PTFE Thermal Stability Resin
Problem Phenomenon
PTFE products have unstable performance after sintering, traced to resin thermal stability differences, batch number management missing.
Cause Analysis
Different batch numbers of resin have thermal stability differences; mixing causes product quality fluctuation; resin with poor thermal stability causes sintering defects; supplier quality differences.; When troubleshooting on site, verify item by item according to this mechanism, avoiding blind machine adjustment based only on experience
Solution
①Select resin with good thermal stability; ②Use the same batch number; ③Supplier quality assessment; ④Incoming material thermal stability inspection.; After adjustment, continuously sample to verify the effect, confirm stability before resuming mass production
Key Takeaway
PTFE resin thermal stability is the foundation of sintering quality; batch number management is a simple and effective control; incoming inspection prevents source fluctuation.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
