Injection molding machine
|
Mold plastic packing. |
Lower injection pressure and injection quantities.
|
|
Injection cylinder temperature is too high.
|
|
Injection pressure is maintained for too long.
|
Reduce screw forward time.
|
| Mold |
Porous mold surface scratches, or abrasions. |
Remove stains and polished surfaces of the mold.
|
|
Mold angle is insufficient.
|
Using every edge is 0.5 degrees minimum angle (angle larger, goes against the easier, faster operation).
|
|
Poor collapse designed
|
No frontal angle area guaranteed.
|
| Injection molded parts stuck high Polish mold surface. |
Using exhaust valve to remove pressure from highly polished surfaces of injection molded parts produced in vacuum.
|
|
Exhaled air, the secondary crest.
|
| Crest of inappropriate equipment. |
Increasing the number of crest or put on a different system.
