollow structures like tree boxes.

2. Injection Molding: Suitable for intricate designs, this process injects molten WPC into molds under high pressure, ensuring precise dimensions and smooth finishes.

3. Compression Molding: Here, preheated WPC material is compressed into molds, resulting in high-density, sturdy products perfect for heavy-duty outdoor use.

4. Rotational Molding: Used for large, seamless designs, this technique rotates molds to evenly distribute the material, creating durable, weather-resistant tree boxes.

These processes ensure WPC tree boxes are lightweight, resistant to rot and insects, and ideal for landscaping projects.
