Supplier's note

1. Technical Breakthroughs:

   • Material Upgrade: The Pro Model’s Duplex Stainless Steel offers 40% higher corrosion resistance than 304 steel.
   • Variable Pitch Design: Adjustable thread pitch in the Advanced Model improves material throughput by 25% in viscous polymers.
   • Surface Treatment: Nitriding in the Pro Model reduces wear by 30% in abrasive applications.

2. Optimal Version Selection:

   • Base Model: Ideal for SMEs handling standard plastics (e.g., PE/PP) in low-pressure extrusion.
   • Advanced Model: Suitable for medium-scale manufacturers requiring EPR compliance and processing engineering plastics (e.g., PEEK).
   • Pro Model: Designed for heavy industrial users needing high-pressure compounding (e.g., carbon-filled polymers) or compliance with dual EU EPR standards.

*Pro Model’s 300 bar capacity exceeds industry benchmarks by 20%, enabling extreme-pressure applications.
