PP Cost Control
Fenómeno del problema
【Problem Phenomenon】PP cost pressure, cost reduction approach evaluation
Análisis de la causa
PP itself is a low-cost general-purpose material; cost reduction relies on: filling (talc/calcium carbonate), regrind, wall thickness optimization, high-efficiency molding; without sacrificing key performance; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
Solución
Select filling modification to reduce cost as needed; use regrind in compliance; uniform wall thickness to reduce material; after adjustment, take continuous samples 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
PP cost reduction relies on three optimizations: filling, regrind and wall thickness; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future
