  Real-World Solutions: Case Studies in Plastic Recycling
  Hao Chuanhua shares success stories highlighting their product efficacy:
  1. Large-Scale Plastic Recycler
  A challenge: Inconsistent plasticizing and low output during film pelletizing, limiting recycled pellet quality.
  Avian’s solution: Custom single-screw design with specialized flight geometry and optimized L/D ratio.
  Result: 30% higher output, superior pellets entering high-end markets, boosting profitability and competitiveness.

  3. Recycled Plastic Pipe Producer
  A challenge: Internal bubbles and rough surfaces in pipes, failing national standards.
  Avian’s solution: Screw optimized for degassing and compression ratio.
  Result: Fewer bubbles, smoother surfaces, compliant quality, elevated brand reputation, and market share growth.

  Through quality and service excellence, Zhejiang Avian has earned global trust. Hao affirms their commitment: "We’ll continue innovating with customer focus, driving progress in the plastic machinery industry."
