IV. Selection Decision Tree (Key Path)

1. Regulations and Field Screening
   • Medical implants → PEEK OPTIMA® LT1/MT
   • Food contact → FDA/EU 10/2011 certified models
2. Environmental Condition Screening
   • Temperature > 240°C → Reinforced models (450GL30/150CA30)
   • Chemical exposure → HT™ or standard models for acid resistance
3. Functional Requirement Screening
   • Wear resistance → PEEK FC series
   • Electrical conductivity → Carbon fiber reinforced (150CA30)
4. Processing and Cost Optimization
   • Precision injection molding → High-flow 450G
   • Cost-sensitive → Hybrid solution (PEEK+PPS)

VI. Processing Technology Guide

1. Injection Molding
   • Melt temperature: 360-400°C
   • Mold temperature: ≥160°C (reduce internal stress)
   • Screw speed: ≤100 rpm (prevent degradation)
2. 3D Printing (FDM)
   • Printing temperature: 390-420°C
   • Heat bed temperature: 120-140°C
   • Post-processing: Annealing at 200°C for 2 hours (increase crystallinity to 35%)
3. Machining
   • Tools: Carbide or diamond-coated
   • Cutting speed: 100-200 m/min (dry cutting or with coolant)

VII. Cost Optimization Strategy

• Hybrid material design: Use PEEK in critical areas, PPS in non-load-bearing areas (cost ↓30%).
• Recycled material utilization: Regrind grade material (cost ↓40%, performance retention >90%).
• Design simplification: Uniform wall thickness (yield ↑ to 95%+).
