ABS processing temperature gradient principle
Problem Phenomenon
[Problem phenomenon] The role of each ABS temperature zone unclear, blind adjustment
Cause Analysis
Rear zone prevents bridging, middle zone mainly plasticizes, front zone controls melt temperature, nozzle ensures flow; understanding the function of each zone enables precise adjustment; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
Solution
Understand each zone temperature by function; check the middle zone for poor plasticization; check the front zone and nozzle for flow problems; 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
Key Takeaway
Each ABS temperature zone has its own role, understand the function for precise adjustment; 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 subsequent similar problems
