PPSU gate design
Problem Phenomenon
PPSU gate type and size; high-viscosity flow and appearance.
Cause Analysis
PPSU high-viscosity gate design; type selection; sufficient size; flow balance; appearance influence.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Gate type adaptation; ②size design; ③flow simulation; ④appearance evaluation; ⑤optimization verification.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PPSU gate is key to flow and appearance; design and simulation are equally important; verification ensures quality.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
