PMMA Continuous Load Limit
Fenómeno del problema
PMMA structural parts creep and deform under long-term load, eventually failing by stress cracking
Análisis de la causa
PMMA continuous load should not exceed 600psi (about 4.1MPa) at 23℃; long-term action beyond this limit will cause stress cracking and eventual failure, and structural design often ignores this limit
Solución
①Check structural parts against the 600psi continuous load limit; ②enlarge the cross-section or change material for long-term load-bearing parts; ③regularly measure creep deformation; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability
Conclusión clave
600psi is the red line for PMMA continuous load; structural verification must follow this limit rather than short-term strength; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
