PLA extrusion sheet uneven thickness
Fenómeno del problema
Extruded sheet thickness deviation.
Análisis de la causa
Uneven die lip gap or uneven temperature distribution; PLA melt elasticity affects discharge.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solución
① Fine-tune the die lip gap; ② balance die temperature; ③ stabilize extrusion output; ④ online thickness measurement.; 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
Sheet thickness relies on die lip and temperature control management.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
