PPSU high-temperature dimensional stability
Fenómeno del problema
PPSU high-temperature dimensional stability; thermal expansion and stress management.
Análisis de la causa
PPSU good dimensional stability; coefficient of linear expansion; high-temperature creep; stress release; application verification.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solución
①Design with thermal expansion data; ②high-temperature verification; ③stress management; ④long-term tracking.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
Conclusión clave
PPSU dimensional stability is the basis of precision applications; data-driven design; verification ensures long-term.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
