Q1: What raw materials can the WPC granulation machine process?

A1: It works with PP/PE recycled plastic (bottles, film, bags) and wood-based materials (sawdust, rice husks, wheat straw) with a wood powder content of 30-70%.

Additionally, the machine can also handle other organic fillers like bamboo powder, coconut shell powder, waste clothes, fiberglass or agricultural residues (e.g., corn stalks, peanut shells) with appropriate adjustments to processing parameters. This flexibility allows manufacturers to utilize local renewable resources, reducing raw material costs while supporting circular economy practices. The system is optimized to ensure uniform mixing and plasticization of diverse material combinations, maintaining consistent pellet quality even when using variable input materials.

For example, when processing waste clothese recycling plant, the machine’s screw configuration and heating temperature can be fine-tuned to accommodate the material’s higher fiber density, ensuring thorough melting and bonding with plastic components. Similarly, coconut shell powder—known for its hardness—benefits from the machine’s robust mixing chamber, which prevents particle agglomeration and ensures even distribution throughout the composite. This adaptability not only broadens the range of usable raw materials but also empowers producers to develop specialized WPC pellets tailored to specific applications, such as high-strength construction materials or weather-resistant outdoor products.
