The gas generated during the molding process cannot escape and is compressed, causing the resin surface to heat and burn, which has a serious impact on continuous molding
.

In order to prevent uneven heat conduction in the injection molding machine barrel, the test results show that the use of an injection molding machine that is too large relative to the molded product should be avoided, the barrel temperature should be reduced, and the use of mold contact molding should be avoided to prevent heat loss from the mold
.

The GIMIM method also found the reason for the clogging of the pores, that is, the complex relationship between the volume of low-boiling and high-boiling substances and the total volume of substances in the decomposed gas
.

Finally, the GIMIM test method can also verify the purging process
