Advantages of the Injection Compression process in comparison with Classical Injection process :
- Wall thickness optimisation → Decrease of the plastic material consumption
- Decrease of the clamp force → Decrease of the energy consumption
- Injection at low pression before compression → Better distribution of residual stresses → Decrease of warpage problems → Decrease of the cycle time oIncrease of the produce and the quality of the production and decrease of the cost price.
- Fullfill mechanical requirements as listed in standards, validated by numerical simulations.
At equal wall thickness, pieces obtain thanks to Injection/Compression process have better mechanical properties than pieces obtain thanks to Classical Injection process, due to a better distribution of internal stresses.
