PC/ABS glass fiber reinforced warpage
Problem Phenomenon
Directional warpage of reinforced parts.
Cause Analysis
Fiber orientation anisotropic shrinkage.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solution
①Optimize gate to uniform orientation; ②raise mold temperature; ③multi-point gates; ④low-warpage grade.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
The core of reinforced warpage is orientation management.; 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 later
