PCABS injection pressure
Problem Phenomenon
PC/ABS injection pressure 80-130MPa, high viscosity and complex structure requirements.
Cause Analysis
PC/ABS injection pressure 80-130MPa; high-viscosity melt; complex geometry filling; thin-wall requirements; balance between pressure and stress; mold strength.
Solution
①Injection pressure 80-130MPa; ②increase for complex structures; ③stress management; ④mold strength calculation; ⑤optimize and fix.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
The medium-high range of PCABS injection pressure is the filling guarantee; stress and mold safety are both important; fixing ensures stability.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
