Tokyo, September 15, 2021/PRNewswire/ - Polyplastics Co.
, Ltd.
, the world's leading supplier of engineering thermoplastics, has discovered a variety of solutions that can effectively help processors reduce injection molding Gas combustion phenomenon that occurs in the process
.
The company uses an effective detection method to analyze this phenomenon and help develop preventive measures.

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
.
The company uses the above-mentioned detection methods to first detect the gas generated by energy loss during injection
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
.
The solution includes lowering the temperature of the barrel, and often using a rag and other items to wipe off the mold deposits that are slightly stuck to the exhaust port
Finally, the GIMIM test method can also verify the purging process
.
After multiple pieces of material are formed, there is currently no other method to verify the effect of the purging process except for visual confirmation
