Note a mouth to cover with shoot the mouth to do not have alignment; (2) .
Note a mouth to cover inside plastic and egregious ram; (3) .
Temperature ejaculation the mouth is too low; (4) .
Plastic noting the unfinished inside the mouth completely caky, especially the diameter is bigger note a mouth; (5) .
The garden dambered surface that notes a mouth to cover and the garden dambered surface that shoot the mouth cooperate undeserved, occurrence outfit is like " dried mushrooms " flow path. (6) .
Flow path pulls out not quite rake. 3, remedy a method (1) .
Will shoot afresh the mouth and note a mouth to cover alignment; (2) .
Reduce the pressure that note model; (3) .
Reduce screw forward time; (4) .
Raise temperature ejaculation the mouth or give with an independent temperature controller shoot the mouth to heat; (5) .
Increase cooling time, but better idea is to use have lesser note a mouth note a mouth to cover replace originally note a mouth to cover; (6) .
Correctional note a mouth to cover coordinate a side with what shoot the mouth; (7) .
Enlarge flow path appropriately pull out rake. Model warpage one, note model the feature of blemish notes model appearance and modular antrum likeness but the screwy version that is modular antrum appearance however. 2, the reason that appears possibly (1) .
Because note model,bending is inside have overmuch and in-house stress. (2) .
Mould fill rate is slow. (3) .
Inside modular antrum plastic inadequacy. (4) .
Too low or plastic temperature is abhorrent. (5) .
Note model too hot when the top goes out. (6) .
Refrigeration is not worth or move, fixed die temperature is abhorrent. (7) .
Note model the structure is unreasonable (if reinforcement is centered in one side, but apart is further) . 3, remedy a method (1) .
Reduce the pressure that note model; (2) .
Reduce screw forward time; (3) .
Increase periodic time (especially cooling time) ; From the mould inside (especially thicker note model) after the top goes out instantly immerge Wen Shuizhong (38oC) make note model cool slowly. (4) .
Raise the rate that note model; (5) .
Raise plastic temperature; (6) .
With cooling equipment; (7) .
Increase cooling time appropriately or improve cooling condition, assure to move as far as possible, fixed die model is lukewarm consistent; (8) .
