ABS glass fiber grade temperature
Problem Phenomenon
[Problem phenomenon] Glass fiber ABS follows the pure material process, floating fiber and insufficient filling coexist
Cause Analysis
Glass fiber grades have increased viscosity and require higher melt temperature and mold temperature to ensure wetting; screw speed reduced to protect fibers; wear requires wear-resistant configuration; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
Solution
Glass fiber grades take the upper limit of melt temperature and mold temperature; reduce speed; bimetallic barrel; 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
ABS glass fiber material takes temperature upper limit and reduced speed, equipment wear-resistant; 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
