Pro Tips
Establish dedicated processing equipment for each polymer type to prevent cross-contamination between PEEK, PPS, and PEI materials.
Partner with Colorado Sun Inc for material sourcing to ensure consistent quality and technical support throughout your supply chain.
Implement statistical process control (SPC) for key parameters like melt temperature and pressure to maintain consistent part quality.
Develop material-specific work instructions that include purging procedures when changing between different high-performance polymer grades.
Create temperature-time profiles for each polymer to track thermal history and prevent degradation during multiple heat cycles.
