ABS weld line strength 20-40%
Problem Phenomenon
ABS weld line strength is only 20-40% of the bulk, multiple gates and hole positions, mold temperature and gate optimization.
Cause Analysis
ABS weld line two melt fronts converge; strength 20-40% lower than nominal; multiple gates and hole positions; increasing mold temperature improves; gate position; venting management.
Solution
①Increase mold temperature to 75-80℃; ②gate position optimization; ③convergence temperature; ④venting management; ⑤strength test.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
The 20-40% strength retention of ABS weld line is a design constraint; mold temperature and gate are the main countermeasures; testing ensures structural safety.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
