| Processing Cost | Medium (molding, sintering) | Higher (injection molding requires high-temp equipment) | – |

4.2 Life Cycle Cost Analysis

Although PEEK’s initial cost is 5 times that of PTFE, in the following scenarios the life cycle cost is lower:

High-load wear parts: PEEK service life is 10-50 times that of PTFE, significantly reducing replacement frequency

Precision structural parts: PEEK can be injection molded, suitable for mass production, with unit cost amortized

Maintenance-free design: PEEK’s wear resistance and fatigue performance can reduce maintenance costs

Case Study:
A chemical pump mechanical seal: PTFE seal ring price 500 RMB, service life 3 months; PEEK seal ring price 2500 RMB, service life 2 years. Life cycle cost: PTFE is 4000 RMB/year, PEEK is 1250 RMB/year, saving 69%.

4.3 Processing and Forming Comparison
