Suzhou Jiopeng intelligent to introduce to you: plastic mold test several major problems

First, the main runner sticky mold

The solution and order of the problem :1 polishing the main runner →2 nozzle and mold center coincide →3 Reduce the mold temperature 4 Shorten the injection time →5 add cold time 1 6 Check the nozzle adding ring →7 Polishing mold surface → 8 Check whether the data is polluted.

Second, it is difficult to release plastic parts

The method and order to solve the problem :1 reduce the injection pressure →2 shorten the injection time →3 increase the cooling time →4 Reduce the mold temperature →5 Polish the mold surface →6 increase the release inclination →7 reduce the gap at the insert

Third, the dimensional stability is poor

The solution and order of the problem :1 change the cylinder temperature →2 add the injection time →3 increase the injection pressure →4 Change the screw back pressure →5 increase the mold temperature →6 decrease the mold temperature →7 adjust the feed quantity →8 reduce the return proportion

Fourth, the appearance of ripples

The solution and order of the problem :1 adjust the amount of feed →2 increase the mold temperature →3 add injection time →4 increase the injection pressure →5 improve the material temperature →6 increase the injection speed →7 Add the size of the runner and gate

5. Warping and deformation of plastic parts

Solution and order :1 reduce the mold →2 reduce the material temperature →3 add cooling time →4 reduce the injection speed →5 reduce the injection pressure →6 add the screw back pressure →7 Shorten the injection time
