Countermeasures to counteract the adhesion of molded products to the film during injection molding

Cause
1.Injection pressure or barrel temperature

2.Too much feed material

3.Too long advance time of the pump column

4.Unbalance of the feeding port in multiple writing,

5.There is a depressed part in the mold

6.Deep cylinder parts release vacuum problem

7. Mold opening time change

8.Improper finishing of mold surface

9. Mold core misalignment



Corresponding measures
1)Reduce injection pressure or high barrel temperature

2)Reduce feeding material　

3)Reduce the advancing time of the service station

4) Limit the flow of plastic, as close as possible to the main stream or single-written mold imbalance of each feed opening

5) Eliminate depressions, lighten or increase the release angle

6) Provide sufficient air escape channels

7)Maintain a fixed mold opening time, if necessary, a timer should be used

8)Lighten the surface of the mold writing

9)Adjust the mold center and lock it by using the withdrawal angle.
