4. Design features – constraints
Gas-assisted injection molding is just one of a number of injection processes, and should be considered first and foremost to meet a technical need. However, the design of a part to be produced by this process requires certain rules to be respected, and certain precautions to be taken. For simplicity's sake, we can distinguish two main geometric families of parts.
large flat parts with ribs ;
tubular parts.
4.1 Large flat parts
The aim of gas-assisted injection molding for this type of part is to increase rigidity. The gains in material and cycle time are often negligible. Nevertheless, stiffening the part with tubular sections can significantly reduce overall thickness,...

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.
