6. Defects observed during installation. Solutions
As we've seen, the gas-assisted injection molding process has many advantages, but also disadvantages which can have dramatic consequences for the part and therefore for the processor. Indeed, committing to produce a part using this process, and then having to offer the customer an alternative solution because technical problems have not been solved, can be commercially penalizing for the future.
A non-exhaustive list of faults that can be observed when using this process, with a suggested solution or remedy, is given in this paragraph.

Material front perforation
Material front perforation is caused by insufficient material injection. To remedy this, simply increase the quantity of polymer injected until a stable process is achieved. In the set-up phase, it is preferable to start by eliminating...

Patents
It wasn't until 2010 that the legal situation reached an epilogue: the legal wrangling that had disrupted the development of the gas-assisted injection process came to an end the day the feeder patent fell into the public domain. But the damage had been done, and many processors had become discouraged by the difficulties.
