PPS Equipment Requirements
Problem Phenomenon
Ordinary '2079851475616104452 machines have many problems processing PPS.
Cause Analysis
PPS processing temperature is as high as 300~340°C, and ordinary equipment has insufficient temperature control and temperature resistance capability; the screw and barrel need to be high-temperature resistant.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
①Select a high-temperature '2079851475616104452 machine; ②high-temperature resistant configuration of barrel and screw; ③sufficient heater band power; ④regularly calibrate the temperature control system.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PPS processing has rigid requirements for equipment; equipment capability is the premise of process stability.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
