you can try as the way below
1,increase the runner size and gate section size
2.increase mold temperature
3,decrease inject speed
4,increase the injection pressure
5,change gate location ,or change another gate type,probably also can add gate number,
6,check your dry time of the resin,is it enough?
7,is there any mold release agency left? clean the mold
8,try with increasing the melten temperature
9,reduce the cycle time,maybe it is too long time the resin kept in the barrel?
9,if all the action failed,please let you customer change the material or change the product structure.
it's a plus if you can show your detail or some pictures,then we can have a corresponding countermeasure to your issue, |
