MS Mold Gate Design
Problem Phenomenon
MS mold temperature 60-80℃, large sprue and runner design.
Cause Analysis
MS mold temperature 60-80℃; sprue diameter with internal taper best 5-7°; angle 7° for '2079851475616104452 products of 4mm or above; sprue diameter 8-10mm; gate length not exceeding 50mm.
Solution
①Mold temperature 60-80℃; ②sprue taper 5-7°; ③7° for thick parts; ④diameter 8-10mm; ⑤gate length ≤50mm.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
The large sprue and taper of MS mold design are standard; dimensional specifications ensure filling; management ensures quality.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
