A kind of multi-airway assisted plastic mould-injection process |
| abstract |
The invention discloses a kind of multi-airway assisted plastic mould-injection process, comprise the following steps：Step（1）Design of Plastic Mould；Step（2）The mould precooling stage；Step（3）Melt injection stage；Step（4）The multi-passage gas incidence control stage；Step（5）The local nitrogen charging stage；Step（6）Gas incidence ending phase；Step（7）The gas pumpback stage.This invention removes the internal stress existed inside injection molding product so that the quality of injection molding product is high, greatly improves the production efficiency and yield rate of mould. |
