Improper matching of PP '2079851475616104452 machine
Fenómeno del problema
A small machine molding large parts, or the shot volume approaching the upper limit, makes product quality unstable.
Análisis de la causa
Excessive shot volume utilization makes plasticization and metering unstable; insufficient clamping force margin also easily causes flash.; during on-site investigation, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
Solución
①Control the shot volume within 20~80% of the machine's rated range; ②check the clamping force margin; ③change the machine when necessary; ④stabilize the process parameters.; after adjustment, continuously sample and verify the effect, and resume mass production after confirming stability
Conclusión clave
Machine matching is the premise of stable production; quality problems beyond the reasonable utilization range should not be endured by forcing machine adjustments.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
