PS Product Gate Design
Fenómeno del problema
Stress concentration and cracking at the gate.
Análisis de la causa
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
Solución
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
Conclusión clave
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
