PS Product Gate Design
Problembeschreibung
Stress concentration and cracking at the gate.
Ursachenanalyse
PS is sensitive to notches, and the gate mark becomes the starting point of fracture; improper gate form and trimming method aggravate the problem.; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
Lösung
①Optimize gate form and position; ②trim flat; ③avoid stressed areas; ④select submarine gates for appearance surfaces.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Wichtigste Erkenntnis
The gate is the weak link of PS products; attention should be paid to both design and post-processing.; 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 in the future
